I haven’t seen very many in hull or budget sonar setups so here is mine. It’s a Quest Teton 100 with a Garmin Striker Vivid 4cv, mounted the transducer in hull with duct seal, stuck a 2lb 7AH LiFePO4 battery in there as well with 3M dual lock and drilled a hole to run the wires through a yak attack panel grommet. The GT20 transducer works just fine for me through the kayak and the cheapo battery powers the setup all day with minimal voltage drop. Very pleased to skip buying mounts and adding clutter to my small kayak for an easy setup that just works.
