Black Gold Dual Indicator System

Once you run this system on their Multi-pen Sliders, you'll want to convert all of your other Sliders by them to it as well. Both of my Pro Hunter HD's have it, and now my Ascent Verdict does too. It also has simple directions since it comes with 2 different-length screws. Just make sure you take the time to really dial in your yardage pins to get as accurate a sight tape as possible. Don't get hung up on the speeds listed for each tape.
