The Sport Diver reel is supplied with a stainless steel locking screw. The end of the screw is modified to prevent it from unscrewing from the frame unintentionally.
Spool locking is accomplished with two (2) large holes which enable the screw to penetrate and provide a positive lock.

Spool tension is continuously applied with Manta's innovative wave washer. See instructions for details.
