With a little drug-store rubbing alcohol, the new bands can be installed on slingshots with round prongs, without tools, strings, or glue. The RR-2 bands pull harder than the RR-1 normal pull, and are recommended more for hunting than general target practice. The advantage of the heavier pull bands is there is more impact when the ammo strikes the target. Also, since the wall thickness is 1/64" thicker, the bands will last longer than normal pull. The disadvantage of the heavy pull is that it tends to wear out your arm a little faster!
The left and right bands are cut from one length of tubing so the wall thickness is "matched" (balanced) for accurate shooting. CAUTION: (Powerbands that are folded and packaged curled will take on a "set", and will not shoot accurately when installed.) Trumark's pure, surgical-latex powerbands are packaged straight in sealed, air-tight, blisters that prevents deterioration. See powerband life. If left sealed in the package, the bands will last for long periods of time. Instructions are included on package. 225 Yard + Range!
PARENTAL NOTE: These bands are not recomended for slingshot shooters younger than 12 years old.
