Sure, you can kill an afternoon quickly by simply putting your pole in the water, cracking open a beer, and hoping that you get a bite. But if you're on the water to actually catch fish, it helps to know where they are. Fish Hunter Sonar can tell you. Powered by military-grade sonar technology, this ingenious device is so small it floats, and pairs with a smartphone app that allows you to see where the action is, even while the device itself is up to 80 feet away.
Hunters, boaters, cops, and military personnel will find plenty to like about about the Celestron Cavalry GPS Binoculars. Outfitted with an integrated GPS, a digital compass, and a reticle, determining the direction of and distance to objects has never been easier. Rugged construction means these binoculars can handle the elements, as well as plenty of rough treatment — thanks to waterproof construction, a rubber armored exterior, and nitrogen purging to prevent lens fog, while the olive drab color helps it blend in. A built-in LCD provides lots of useful data, including your coordinates, altitude, and a compass readout.
Snorkeling is a great way to take in the sights and sounds under the sea without the need for bulky scuba equipment or certification. But it does have one big drawback: you either get used to breathing solely through your mouth, and keeping your head high enough that no water comes in, or you deal with water in your mouth and fogged up goggles. Unless you're wearing the Easybreath Snorkeling Mask. This revolutionary mask fits over your entire face, allowing you to breathe normally underwater without fear of fog, and features a dry-top system on the top that plugs the air intake when immersed, preventing water from entering.
