See What Other Divers Think
I had the chance to "preview" and play with one of these before they were released... During a surface interval, Kevin handed this shield to me and I immediately went loopy (I get excited for cool, new gadgets, there, I admitted it) and put it onto my Guardian (usually covering the clear mask with a golf towel in storage, it doesn't really protect all that well) and exclaimed; "When are you going to release these?!" I snapped it on (went on easily) and marveled at how well it fit the mask. I said, "This will keep those nasty scratches off the lens" and was absolutely thrilled. I then looked at the snug fit and figured out it would also be a perfect blindfold for pool (or clear water) Blackwater training. No more wrestling with the shower cap (thanks for pointing that out by the way) and this could easily be applied/removed in the water. The smoked version is perfect, reducing ambient light (vision) while allowing the diver to make out shapes. These are awesome! As I continued ranting about it, the other divers and instructors came over and also rallied about it. Within minutes, we were swarmed with divers interested in this. Your Guardian and Aga get beat up while working, storage shouldn't be a gauntlet of damage. This shield fits snug and hugs the clear portion of the mask, protecting it from scratches, gouges and those pesky gremlins. As soon as they dropped, I ordered 2 of the solid (for the wife's and mine) and a smoked for future training dives. These are one of those little things that make you say, "Wow, wish I'd thought of that!" Looking forward to using them as soon as they arrive.
