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"....

Years ago, the Ross Labs Service Tech used a 4Ft 8" PVC Pipe that was
glued to a 1 Ft Square piece of Telfon as a Transducer test stand.
It was calibrated at some depth, (which I don't recall) for their
200Khz Transducers. He would just place the transducer across the top
of the pipe, and measure the return signal at the detector diode on
his Shop Standard Transceiver. Ross would reject about 2% of the OEM
Transducers due to lack of receive sensitivity.
