Looking for advice for gps/fish finder for my 20ft Bennington pontoon. Wife said sell Grady white and I did getting older lol. My Bennington came with a cheapo Garmin haven't used it yet but looking for recommendations from your experience. Mainly fish Keuka we have a place there mostly for Lakers perch etc..to many options out there haven't been up to date on fishfinders. Will want to have it connect Yamaha outboard for engine data. Appreciate your help and recommendations
