I can't think of anything that they will improve on shallow water anchors, but I can see some with trolling motors, specifically Minn Kotas. I believe that Motorguide already makes a wireless foot pedal but I would like to see Minn Kota do it. I like to move my Minn Kota Ulterra's foot pedal around from one side of the boat to the other depending on what side the docks or shore I am fishing are on. It's a pain with a wired foot pedal like the Ulterra has. It would be nice if the Ulterra had a wireless foot pedal with hard-wired backup. Like you could just whip out your cable and connect it to the foot pedal and trolling motor with quick detach hardware if the wireless went out for some reason or the battery died. It would also be nice if you could quickly charge the foot pedal off of the boat batteries when you plug in your boat's batteries each night.
I'd also like to see a "Summon" feature on the Minn Kota. This would be similar to Tesla's summon feature. So you could launch your boat like in the Minn Kota Ulterra commercial where the guy launches his boat and then guides it to the dock with his remote. However, with the summon feature you could just walk to the dock and hit the "summon" button and rather than have to manually guide the boat to the dock with your remote the trolling motor will do all of the work for you and come right up to the dock so you can keep your hands full with your tackle and rods that you are carrying down. Sort of like when the Silver Surfer summons his board by saying, "To me my board". You also don't have to worry about coming in too fast with your trolling motor and crashing your boat into the dock.
What will the next improvements to Trolling Motors and Shallow Water Anchors be?
