The Best Scuba Goggles The OTS Buddy Phone was designed as an easy to operate, one channel, ultrasonic transceiver. The state-of-the-art digital circuitry ensures excellent performance. A built in factor set squelch helps eliminate man made, or marine background noise. It operates on one single 9 volt battery giving you hours of operations. The push-to-talk control (PTT) allows for simple transmission and no false triggering. Range in good conditions can be out to 500 meters! The Closest We Have To Viz Piercing Goggles Is A Normal Mask With Night Vision Strapped On The Front, Not Quite X-Ray, But It's Getting There... OEDGCS Ocean Reef GSM G Divers Communication System If you need to talk underwater for your job, or maybe you just love to communicate underwater verbally then say no more (no pun intended), the underwater communication allows a great evolution of the diving activity and an outstanding improvement of the underwater instruction and education. Besides, the underwater communication is also making the diving activity safer and more enjoyable. Great range, push to talk button, activates when contacted with waterand uses a 9 Volt alkaline battery for power. The XSC Wide Angle Scuba Series is an Underwater Camera built into a dive mask making underwater photography "Hands Free" for safer swimming, snorkeling, and scuba diving. Photograph or video friends, family or fish. Connect camera to your computer with the USB cable provided. Download the images and video to your computer to email or print. 5.0MP images. Lever style buttons are easy to use with diving gloves. When choosing a snorkeling mask, your first and foremost criteria should always be a proper fit.  The rubber-like portion of the mask that makes contact with your face is called the skirt.  It’s purpose is to make a water tight seal against your skin.  A skirt that doesn’t properly seal against your face causes a host of problems like leaking, fogging, and fatigue.
A slow leak between the skirt of the mask and your face means you’ll have to constantly tread water to empty it out.  Treading water vertically takes much more energy than floating horizontally, tiring you quickly.
Lifting your mask away from your face to empty the water out will also make your mask fog.  When you pull your mask away from your face, new moist air enters the mask and condenses against the cold inside lens surface.  The more new air that’s introduced, the more moisture there will be to condense on your lens.
Never choose a mask solely because of the way it looks on the shelf or because someone told you it’s the “latest in mask technology".  Bottom line… be sure to find a properly fitting mask.
