The OR37R SST Pro Mag Planer is Off Shore's bigger badder brother to the OR12 Side Planer and OR34 Mini Planers. It pulls more weight than any in line board available! The SST Pro Mag Planer was designed to be correctly balanced for pulling heavy weights, no modifications or additions are needed! The OR16 (Red) clip on the tail of the board ensures that your board will stay on your fishing line when you are sure to place your line behind its center pin as the instructions indicate.
