I have a Helix 7 SI CHIRP Sonar GPS G2 on the cockpit of my bass boat. I love all the functionality but when I fish from the front of the the boat I can look at my finder. I am planning to put a second unit at the front but I don't know which tech (SI, DI, Sonar, GPS) would be the best to have at the front of the boat. I would love 360 Imaging but can't afford it. Should I put the Helix 7 SI at the front and just get a Helix 7 GPS Sonar for cockpit?
Which setups do you use?
