What it is
Hareline Tungsten Eyes are tungsten dumbbell predator eyes for weighting flies. They’re extremely heavy, so they make a fly sink fast, and they have a realistic eye look with a bright iris and a dark pupil. They’re tough in normal use, but like any hard dumbbell they can crack if a fly gets smacked against something solid.
What to tie with it
Tie them in as weighted eyes on streamers and baitfish patterns to get the hook riding right and the fly down deep. They’re a go-to move for fast water and ultra-deep water where you need the fly to drop quickly, and they also let you keep the profile compact by using a smaller eye for the same sink rate you’d get from a larger, lighter eye. Use them the same way you would other dumbbell eyes, locked down with tight wraps and solid thread tension.
Flies and the fish they're for
The Clouser Minnow is a classic place for tungsten eyes when you want the same pattern to get down quicker or probe deeper runs. Fished in freshwater, that’s a staple for smallmouth and largemouth bass in rivers and lakes, and it’s also a common choice for stripers. In saltwater, a Clouser with heavy eyes is a bread-and-butter fly for species like redfish when you need to reach fish holding deeper or in stronger current.
How it compares
Compared to other dumbbell eyes, tungsten sinks faster and gets you down with less bulk. Compared to Double Pupil Brass Eyes, brass is lighter and fits better when you’re fishing shallower or slower water.
