Will a transducer read depth out of water?

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.

Will a boat depth finder work out of water?

Here's the quick answer: No, you can't use a fish finder out of water, because the transducer is unable to send or receive sonar signals in air. In other words, the transducer will not work outside of water, and needs to be properly submerged into water in order to function.

Does transducer read depth?

The depth transducer is mounted on the transom about 1' from the side. I adjusted the height so that the line drawn on the transducer lines up with the bottom of the hull. It reads depth well at trolling speeds, but after planing out, it starts to read intermittantly and eventually stops reading.

How deep in the water does a transducer need to be?

Tip # 3 Waterline

Thirdly the best bet when mounting your transducer to read at speed is to have the bottom of it 3-4 mm below the waterline. Because the transducer can only ping in water so you do want it submerged. If it's too deep sometimes the front face of it will create turbulence and bubbles = bad.

Why is my transducer not reading depth?

There are several reasons a transducer might lose a depth reading when travelling at high speeds. It could be related to the transducer's mounting location, device settings, or the vessel could be outrunning the return signal if it is moving too fast.

Should transducer be flush with bottom of boat?

Ideally you'll want the transducer about flush with the bottom or hull of your boat. It could be too deep but it won't hurt to try it. If you can't get a bottom reading going wide open throttle you'll want to adjust it.

Why is my fish finder not showing depth?

Problem: Incorrect Depth Readings

Verify that there are not two sounders operating close together. Inspect the transducer connectors and pins for signs of corrosion. Perform a basic cavitation check. Verify that the upper and lower depth limit settings are properly set.

Why does my Lowrance not show depth?

No depth reading at any time: Clean the bottom of the transducer with a soft damp cloth to remove any marine growth or debris stuck to the active faces of the transducer. Any dirt, weed etc stuck to the face of the transducer will dramatically reduce performance.

How far away from motor should transducer be?

The ideal mounting location on a boat powered by an outboard or an I/O engine is about 18-24 inches starboard of the engine's lower unit. If the boat has inboard power, mount the transducer far enough to starboard to clear any propeller turbulence.

Why does my Garmin depth blink?

If the Range is manually set to a depth that is shallower than the actual depth of the water, the FishFinder or Sounder will not be able to accurately read the water depth and the digital number for the depth will begin to blink.
