Just got a Helix 7 CHIRP SI GPS G2N, it comes with a XNT9 SI 180T transducer. I want to mount it up front since I’m up there all the time. The screen is going in the front of the boat. Should I exchange that one for the XTM9 SI 180T or just buy the trolling motor adapter kit, ADXTM9. Hummingbird said it is an even exchange, and that the XTM9 is a “puck” style transducer. What does that matter? Thanks for any advice in advance. Have been looking at the Cable Savers by Cornfield Crappie also; anybody use those? They look like it keeps the cable neat and protected.
