I have helix gen 1 Si up front transducer mounted to the bottom of my Ulterra and absolutely love it!
have had it up front for close to 3 years. I blue gill fish a lot and have found hundreds of beds that I would have prolly never found if I hadn’t of had it ! Also comes in handy when trying to figure out where the grass lines are.i turn down the speed to 2 when going 1-2 mph and find lots of stuff barely moving !
