ultrasonic sound waves

[reefburnaby]

Hi,

It would probably work and I don't think the fish can sense if the amplitude of the sensor is not very high. I have work with those sensors in the past, but I have found that the diaghram will oxidize when placed near saltwater. So, the ultrasonic sensor slowly degrades over time. Think saltspray on lights...the same thing can happen to the tranceivers.

Sounds cool...I had to build one as a course project back in the good old days.
