Your gonna love the tr-1 gold especially fishing solo. I have one on my 06’ yamaha 15hp 4 stroke and I’ll put one one every boat I own. It functions great, pretty easy to install and calibrate yourself. I go pretty far offshore though as up in the Henderson area it’s a haul to get to the fish but on 2 different boats I’ve had, never had issues with a dead battery unless I left my lights on or some dumb thing.
