Scuba diving relies heavily on equipment to support your life in a submerged environment. One piece of gear we need when exploring is a dive computer. Normally these look like a large wrist watch and display essential information such as your depth, the time elapsed during your dive, your No Decompression Limit (how long you can stay at a given depth), and a few other bits such as time, and water temperature.
We now use a new dive computer called the NERD 2 by Shearwater Research. It's a heads up display that shows all your information in your line of sight by way of a device that mounts to your regulator hose. In the image above you can see Trisha; her right eye has a cylinder looking device there, this is the NERD 2. It's a brand new piece of high end dive gear that is perfect for people shooting video underwater.
With a glance of the eye, you can look at the NERD 2 and see all your dive information. This is excellent for shooters like us, we don't have to move our wrist. Whaaat - how hard can it be to move your wrist?! Well, if you're filming a cool marine life encounter, the last thing you want to do is move your arm, wrist, and camera and spoil the shot. The NERD 2 puts your essential dive info right in front of you, so you don't have to move or risk messing up a shot, but you can stay safe and informed.
It's an amazing piece of gear, check out this link to learn more.
