first off im not a garmin man but i need to get in on the livescope bandwagon. first off which head unit would be the recommendation of choice? I see with the SV units they vary wildly in price between the transducers- which would be best for hooking up to my ultrex if thats even an option or do i need to run the transducer to the back? I plan on mounting the livescope on one of the all aboard ladder's mounts like the HB360 he makes for the ultrex. thanks for any recommendation.
