Garrett Pro-Pointer (first gen) retainer ring

This adds a secure hole to the Garrett Pro-Pointer (first gen) which was included in future Pro-Pointer revisions. I tested another version (Not the linked one but looks the same design) but it was too loose and flimsy so I decided to design a different style. I tried for the lowest profile with keeping up the strength of the ring and hole. It is slightly threaded to fit over the threads snuggly, and is best put on without the o-ring and then add it back on when completed. I just wanted to share what I made in hopes someone else could also find some use. It will require some sort of spacer as laffranchi63 added, which I haven't added in yet. I ended up finding a plastic quarter and am using it as my battery spacer, it seemed only appropriate. Thanks!
