Start mode combines a timer and perpendicular distance to line display to provide the information necessary for a perfect start at the gun.

The semi-circles next to the PIN and RC buttons indicate if the respective ends are set. When both ends are set a line appears between them to illustrate that the line is set.

Timer
The count-down timer displayed as mm:ss. The timer can be set from 1:00 to 15:00.

Distance To Line
Distance To Line’ is the perpendicular distance to the user defined line. Refer to Set Start Line on page 22 for detailed information on setting the start line.Distance To Line’ is displayed in meters.
A negative Distance To Line’ means that the boat is over the line. Three hyphens—‘ are displayed when the line is not defined and a GPS signal is available. When the Distance To Line’ is larger than 1000 meters>999′ is displayed.
Distance To Line’ can be displayed with either 0.1m or 1m resolution. Refer toSetting Distance to Line Precision’ on page 31 of the Configuration section

Modes

13

Start line pacing guides
In the final two minutes of the countdown the bar graph segments will display `Pacing Guides,’ giving you an indication of whether you are on track to be early or late to the line given your current boat speed and heading. Below is a description of how this algorithm works so that you can employ this feature in your starts with confidence.
The early / late bar graph provides a graphical representation for your estimated location at the gun based on your current position, speed, Course Over Ground, and the time remaining in the countdown.
The bar graph extends above the illustrated line if the calculated future location is over the line and below the illustrated line if your future location is under the line. When no bar graph segments are showing – the “0” display – your estimated future location at the gun is between the line and 2 meters below the line. Each segment shown represents +/- 2m from this “0” location. For example, 2 bar graph segments showing above the line represents that you are predicted to be between 2m and 4m over the line at go. For simplicity’s sake this algorithm assumes the line to be of infinite length so it does not compensate for any situation where your current heading would not take you through the starting line.
The goal is to eliminate all the bar segments around the perimeter and only have the semicircles showing. This indicates that at your current speed and heading you are expected to be within 2 meters of the line at the gun.

Bar Graph (Heel or Shift)

Heading / COG Speed

Race mode displays information crucial during the race: speed, magnetic heading or COG, and heel angle or shift angle (on bar graph).

Modes

14

Speed
Speed is calculated by the GPS unit by measuring the Doppler shift in GPS signals. It is displayed in Knots (Nautical Miles per Hour).
Magnetic Heading
With the addition of a solid-state geomagnetic (compass) sensor, the ProStart’s factory default direction output is magnetic heading. The default heading is magnetic heading of the device expressed in degrees with 360° being North.
When the ProStart’s direction output is set to magnetic heading, the ProStart’s top line will show compass heading with three digits at all times. Leading zeros will be displayed when the heading is not three digits, i.e. eleven degrees will be shown as 011° and three degrees will be shown as 003°.
If you are not mounting your ProStart facing forwards on your boat you can set a “heading offset” in the device settings.
See the Configuration section on page 24 for instructions on changing the heading offset or the ProStart’s direction output from magnetic compass to course over ground.
Course Over Ground
The user has the option to substitute Course Over Ground (COG) in place of Heading. COG is calculated by the GPS unit by measuring the Doppler shift in GPS signals.
Either true or magnetic COG can be displayed by entering your local magnetic declination into the ProStart. “True COG” is referenced to true north. “Magnetic COG” is referenced to the local magnetic north. When using a magnetic compass in conjunction with the ProStart, displaying COG in degrees magnetic can be useful since both measurements will be referencing magnetic north.
By default, COG is displayed in degrees magnetic. This is done by automatically using the GPS location to compensate for the local magnetic declination wherever you are in the world. To display COG in degrees true the magnetic declination must be set to zero in the device settings. See Setting Declination’ in the Configuration section on page 29 for instructions on adjusting the magnetic declination setting on the ProStart. The ProStart displays COG only when your speed is greater than 0.5 knots. If your speed is less than 0.5 knots the ProStart will display- – -‘ for COG regardless of which direction you are moving.
Unlike the magnetic heading from a compass, COG requires movement. COG depends only on the direction you are moving, not the direction the device is pointing. If your ProStart is configured to display COG, the ProStart will give you accurate COG information regardless of the orientation in which it is mounted on your boat (i.e. mounted on the sides of a boom, or a tacking bracket on a Moth).

Modes

15

When the ProStart’s direction output is set to COG, the ProStart’s top line will show COG with no leading zeros, i.e. eleven degrees will be shown as 11° and three degrees will be shown as 3°.

Race Mode Bar Graph
The user has the option of either displaying heel or shift angle on the bar graph while in Race Mode. By default, the ProStart displays the heel angle. See `Setting Race Bar Graph Mode’ in the Configuration section on page 26 for instructions on switching between heel angle and shift angle.

