Another test that may work is to place a hard, flat reflecting object on
the ground with its plane perpendicular to the ray from the transducer.
A 2-foot square of plywood should do. This might be 3-4 feet from the
transducer. If the depth sounder is working, you should get a reading
although it is certain to be incorrect due to the differences in
velocity of propagation between water and air. I guess it ought to read
a greater distance than if it were immersed in water.

If you get nothing at all, or get just gibberish, you may have a problem.

Let us know.

Good luck.

ahoy. I have a new2me, never been wet boat on the hard. Is there a way
to see if the depth sounder works? The readout thing powers up if you
hook 12v to it. Can you somehow test the transponder widget? thanks as
always and smooth sailing.


Stick your ear up to the transducer while it is running and listen for
the "clicks". If yes then "OK on Transmit" if no then "maybe no workie"
While unit is running, have another person watch the readout, while you
vigorusly rub your hand across the face of the transducer. If readout
shows lots of flashes, or sparlkles, the "receiver Ok", if not, then
"maybe no workie". More than that you need some specific test equipment.


Me lets hope this doesn't digress into another "Flame War"....
