This set has shallow indents that allow the climber to dig into the hold about 3/4 of a finger pad. On vertical walls, you can set V2s. In steep terrain, expect about V7. There is plenty of room for one hand and several offer room for hand-matches.
Smallest hold measures 4-1/4" wide x 3-1/2" tall x 1-1/2" off the wall
Largest hold measures 8-1/4' wide x 3-1/2' tall x 1-5/8" off the wall
