Color, color. For a Mistral with no tabs, what the difference? Maybe pink to match fins? Can't wait to try. By using a clear silicone, the diaphrams will be very easy to id. But seeing as how it is behind my head, I guess I will have to bring the trusty Agua Krafto rear view mirror:
AGUA-KRAFTO
New from Agua-Krafto is the ultimate in knowing where your stupid dive buddy is. Now you don’t have to spend all your bottom time looking for the idiot. Just hold up your new technology Agua-Krafto rear view mirror and see him struggling to keep up. If he is out of your vision, oh well. His job is to stay with you, not vice versa.
Made of modern materials the Aqua-Krafto rear-view mirror will last its lifetime (TBD) and full guaranteed to work both above and below water (TBD).
Now you have the state-of-the-art product to show those guys at Portage Quarry that you are up-to-date.
Instructions:
Put the rear-view mirror on your wrist with the attached Velcro attached strap. Duh put it so you can see in it. Hold the sucker up away from your face and look into it. It even works. Enjoy another quality dive accessory from AGUA KRAFTO.
