SeaLife ReefMaster RM-4K Underwater Camera and Housing

SeaLife SKU: SL350 | Helix SKU: SL350

Overview
 SeaLife has introduced the new ReefMaster RM-4K Ultra Compact Underwater Camera. Featuring a pocket-sized design with 14-megapixel Panasonic® CMOS image sensor and ultra-high definition 4K 30fps video, its ultra-compact,portable design ensures that divers and snorkelers can take the ReefMaster anywhere, from a wet environment to 130’ or 40 meters underwater. The camera captures sharp, colorful still images and brilliant 4K video with underwater color correction. The 140° Fisheye Lens allows a close approach to the subjects while still keeping everything in the picture.The unique ergonomic housing was especially designed for use underwater, while the housing is easy to hold and use even with one hand, the tough enclosure also features a unique closing system –a “Pressure Lock” thumb screw that exerts the optimal amount of pressure on the housings O-ring seal. The waterproof housing encases the small inner camera, and also stores a powerful drying agent called “Moisture Muncher” next to the camera that prevents internal fogging caused by heat and humidity trapped inside the housing.

Great!
Size: Medium, Color: Multicolored19-4 Pack
I have ordered three packages of these over the years. They are solidly made and withstand washing and drying without the color fading and elastic band stretching. They are sized correctly and are super comfortable.

Cute, colorful underpants
Size: Medium, Color: A-multicolored-4 Pack
Bought these for my fiance because his old (other brand) ones were getting very tired. The price was great and they are brightly colored, which I get a kick out of. These do not bunch up while he's sitting, moving around, or pulling up his pants, and are comfortable with pants with a snugger fit around the legs and pelvis. They are soft, breathable, and durable, and have withstood numerous washes without an inkling of fading, tearing, and wear. I had some difficulties with the shipping and the original order never arrived, but this was immediately resolved after one contact with customer service. They were very responsive and sent out a fresh batch minutes later, which arrived very quickly and without any issue. Overall, impressed with the quality of both the underpants and the customer service.

KIND OF BAGGY
Size: Large, Color: A-multicolored-4 Pack
I guess I'm not built quite like the guy in the photo. I found these to be a little baggy. I buy briefs because I don't want baggy. They were, however, comfortable enough. I liked the wider waist band and the elastic was fine. I wouldn't buy them again though.

Comfortable and secure
Size: Small, Color: Black Grey
Nice quality non fly men’s underwear. Pouch holds your gear firmly. Ordered small (30” waist) but ended up ordering same item in medium for more comfort. Also went with the cotton version.
