help-' modify a fishfinder to make it remote(rf) from sensor'
a present system using this is the Smartcast by Hummingbird,
would it be possible to buy one of theirs and copy it by observation?
I need to modify a fishfinder to make it remote from it's sensor,
i guess by encoding the transducer signal to radio and decoding to the fishfinder.
I know the the transducer has to be initially sounded, and maybey the pulsing frequency be adjusted, so there need to be two one-way signals.
