The Jumbo Jet diver is perfect for Back Trolling any baits or plugs for salmon in our local rivers. 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.
