Attaching a Fishing Line or Tether

You can use the included nylon tether or attach the device to a fishing line on a fishing rod.

• Attach the included nylon tether to the device.
  

• Attach a 20-lb. test or higher fishing line to the device using a #3 barrel swivel with a snap, on a mediumaction or heavier fishing rod.

Fishing with the STRIKER Cast Device

CAUTION
To avoid injury, always be cautious of your surroundings when casting the device.
Towing the device behind a vessel moving at speeds faster than 8km/h (5 mph) or in choppy water conditions could result in poor sonar performance and injury.

NOTICE
Garmin is not responsible for lost devices.
To prevent corrosion, do not store the device in water, and thoroughly dry the device after use.

You can fish with the device in various ways.

• Cast and leave the device on a dedicated fishing rod so that you can continually change the device location.
  NOTE: Repeatedly casting the device as you fish provides a clearer picture of what is below the surface. This is the recommended mode of use.

• Cast and tie off the device using the included tether.

• Tether the device behind a small vessel, such as a kayak.
  TIP: It is recommended to tow the device behind canoes and kayaks, but not recommended to tow the device behind power boats while underway.

6. Structure

TIP: If the sonar view does not show returns, a small air bubble might be trapped on the pins near the power connector. Re-cast the device or tug on the line to clear the bubble.

TIP: If the sonar view shows repetitive bands, the STRIKER Cast device is likely in very shallow water. The bands are echos in the sonar returns. You can adjust the range to resolve this problem.

Adjusting the Level of Detail

You can control the level of detail and noise shown on the sonar screen by adjusting the gain.
If you want to see the highest intensity signal returns on the screen, you can lower the gain or brightness to remove lower intensity returns and noise. If you want to see all return information, you can increase the gain or brightness to see more information on the screen. This also increases noise, and can make it more difficult to recognize actual returns.

1. Select Sonar > .
2. Under Gain, select an option:
   • To allow the device to adjust the gain automatically, select Auto.
   • To increase or decrease the gain manually, use the slider.

Adjusting the Range of the Depth Scale

Allowing the device to adjust the range automatically keeps the bottom within the lower or outer third of the sonar screen, and can be useful for tracking a bottom that has minimal or moderate terrain changes.
Manually adjusting the range enables you to view a specified range, which can be useful for tracking a bottom that has large terrain changes, such as a drop-offs or cliffs. The bottom can appear on the screen as long as it appears within the range you have set.

1. Select Sonar > .
2. Under Range, select an option:
   • To allow the device to adjust the range automatically, select Auto.
   • To increase or decrease the range manually, use the slider.

Sonar Settings

Select Sonar > > More Settings.
View: Shows a Traditional sonar view or a Flasher view (Flasher View, page 6).
Frequency: Adjusts the frequency to adapt the sonar for your particular goals and the present depth of the water.

The 455 kHz setting uses a narrower beam width and is better for rough sea conditions. Bottom definition and thermocline definition can be better when using a higher frequency.
The 260 kHz setting uses a wider beam width, which covers a larger area and can allow you to see more targets, but also could generate more surface noise. Wider beam widths generate larger arches for fish target returns, making them ideal for locating fish. Wider beam widths also perform better in deep water, because the lower frequency has better deep water penetration. They can be used to search for structures such as brush piles.

Scroll Speed: Sets the rate at which the sonar scrolls from right to left. A higher scroll speed shows more detail, especially while moving or trolling. A lower scroll speed displays sonar information on the screen longer.

A-Scope: Displays a vertical flasher along the right side of the screen that shows instantaneously the range to targets along a scale.

Fish Symbols: Sets how the sonar displays suspended targets.

Restore Sonar Defaults: Restores the factory default settings for the sonar view.

Turning On the Flasher

Select Sonar > > More Settings > View > Flasher > Back.

Flasher View

The flasher shows sonar information on a circular depth scale, indicating what is beneath the STRIKER Cast transducer. The flasher is organized as a ring that starts at the top and progresses clockwise. Depth is indicated by the scale inside the ring. Sonar information flashes on the ring when it is received at the depth indicated.
The flasher colors indicate different strengths of the sonar return. The default color scheme follows a traditional sonar color palette, in which yellow indicates the strongest return, orange indicates a strong return, red indicates a weaker return, blue indicates the weakest return, and white indicates no return.

Garmin Quickdraw™ Contours Mapping

WARNING
The Garmin Quickdraw Contours mapping feature allows users to generate maps. Garmin makes no representations about the accuracy, reliability, completeness or timeliness of the maps generated by third parties. Any use or reliance on the maps generated by third parties is at your own risk.

The Garmin Quickdraw Contours mapping feature allows you to instantly create maps with contours and depth labels for any body of water (with GPS models only).
When the Garmin Quickdraw Contours feature records data, a colored circle surrounds the icon. This circle represents the approximate area of the map that is scanned by each pass.

A green circle indicates good depth, GPS position, and a good speed. A yellow circle indicates good depth and GPS position, but the speed is a little too fast. A red circle indicates poor depth information, poor GPS position, or a speed that is too fast.

Mapping a Body of Water Using the Garmin Quickdraw Contours Feature

Before you can generate a map using the Garmin Quickdraw Contours feature, you must have sonar depth and GPS position data.

You can only record Garmin Quickdraw Contours mapping only using models that have GPS. If your device does not have GPS, you cannot record contours, but you can download community contours.

1. From the STRIKER Cast app, select Chart.
2. Select > Record.
   As you fish with the STRIKER Cast device, a map is generated.
   A green circle indicates good depth, GPS position, and a good speed. A yellow circle indicates good depth and GPS position, but the speed is a little too fast. A red circle indicates poor depth information, poor GPS position, or a speed that is too fast.

When recording is complete, select > Record to stop recording.
