INTRODUCTION TO DEPTHTRAX® INTELLIGENT SONAR

DepthTrax® Intelligent Sonar uses SONAR sound waves to detect depth and define bottom contour, composition, and structure. Using specialized microprocessors, these sound waves are generated by the DepthTrax® display and sent to the DepthTrax® Sonar Sensor (Transducer). The sonar sensor, acting first as a “speaker”, emits these sound waves as a series of pulses. Then, microseconds later, the sonar sensor switches to a “microphone” and listens for the return of the pulses as they bounce off of objects in the water column (referred to as “echoes”). The “echoes” are sent back to the display where, using proprietary algorithms in the DepthTrax® software, they are analyzed for location, size, and composition. These signals are then arranged by DepthTrax’s® Human Interface Software, filtered, and only the depth readings are shown on the display.

SHOOTING THROUGH A BOAT HULL

The DepthTrax® 1H advanced sonar capabilities allow it to “Shoot-Thru” the bottom of a boat, canoe, kayak, etc.

• The hull must be made of solid fiberglass, or a maximum of 1/8” (3.1 mm) aluminum, and be in direct contact with the water, with no air pockets.
• The device will not work through wood, plastic, or any composite material.

To “Shoot-Thru” the Hull of a Boat, Do One of the Following:

1. Place the sonar sensor in .5 inches (13 mm) of water against the hull bottom.
2. Coat the face of the sonar system with petroleum jelly and press it against the hull bottom with a twisting motion.
3. Place the sonar sensor in a plastic bag that is full of water and place it against the hull’s bottom.

NOTICE: Some boats have a hollow space between the floor and the hull bottom called a bilge. The DepthTrax® 1H will not “Shoot-Thru” in this type of boat unless it is placed directly against the hull surface that is in direct contact with the water. Refer to our website for more advanced instructions.

SHOOTING THROUGH ICE

This device has advanced sonar capabilities also allow it to obtain depth readings through solid ice. You MUST use special techniques to obtain readings through the ice:

NOTICE: The ice must be smooth and free from excessive air. Air will show up as white imperfections inside the ice. The ice must be black in color.

To Shoot Thru Ice:

1. Clear away snow to expose the ice surface.
2. Place a small amount of liquid water on the ice and set the sonar sensor side of the device on the water.
3. If there are any air pockets between the device and the ice, or the water below the ice, the device will not work properly and will require you to use more water, try another spot, or cut a hole in the ice to use.

INFORMATION: You can also use the “Plastic Bag” and “Petroleum Jelly” instructions in the “Shooting Thru a Boat Hull” section for shooting through the ice. Visit our website for additional suggestions.

SCANNING FOR DEPTH CHANGES (SIDE-SCAN)

The DepthTrax® 1H has the ability to be used as a sideways scanning sonar depth sounder to search for drop-offs.

To Side-Scan:

1. Activate the Depth Reading feature.
2. Place the device perpendicular to the water surface to obtain a correct depth reading.
3. Once a correct reading is obtained, move the DepthTrax® 1H around in a scanning motion (similar to using a flashlight).

NOTICE: To obtain depth readings during side scanning the sonar signals must be directed at a solid surface that is within 300 ft (90 m) to function properly. You must be certain to aim the device at an object or the bottom within this range.

USING FOR DIVING

The DepthTrax® 1H is waterproof to 150 ft (45 m), allowing you to use it as a range finder or target finder for snorkeling or diving. Keep in mind that the sonar signals must be directed at a solid surface that is within 300 ft (90 m) to display depth readings.

• You must be certain to aim the Device at an object or the bottom within this range.
• ALWAYS be certain to attach the Wrist/Safety Strap to your person, as the device will float to the surface if released.

1. Nothing Happens When I Turn the Power On
   Make sure that you have installed a good battery. You may also need to test the battery in another device to ensure they are charged. If in doubt, replace the battery with one from a newly opened package.

2. The Depth Reading Is “—”
   Make sure that the sonar sensor is in direct contact with the water and that you are operating the unit in depths between 2.5 and 300 Ft (.8 to 90 m). Be aware that the depth signal is sent from the sonar sensor in a manner similar to that of a flashlight beam. Holding the unit perpendicular to the water surface will ensure accurate readings. The unit will not function properly if there is air between the sonar sensor and the water surface; keep this in mind when using the device through a boat hull or ice.

3. The Depth Reading is Incorrect
   Make sure that you are pointing the sonar sensor perpendicular to the water when trying to obtain depth readings.
   Extremely heavy vegetation may confuse the sonar causing it to misinterpret the depth. If you are certain that the readings are incorrect under these conditions, discontinue use.

4. I’m Not Getting A Reading While Trying to Shoot Through My Boat Hull or Ice
   Shooting through the hull of a boat/canoe or ice can be difficult, as hidden air pockets will prevent you from obtaining a reading. Make certain that the hull or ice is solid from the surface to the water with no air bubbles and/or gaps. Shooting through composite hulls (plastic) or cloudy ice is not possible as tiny air bubbles are usually present in these situations.

FREQUENTLY ASKED QUESTIONS

Where do you mount a depth finder?

On outboard and sterndrive vessels , you should mount the transducer in front of and close to the engine or engines. On inboard vessels, you should mount the transducer in front of and far away from the engine propeller and shaft. On single-drive boats, you should not mount the transducer in the path of the propeller.

What is the warranty on Hawkeye?

Gradient Lens Corporation warrants that all Hawkeye® borescopes and accessories manufactured by Gradient Lens Corporation will be free of defects in materials and workmanship for one year from the date of first retail purchase.

How deep can a depth finder go?

Many fish finders can be used as a depth finder, but to a limited range. Average fish finders have a depth range of about 100m (320 feet) below the surface, thanks to their high-frequency wide-angle sound beams. Depth finders, on the other hand, can detect depths as low as 600 feet and more.

Why is Hawkeye called Hawkeye?

The name is Hawkeye was originally applied to a hero in a fictional novel, The Last of the Mohicans, written by James Fenimore Cooper. Cooper had the Delaware Indians bestow the name on a white scout who lived and hunted with them.

What is the purpose of a depth finder?

How does a depth finder work?

A sonar device sends pulses of sound waves down through the water. When these pulses hit objects like fish, vegetation, or the bottom, they are reflected back to the surface. The sonar device measures how long it takes for the sound wave to travel down hit an object, and then bounce back up.

How much power does a depth finder use?

Excluding special super compact fish finders, most fish finders use DC 12-24 volt power supply. As long as the voltage is between 12 and 24 volts, the fish finder unit will function properly.

How fast can you go with a depth finder?

Fish finders with transducers that are installed properly can mark the bottom at relatively high speeds — up to 40 mph in some cases, though the slower the boat speed, the better the on-screen images.

Will a depth finder read out of water?

It is not recommended to run a FishFinder and transducer on a boat that is not in the water as you will not get any readings from the transducer.

How much does Hawkeye weigh?

A master marksman and longtime friend of the Black Widow, Clint Barton serves as the Avengers' amazing archer. 230 lbs.

What is down imaging on a depth finder?

Down Imaging, as the name suggests, is the ability on fishfinders to provide detailed picture-like images of the bottom and structures directly below the Boat. The picture-like images are displayed using specific Down Imaging software that represents the return Sonar signal in a more realistic manner.
