The ATA Pro is a compact trimix analyzer offering oxygen, helium and balance gas readings in one box – the ideal all-in-one gas detection package for scuba divers

The ATA Pro is a compact trimix analyser offering oxygen, helium and balance gas readings in one compact box. With the ability to zero and span the helium sensor as well as oxygen compensation allowing for a more accurate helium reading the ATA Pro is designed to offer the highest levels of accuracy – something which is of utmost importance when pushing the boundaries of standard scuba diving.

Knowing your correct gas mix is invaluable when planning your dive. When exceeding the normal limits, having the incorrect gas mix can prove to be fatal.

The ATA Pro is a portable trimix analyzer which takes readings directly from your tank. Compact and lightweight, the ATA Pro can be easily carried wherever and whenever you dive.

As a diver, confidence in your mix means you can relax and enjoy your dive. Now you can check your tanks on the boat, making sure the tank you filled is the tank they hook up! The Analox ATA Pro is designed to be a major step forward in diver safety. Building on the success of the O2EII, the Analox ATA Pro retains the same qualities but with many additional features. There are many analysers on the market, many of which will give you an accurate read on your O2 and Helium... what sets the Analox ATA Pro apart is its absolute superior construction and design: drop it, kick it, bang it around, fish it out of the water, it will still give you the most accurate O2 read, be the most comfortable in your hand, and last far longer than any of its competitors. Analox value is in their quality.

Tech Tip

Trust No One

Get an analyser. Learn how to use it properly. Calibrate it before every use. The only person who should be analysing your cylinders is you. The only analyser you should use is yours.

Label Everything

Clearly label anything that isn't air. If the MOD is less than the maximum possible depth of the dive (think deco cylinders), make sure the MOD stands out where not only you can see it, so can your buddies. Make it obvious to everyone if you are using the wrong cylinder at the wrong depth.

Consider putting a small piece of tape on each second stage, just in front of the mouthpiece, that has the MOD for the cylinder it is attached to. (This is in addition to the standard cylinder markings.) Any little thing that may save your life helps.
