The Explorer II Folder bag solves the problem of storing a jumbo travel bag when it's not in use. When you're ready for travel, it measures 33 by 17 by 17 inches, but with its internal frame folded, the Explorer II is only 3 inches tall. The bag's telescoping handle and all-terrain wheels make it easy to transport when loaded with gear.

The front “u” shaped pocket has a double-zipper and features a padded compartment for your tablet or up to a 17-inch laptop. The interior has zippered mesh compartments for additional storage and a vertical-zip front-facing pocket and elastic side-pockets for additional accessories. Padded shoulders pads feature an adjustable sternum strap.

Rugged coated fabric, heavy reinforcement at wear points, stout wheels and telescoping handle make the Piper a carry-on that can handle plenty of tough dive travel. The zipper opens wide to allow easy access to the roomy interior, which features mesh pockets for additional organization and security. A handy external pocket provides quick, on-the-go access to smaller items.

This two-bag system allows you to transport wet gear in the same backpack as dry gear while keeping them isolated from each other. The main compartment is made of rubberized mesh, and the removable drybag is completely watertight. Two external mesh pockets with nylon straps are perfect for storing a pair of fins.

A large screen with bold data digits organized on a high-contrast display makes for easy reading of important depth, bottom time and gas information. Built to stand up to the harshest dive conditions, the unit automatically activates when connected to the tank. The depth gauge reads to 394 feet (120 meters); gas pressure to 4,351 psi (300 bar).

Built of chrome-plated brass, this pressure-and-depth gauge displays both metric and imperial readings so you can always understand how much gas you have. Pressure gauge reads up to 5,000 psi (350 bar) and depth gauge goes to 230 feet (70 meters). The gauges have luminescent faces and are seated in a textured rubber boot.
