What it is Hareline UV Cure Light is a battery-powered ultraviolet curing light for the tying bench. It throws UV light to set UV cure resins quickly, turning a wet coating into a hard finish right on the hook. What to tie with it Use it to cure UV tying resins when you’re coating thread wraps, building durable heads, or laying down a hard shell over a body. It’s a common step for locking in nymph wingcases and backs, and for curing resin over synthetic bodies where you want a smooth, tough finish, like a Surf Candy-style baitfish. Flies and the fish they're for This light is part of the workflow for Surf Candy patterns, where UV resin is cured over the body to make a durable, translucent baitfish. Surf Candies are fished in the salt for species like false albacore, bonito, and striped bass, and they also crossover in freshwater for smallmouth and stocked trout when baitfish are on the menu. The same cured-resin wingcase approach is used on nymphs meant for trout in rivers and tailwaters, where that hard shell keeps the fly intact after a lot of fish. How it compares Compared to the Loon UV Infiniti Light, the Hareline UV Cure Light runs on AAA batteries and comes in at a lower cost. The Infiniti is rechargeable by USB and is described as more efficient, but at a higher cost.
