The Koah RSC 60M is exactly what the industry has been waiting for. Rock solid construction, rugged slide on base, balanced wheel design, soft grip reel knob and a smooth drag that works under any circumstances are just a few of the advantages. The reel also has a ribbed center wheel to assist in line loading and prevent slippage. The bottom of the reel has a hole that lines up with the base to allow for fixed mounting to the speargun with the provided longer screw.
