Guys I swapped my structure scan transducer with a totalscan and gen2 with carbon. The carbon didn’t auto find it on channel 2. Haven’t had it on water yet but I’m trying to understand different options of the new unit. Is the chirp just better picture? Is the totalscan usable for temperature? Also can I turn channel 1 off if I’m only networking the normal transducer from another unit? Thanks for your help guys.
