H2O Tools Inon Optimization Knobs for Inon Strobes

This set includes two knobs.  The image above shows an o-ring.  The o-ring is not included.

The knobs fit over Inon strobe knobs.  These knobs are larger diameter and longer.  This makes adjustment of Inon strobes easier for those divers wearing gloves or have large hands.

The H2O Tools Inon Optimization set fits Inon Z-240 and Inon D-2000 style strobes.  It does not fit the S-2000 type strobes.
