I am interested in a "continuous use" laser in a (somewhat) "compact" size---Arc LS or possibly even a Mega Micro size or thereabouts. I had an individual build me one into an LS shell some time ago however the electronics work was shoddy and "continuous use"--5 minutes or so at a time was and remains impossible. Ideas? I'd be interested in a stock item or, a custom....any interested builders out there for this job? By the way, for use as a pointer and nothing more.