Heel Angle
Heel angle is displayed on the bar graph with each segment representing 2.5° of heel. To zero out the heel angle, press RESET when the ProStart is in Race Mode (this will also zero the pitch angle which is accessible only in Bonus Mode).
Heel angle is also recorded in the ProStart’s data storage. Heel to starboard is shown as positive degrees. Heel to port is shown as negative degrees.
Each segment represents 2.5° of heel

-12.5°

12.5°

Shift Tracking
In Race Mode, the user has the option to substitute shift angle in place of heel angle on the bar graph. See `Setting Race Bar Graph’ configuration section on page 26 for instructions on switching between heel angle and shift angle.

Modes

16

When the race bar graph is configured to show shift angle each bar graph segment will represent 3° degrees of heading deviation from a device determined trim angle’. The trim angle is set automatically by the device once the boat is detected to be steering a relatively stable course for a specified length of time. The trim angle is automatically reset anytime the current heading deviates from the trim angle by more than 45°. The trim angle can be manually reset by pressing the RESET button while in Race Mode with shift tracking activated (seeSetting Race Bar Graph’ in Configuration section). This will clear the previously used trim angle and start a fresh measurement cycle for the ProStart to find the new trim angle.
See the `Understanding Shift Tracking’ section on page 37 for more detail on how the shift tracking algorithm works.
Each segment represents 3° of heading deviation

*Press the RESET button to clear trim angle

Modes

17

GPS Off Mode / SHIFT Mode
GPS Off or SHIFT Mode, allows the user to hide all of the GPS features and use the ProStart as a tactical compass. In SHIFT Mode, the ProStart will function nearly identically to the Velocitek SHIFT, a tactical compass dedicated to tracking wind shifts.
By default, GPS is on and SHIFT Mode is disabled. To enable SHIFT Mode see `Disabling GPS / Enabling SHIFT Mode’ on page 31 in the configuration section.
In Start Mode, with SHIFT Mode is enabled, the ProStart will display a countdown timer on the top data field and a magnetic compass on the bottom data field.
In Race Mode, with SHIFT Mode is enabled, magnetic heading is displayed on top. When reference angles are set, shift angle is displayed on the bottom and shift magnitude and direction are displayed on the bar graph with each segment representing 3°. Read more about setting reference angles on page 40 in the Understanding SHIFT Mode section.

Modes

18

Bonus Mode
Bonus Mode allows you to display any two metrics on the top and bottom displays as well as an additional metric on the bar graph.
By default, Bonus Mode is disabled. To enable Bonus Mode see Enabling Bonus Screen’ on page 31 in the configuration section. The options for metrics to display on the top and bottom display are: Magnetic Heading, Course Over Ground, Speed Over Ground, Heel, Pitch, or Shift Angle. The options for metrics to display on bar graph are: Heel, Shift Angle, or Off. When enabled, you can access the Bonus Screen at any time in either Race or Start Mode by pressing both the MODE and+1′ buttons at the same time (in either order). Pressing any button while in Bonus Mode will exit Bonus Mode

Searching for GPS signal
Searching indicator is displayed at the bottom and bar segments travel around the circumference of the LCD.

GPS Signal Acquired

The operation of the ProStart relies on low-power radio signals from GPS satellites that orbit the earth at an altitude of approximately 20,000 km. As a result, the ProStart must be outdoors with a clear view of the sky to function properly. Stay away from tall buildings and forests when acquiring a signal off the water since these obstacles block or reflect the signals making it difficult to obtain signal.
When the ProStart is first turned on, it must download information from GPS satellites before it can acquire a GPS signal.

The satellite acquisition process can take up to 5 minutes.

Modes

20

Using the Backlight
The ProStart features a white or red LED backlight.
With the ProStart powered on, press POWER / LIGHT to cycle the backlight between: off, white, and red.
If your ProStart has a low battery, the backlight will automatically turn off to reduce power consumption and extend the runtime of your ProStart.

The greater the damping value the smoother the heading change will be, but the slower the response will be to a change in heading. Selecting the appropriate damping level is a personal preference usually based on the boat being sailed, the wind and the water conditions. For example, in steady wind and flat water, no damping (level 0) is recommended. However, in high wind with lumpy water damping will eliminate large heading variations that can make judging a wind shift difficult. Press GUN button to save your selection and progress to the next menu, or press RESET to exit config without saving the current menu (all previous menus will still have been saved). Setting Heading Offset Options: [ -90° to +90° ] Default: 0° The fifth config menu selects a heading offset. The default is 0°.

