OX500

Up to 8 minutes. Time to really take it all in.

Light dancing on the sand. A school of fish drifting by. That detail you wish you could have watched a little longer. With the OX500, your short dives take on a whole new dimension.

Compact and light, this 0.5-liter tank combines the regulator and pressure gauge in a single unit, held directly in the mouth. Little to carry, and up to 8 minutes of stated air time to enjoy the world below the surface.

Stated air time; it varies with breathing, depth and exertion. The pressure gauge remains your reference during a well-prepared dive.

How does it work?

The OX500 combines a compressed-air supply, a regulator with a mouthpiece and a built-in pressure gauge. The regulator lets you breathe the air in the tank; the gauge shows the remaining pressure.

The tank can be refilled with the compatible manual pump, mini compressor or Power. The mini accepts AC or 12 V battery power; the more powerful Power refills faster and runs on AC only. US AC input voltage, frequency and plug are awaiting confirmation. After refilling, follow the checks in the user manual.
