Gehrke's Xink Leader Sink is the perfect item when
you want your fly or leader to penetrate the surface film. It helps your nymphs reach the depths you want to achieve.
1/2-oz. bottle.
I was out on a local stream without a weighted nymph or split shot to get a soft hackle nymph down in fairly fast water. I remembered that I had the Xink in my vest so I applied some to the leader and to the fly. On a day when the fishing was not too very hot, I proceeded to catch all but one fish of the day after using the Xink. I will definitely be putting it to more tests. - Good fishing
i saw this in a store and thought well it may work and it could just be a little bottle of water, but i got it anyways. it does work ive only been able to use it two different days but on them days i was able to sink my little nymph to the bottom of a little stream that was moving kind of fast and i didnt even need splitshot