Setting Magnetic Declination
Options: [ Automatic | -45° to +45° ] Default: Automatic
The sixth config menu allows you to select between automatic (default) or a fixed magnetic declination.
You will see dEcLinAtion’ scrolling across the bottom display and either dEF’ (default), or some angle between -45° and +45° on the top display. Pressing the RC button will increase the declination by 1° and PIN button will decrease it by 1°. Positive declination represents east and negative declination represents west.
Declination is used to display COG and Line Square To,’ in degrees magnetic (vs degrees true). This is beneficial when using a magnetic compass in conjunction with the ProStart since both instruments will be referenced to magnetic north. By default, the ProStart will use the current GPS location to calculate the local declination. This means that unless you manually set the declination to some angle other than “dEF” the compass output will display in degrees true. You can find out what the automatic value is set to simply by pressing the either the PIN or RC button whiledEF’ is displayed. In either case the first declination angle displayed will be the value that the default is set to. If you save (by pressing GUN button), while the display is showing any other value other than dEF’ your ProStart will no longer automatically determine and use the local declination on power up. To ensure automatic declination is enabled you must press GUN button whiledEF’ is displayed.

In the case where the ProStart is powered on where there is no GPS signal the automatic declination value will be 0. However, as soon as a GPS signal is acquired the ProStart will automatically update it to the determined local declination.

Now, while in Race Mode a single short press of the reset button will zero both the heel and pitch angles to the exact orientation of the ProStart unit in that moment.

Understanding `Distance to Line’

34

Understanding `Distance to Line’
Once you have set (pinged) both ends of the starting line the ProStart connects these two points in a straight line of infinite length. The ProStart calculates distance to line as its perpendicular distance to the infinite start line.
The ends of the line should be set when the bow of your boat is on the line. When you set the ends of the line, approach each ping in the same direction you would if you were approaching the line to start the race.

Pinging without the bow offset
Pinging without the bow offset, the ProStart calculates distance to line as the perpendicular distance from its current position to the straight line between its positions at the time of your line set pings.
The illustration below provides a graphical definition of distance to the start line and how you can set it when you are not using the bow offset.

Setting the Ends
The start line ends can be set anywhere along the start line. We recommend sighting both the pin and the race committee ends from outside the line. Another method is to get close to the ends just inside the line and set them. The ends can be set at any time and in any order.
1. Approach the line slowly from below with a consistent speed and heading.
2. Press the PIN / RC button when your bow is on the line.
· Press the RC button to set the right end of the line
· Press the PIN button to set the left end of the line
We recommend setting the ends of the line for the start of each race, regardless of whether the line has moved.
How to use Time and Distance
Balancing time and distance to hit the line at the gun, close hauled and at full speed is the stuff good starts are made of. To accomplish this goal, many top sailors establish a ratio of time to distance or distance to time. Conveniently in boats in the 20-25 foot range, the ratio is often 1:1. Your ratio(s) may vary. A timed run at the line is a good way to figure out your time and distance ratio.

Understanding `Line Square To’

Understanding Line Square To’ To displayLine Square To’ bearing, press the MODE and MAX buttons at the same time. Line Square To’ will appear on screen for 5 seconds. You can exit Line Square To’ before the 5 seconds is up by pressing the RESET button.

`Line Square To’ is calculated as the magnetic bearing from the right end of the line to the left end of the line plus 90°. See image below for an illustration of how this figure is calculated:
155°

Pin + 90°

Race Committee

IMPORTANT – In order for the Line Square To’ output to work with your magnetic compass, you need to ensure your magnetic declination is set to automatic (default), or the accurate magnetic declination for your sailing venue. See the Configuration section on page 29 for instructions on setting magnetic declination for the ProStart. How to useLine Square To’
For a standard upwind start where the line is set perpendicular to the wind direction Line Square To’ is a tactical aid which gives you information about which end of the line is favored. If the start line is set perfectly theLine Square To’ angle should match the wind direction. Inevitably, this is not the case so shoot head to wind, check the bearing on a magnetic compass and compare this measurement with `Line Square To.’

Understanding Shift Tracking

37

The right side of the line is favored when the Wind Direction is to the right of Line Square To.’ The left side of the line is favored when Wind Direction is to the left of Line Square To.’
How much does `Line Square To’ matter? Ten degrees of line bias favors one end over the other by approximately 20% of the length of the line.

