This release is fabulous. We've used them for over 20 years. Still using the same ones from over a decade ago. We've only replaced the ones we've given away or smashed with a 18lb ball accidentally. Fished them from Montana to California, Flathead Lake to Lake Tahoe or the rivers; in 5ft or 150ft of water. It takes a little to set the tension perfectly on deeper trolls, but once you have it, it sticks and is perfectly repeatable. Usually, 'almost no' tension works for light tackle (needle-fish, crocodile, sling blades, etc., lead-core or light mono-filament) up to 2mph, down to about 35ft. Excellent product, excellent results!
