The Jet Diver&';s unique, buoyant design collects water pressure against its wings to dive; yet when pressure is relaxed, the Jet Diver will float off of structure. The preeminent diver for river back-trolling applications, the Jet Diver enables the presentation of lures and baits tight to the river bottom where most fish are found, without getting hung-up in this difficult environment. Trolling anglers incorporate Jet Divers as controlled-dive tools that are highly capable of bumping over bottom structure, and floating free should they become stuck. Five sizes target water depths from less than 10- all the way to 50-feet deep. See Tech Report #4, Diver/Bait Back trolling Techniques and Tech Sheet #531, The Jet Diver.