Understanding Shift Tracking
There are three ways to view the shift tracking feature: it can be displayed on the bar graph in Race Mode, the bar graph in Bonus Mode, or numerically in Bonus Mode.
See the Configuration section on page 25 to see how to change how you view shift tracking.
The shift tracking algorithm starts by detecting when the boat is sailing a steady course. This is accomplished by comparing the current heading to a rolling average of previous heading measurements. Once the current heading falls within a specified bound of this rolling average the boat is determined to be sailing a steady course and a “trim angle” is set to the current heading.
When a trim angle is set the shift measurement will display the damped difference between the current heading and this trim angle. The damping reduces the algorithm’s sensitivity so as to only capture larger variations in heading angle, ideally from wind angle changes, and not any smaller heading variations due to wave action or other noise effects.
The trim angle remains constant until the current heading differs from the trim angle by more than 45 degrees. Once the trim angle is reset the shift angle will no longer display and the algorithm will again start measuring for when the boat has reached a new steady course.

Understanding Shift Tracking

How to use Shift Tracking

39

How to use Shift Tracking
While sailing a close-hauled course upwind the shift tracking feature will give a measure of how much you are being lifted (wind is shifting towards the stern of the boat), knocked (wind is shifting towards the bow of the boat), or sailing a straight course. This assumes that you are sailing your boat at a consistent angle to wind, i.e. the wind is dictating your heading.
The trim angle will automatically reset every time you tack. If you sail a relatively steady course after you tack, you’ll see a new trim angle is set when the arrow appears at the top of your display. From this point on – until you deviate from this course by more than 45°) the bar graph will show segments to the right of the arrow if your heading is deviating to starboard of the `trim angle’ and to the left if your heading is deviating to port.
Now let’s say you just tacked onto port tack, once your new heading angle is stable the trim angle will be set to your new heading and you’ll see the arrow display. From this point on – assuming you are steering your boat to maintain a constant angle to the wind – any heading deviations displayed on the bar graph can be assumed to be wind shifts. So, if you notice one bar segment displayed to the right of the arrow, then 2, and eventually 3, you can assume that you are now getting knocked between 9°-12° (3 segments at 3°/segment), and you may want to consider tacking to take advantage of the lift on starboard if your position on the course allows. Conversely, if you see 3 segments showing up to the left of the arrow while on port tack you can assume you are being lifted between 9°-12°

Understanding GPS Off / SHIFT Mode

40

Understanding GPS Off / SHIFT Mode
GPS Off or SHIFT Mode, allows the user to hide all of the GPS features and use the ProStart as a tactical compass. In SHIFT Mode, the ProStart will function nearly identically to the Velocitek SHIFT, a tactical compass dedicated to tracking wind shifts.
To learn how to turn on SHIFT Mode see `Disabling GPS / Enabling SHIFT Mode’ on page 31 in the configuration section.
In Start Mode, with SHIFT mode is enabled, the ProStart will display a countdown timer on the top data field and a magnetic compass on the bottom data field.
In Race Mode, with SHIFT mode is enabled, magnetic heading is displayed on top. When reference angles are set, shift angle is displayed on the bottom and shift magnitude and direction are displayed on the bar graph with each segment representing 3°.
Heading in SHIFT Mode
Heading is the magnetic heading of the device expressed in degrees with 360° being north. Heading is displayed on the top line of data in Race Mode. In Start Mode heading is on the bottom line and countdown timer is on top.
Setting Reference Angles in SHIFT Mode
There are two reference angles, starboard reference angle and port reference angle. The reference angle is a user input heading that is the optimal heading on a given tack. The reference angle for the starboard and port tack can be set by pressing the (port) or (starboard) buttons.
The shift angle and shift indicator are displayed when the heading is within 25° of the reference angle. The reference angle is not displayed on screen.
When both the starboard and port reference angles are set and are both within 25° of the heading, the closest reference angle will be displayed.
Clearing the Reference Angles
You can clear the reference angles by pressing the square and triangle buttons at the same time.
SHIFT Indicators
The shift indicators are only displayed when the heading is within 25° of a reference angle.

Understanding GPS Off / SHIFT Mode

Bar Graph
Right segments on the bar graph at the top of the screen represent clockwise rotation or a right shift. Clockwise rotation or a right shift is a lift on starboard and a header on port. Left segments on the bar graph at the top of the screen represent counter-clockwise rotation or a left shift. Counter- clockwise rotation or a left shift is a header on starboard and a lift on port.
Numerical Display
The shift angle (difference between set reference angle and heading) is displayed numerically on the bottom line of data. Lifts are always a positive number and headers always a negative number.
Start Mode with SHIFT Mode enabled
Timer
The countdown timer is displayed on the top line of data. The count-down timer displayed as mm:ss. The time can be set from 1:00 to 15:00. +1 button adds a minute to the timer The GUN button starts the timer. While the timer is running GUN syncs down to the nearest whole minute.
Heading
Heading is displayed on the bottom line of data. Heading is the magnetic heading of the device expressed in degrees with 360° being north.
