This spring fishing the Niagra Bar used these and was very impressed . Have not been able to find them since. Did a search today and found them. Anybody else ever use them . They are just like a Dipsey Diver except your line passes through them ie(they slide on your line) so upon landing a fish your not stuck with a 8-10 ft leader upon landing a fish. You can run your bait / lure 10-200' if your heart desires behind the diver and upon release they slide up to your swivel which can be 3-4' from your lure.
