While doing a bit of line replacement community service for my fellow swamp divers at Brod's Wreck Alley off the Giant Stride, my primary mask flipped off my isolator and decided to take a dive without me in it Sunday morning. Atomic Frameless Clear with a custom length sewn-on black slap strap lost approx 50-100ft toward shore off the house boat. $20 reward. Please send my mask home.
