Hi- nothing earth shattering, but I attached this epoxy-coated neodymium magnet to my sand scoop to grab the ferrous stuff for me, so I can focus on the (sometimes!) better catches.
Gary recommended something similar - gluing a magnet to the back of his pinpointer to help find magnetic targets. I’ve got a few magnets and have been meaning to glue one on there. Has this done much for you?
