Need something a little more substantial to get a hold of when focusing your PST? Then this is just what you've been waiting for. At 1.125" in diameter this knob is over twice the size of the factory focus knob, affording you a finer focus, better feel, and greater ease of use when wearing gloves or if you have arthritis. This knob is easy to install and requires NO modification of the PST, it merely slides over the factory knob and is held in place with a set screw. This is a must have item for the Coronado PST!
