Just installed the Helix 7 Chirp Sonar/GPS G2N on my bow. Ihooked it up to the US2 transducer on my Terrova. Which transducer do I selectin the menu on the Helix? I want to still have the unit chirp, which I was toldby Brian at BBG that it would even thru that transducer. If all of that iscorrect, is there anything else I need to do?
