Hi,
I've got a Helix 7 Mega SI GPS G3N (SW Version 2.800). I've connected an XI 9 1521 transducer, but when I go to select the transducer in the settings, my only options are "High Wide Chirp" or "HB 83/200". Is this normal? It seems the High Wide Chirp will work, but my previous G2 unit would actually show the model number of the HB transducer as an option so I'm a little confused.
Thanks,
JB
