Question. how to best mark your spot? Obviously you can't put a buoy on it or else other people will find it and fish it. I don't have a super fancy depth finder or hand held GPS. Can I just "drop a pin" with my iphone and then try to relocate it based on that and also using my visual landmarks? I also have the Navi app on my iphone too.
My advice would be to mark the spot where you want to drop your BP's with a marker buoy. Once that is done, pull up next to your marker buoy with your trolling motor and drop your tree(s) right next to your marker. After the tree is sunk, use your navionics app on your phone and put a marker on the app where you dropped your tree. Should be able to find your BP every time. I also do not have GPS on my depth finder and rely on the navionics on my phone to find my BP's. I find them every time and I used this method.
