Garmin Marine Devices will show a perfect arch or half moon if a fish enters the front of the cone and goes straight through the cone and then out the back.
How does Garmin Clearvu work?
Garmin ClearVü scanning sonar gives you a nearly photographic image below your boat. With ClearVü, you clearly see structure, submerged objects, and fish. Traditional Garmin sonar and ClearVü scanning sonar are combined into one transducer. The ClearVü feature is available with Garmin CV and GT transducers.
Why does my Garmin not show depth?
Manually adjust the Gain setting. The Gain setting is the sensitivity of the transducer. If the device is having troubles reading in certain areas of shallow waters, try decreasing the Gain setting. This will decrease the way the transducer reads stronger return signals in shallow waters.

How do I set depth shading on my Garmin?
What is depth shading?
You can set color ranges on your map to show the water depths where your target fish are currently biting. You can set deeper ranges to monitor how quickly the bottom depth changes within a specific depth range. You can create up to ten depth ranges.
What are the blue and brown wires for on a Garmin depth finder?
Blue and Brown (optional) – The Blue wire is the Tx (Transmit), and the Brown is the Rx (Receive) wire. These wires are used to share user data between the STRIKER and the ECHOMAP¹ series devices.
You will not be able to test out the transducer’s ability to read depth when the boat is not in water. Air dissipates the sound waves produced by the transducer and will cause the transducer to not be able to produce a reading.
Is it OK to turn on a fish finder 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. A normal 500w or less transducer should not have any issues when running out of the water.
How far in the water does a transducer need to be?
The transducer should be even with the bottom of the boat or slightly below the bottom. Leading edge (the edge closest to the transom of the boat). One click too high: the transducer is tilted out of the water and cannot maintain a sonar signal.
Can you see fish on a depth finder?
Finding the hard bottom is obviously useful – when you know how deep the water around you is, you can choose the right equipment and techniques. You can also get a better idea of what kinds of fish you might be able to catch. Depth finders help you find fish, but not as well as fish finders do.
What direction does a fish finder read?
If you know how to read a fish finder, you know how powerful these tools are to us anglers. Down imaging fish finders send sonar down vertical from the boat, and side imaging sends sonar horizontally away from the boat.
Sharks do not show up on a fish finder either, No you could have ten dozen Sharks under your boat and not one would show up.
How does a fish finder know its a fish?
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.
At what speed will a fish finder work?
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.
