i put a 575 hummingbird on my trolling motor but have no finder for the transom ( well i do have a older humm. tcrid-1 finder but would like to have something newer) but would just like to stay cheaper or should i go with the piranhamax 240 with the triple beam sonar .
i know these questions have been asked 1000 times but i can't find them with the items i am looking for .
thanks for the help,
Scott
