Prowlers are made of molded high density rigid EPS foam.
The latest Prowler design has the maximum in functionality and versatility.
There are now 3 locations for the weight. Moving the weight to one of the keels will predetermine planing direction if you don't want it to flip.
Pushing the retractable hydrofoil stabilizer forward greatly increases maximum speed and usable lure resistance. This will make it very difficult to flip and makes sense to use along with moving the screw to a keel so if you stop it will always start off again in the desired direction.
The Ultimate Steelhead Fishing Float "The Black Night Prowler"
These are great for Steelhead fishing from the bank, boat or wading. Black bobbers seem to catch more Steelhead and I used a black Sharpie to color this one only leaving one surface orange and one green for direction detection. Below shows the standard slip rigging assembly spacing to go across fast shallows or get down in slow holes. Flip the bail or back reel to get wherever you want to start a free drift. Some light jigging or trotting on the drift and drop is good practice.
The fin is crimped to hold it in the slot. The tail is slit for testing direction control but had no affect.
The stabilizers are crimped to hold in place in the slot and the tail was slit and bent for testing directional control affect.
R&D Update 9/20/2013
Connecting the fishing line to the Prowler "does not" require breaking the line unless you want to slip rig them. The Prowler body has a hole and a slot to lay the line in and secured with 2 black pegs. To slip rig you need to thread on the black pegs. Slip rigging provides the ability to jig them vertically when the line tension is slack. The pink "Bad Beads" pop on and off the line and are used to set the minimum and maximum depth. The small slotted plate that is held in place with screw, allowed me to find the best possible location for weight balance of a wide range of lure weights. This will balance and control the angle of the body to provide the best possible planing action and flipping consistency through the weight range.
R&D Update 9/23/2013
Tested a variety of stabilizers to keep it from flipping and allow faster trolling and current speeds. The stabilizer keeps it from rolling and gives it more power to overcome line drag so it planes out at a wider angle.
You can see the furl that it throws off, similar to what a water skier makes when leaning out to get way out from the side of the boat. This little planer with the stabilizer has as much planing power as much larger and heavier boards. The goal is replacing size and weight with lift and stabilizers.
This allows trolling with 2 or 3 on each side and with little worry about accidental flipping and tangling of lines. Stabilizers (P2 and P6) planed farthest out with large diving lip lures with speeds from .2 to 2 mph.
Fairport Harbor, Painseville, OH - Wind at 5 to 15 mph, wave height .5' to 1.5' - Trolling DualFins with a plastic putty knife tail had an interesting result! It would plane out to the side, flip direction, run near the center of the wake and again flip direction running back out to the same side. It continually ran about 60' side to side with a 100' foot of line out and 35' more line in leader. With a buoyant diving lure at 1 mph it took about 20-30 seconds to get out to the side and only 10-20 seconds on the run towards the wake.
The lure depth range and the amount of lure action must have varied widely considering the changes in speed and direction of the DualFin as it covered the area.
When it slowed to boat speed out to the side and when nearing the center of the wake it would flip. It was pretty cool having an automatic flipper that stayed to one side, continually repeating a 90 degree swing. I need to test more lures and at various speeds to see if I'm onto something that can hold true for a wide range of variables i.e. speeds, lure types. I found that only having to steer the boat and watching the DualFins flip on their own...entertaining.
Hear is the latest design that needs testing in the boat for speed range, planing apex angle, lure weight range, different lure types and resistance to flipping. Appeared to improve all factors in the pool test. At as`the speed increases more water is pushed up by the keel and hits the wing, stabilizing the the attack angle in all directions but still providing the means to flip direction with a tug or restart.
