Hereís what I got document wise, as for my location it was on the hard
when I took that photo
and got flipped on my acident
I meant where in the world are you?
Your location impacts product recommendations
OK so you have 210kHz transponder. Look for an instrument that uses the same frequency and has an NMEA
output. All manufacturers will make something.
There is no information about the power of the transducer unfortunately but not much given it's range. Or its dimensions so difficult to recommend one that will fit the hole.
By the way you need to clean the face of the transducer, it shouldn't be painted.
It will probably be easier for you to buy a transducer with a NMEA 0183
output and fit that. a 0183 to USB converter. But I would always fit an instrument to read only depth - it's quite important
Something like this would do what you want.
and this will ensure good integration
NMEA 0183 to USB
