I have been working hard for 10 years to make a planing fishing float that can cover all the bases. My goal is to license the patent. I do not sell them yet because i have not figured out pricing. I may see what they bring on eBay??? I call them ProwlerPlaners. They are very hard to make and I have a very high scrap rate. Machining high density Styrofoam is difficult because it melts on dill bits and worse yet on the band saw. I have to go very slow and back out many times to keep from melting them.
They can do it all! - for casting and retrieving, trolling or river fishing – fish from shore, anchored, drifting or trolling - slip rigged or fixed depth - steer them anywhere you want down stream or set it and forget it in the current - flip direction when given a little tug or plane just one direction by moving the weight to a keel - steer under trees or docks and come back out - troll from shore - put in the hydrofoil for high speed walking, paddling, currents or trolling! Fishing in rivers with wicked currents and eddies is a riot but they can help catch fish in many ways.
They can they can pull BIG lures for their size. They cut a furl like a water skier cuts out to the side of the boat with the hydrofoil.
They can handle fairly big lures for their size!

Here are a couple 3" Prowlers pulling a 4.5" lures.
