One thing I did with my tiller was add an extra ball mount and power cord at the helm. I have 2 Helix 9’s one of which has DI and SI. I run one Unit as my LCR/SI/DI and use my other Helix as my GPS/Mapping. Gives me 2 9” screens side by side to read when backtrolling. I can also move one 9 up front and connect it to the trolling motor Transducer when bass or panfishing. For another minor extra expense(in the overall scheme of buying a boat)adding the Ram Mount and Power Cord it adds some wonderful versatility! I also am enjoying the Follow the Contour option! Another add on, but am learning to like that a lot, especially when trolling cranks!
