Hello,
I installed E120 chartplotter in my 2011 Twin Vee and have existing Airmar transducer,
What kind of adapter/connector do I need to connect between this two?
Please see photos attached.
Thank you.

Hello Erez,

The E120 does not have any fishfinder hardware built into it. It is however compatible with the cp370 fishfinder module. A concern I have is the transducer socket has corrosion and will need to be cleaned out. Do you know the history of this transducer and was it known to be operational? If the transducer is good you can install a cp370 E70297 and you would need to connect it into the STHS of the E120. Does this boat have Seatalk HS switch(8port) or a HS5 switch(5 port)?
