Hello from Maryland

I'm new to this. That said, I'm asking for advice on a specific model I should be looking for. I have a Boat and fish the Ocean. I want to be able to check the baits behind the Boat and on the Outriggers. I will be Trolling (Boat will be moving. for those that may not know). I would also need the Drone to return to a moving base. Thanks for your help.
