Same top quality as Anderson.

Will never strip, slip or corrode.

Impervious to salt water.

Has \"feeler pointer\" mark so you don\'t have to look at it to make fast adjustments to your Excalibur metal detector controls.

Easy to put on and take off with a small flat head screwdriver (not included).

We carry these same knobs in different colors so feel free to check out our other items.
