I have 3 helix gen2 units all with updated software. Bow is a 12 g2n di, works great, console ram mount is a 10g2 mega si, works great. Console is a 12chirp 2d GPS. I had a transducer go bad about 12 months. Replaced it 4 months ago and it just went bad. This one is mounted in the bilge for shoot through. I can switch to the 10 transducer and it works fine. Do I just have bad luck or can the unit be causing the transducers to go bad? I will change it out again but it's a pain and if the unit can cause this I would like to get it fixed. Thanks Lee
