A few weeks ago I found myself finishing a round in the dark. Luckily I didn't lose any discs. My buddy had one of those pin light beacons taped to his disc. Which got me thinking of getting a beacon, but also using the Glow disc I own but don't use.
I know some use a camera flash to charge their glow discs. But what about a hand held U/V-blacklight deal? I know there are avid night golfers here, so, what's the best, most affordable method?
