Questions and Answers for Aeris A300 Air / Nitrox Computer:

  • Tim:

    Hi, Are you an official dealer for Aeris? I would like to buy a computer but I want to get if from a dealer in case there are issues. Thanks

    Bill  (Certified Scuba Instructor at

    Yes we are authorized dealers for everything we sell.

  • Kayali:

    Transmetter is inclouded ?

    Bill  (Certified Scuba Instructor at

    This is NOT a air integrated computer.

  • Donna:

    Does the A300 have an automatic rest stop timer that turns on at 15 feet and a manual rest stop timer that you can turn on at 20 feet?

    Darrick  (Certified Scuba Instructor at

    Hello Donna, the answer to your question is yes. But with the 20' stop you would have to set-up that before you dive. Because you can set it to any depth.

  • Linda:

    The info tab says the A300 has wireless AI technology. Is the transmitter that must be connected to the 1st stage included with this computer? If not, how much do you sell the wireless transmitter for?

    Darrick  (Certified Scuba Instructor at

    Hello Linda, this is NOT a wireless unit. No sure where you see that stated? This computer will do everything on your dive but give you the air pressure from your tank. That you would still need a pressure gauge or another computer that does give you air pressure.

The AERIS A SERIES line of dive computers is poised to set a new design standard. The A300 is a sophisticated yet basic dive computer in a small, ergonomic wrist or console unit; packed with advanced fearures for even the most experienced divers, but also out-of-the-box simple for new or less frequent divers who want something they can grow into.

The A300 boasts a high resolution Tissue Loading bar graph which allows for at-a-glance feedback that lets you control your dive on the fly and regulate your dynamic conservative factor. The bright Green/Yellow/Red indicators make it easy to monitor your dive. It displays only essential information during the dive in large easy-to-read digits so you know how deep you are and how long you can stay there.

The A300 separates itself from the competition with the use of NORM and TECH modes. NORM mode is selected by default as an out-of-the-box solution that provides all the necessary settings and information for divers who just want to get in the water. When switched into TECH mode, advanced features and fine-tuning become available that will satisfy any experienced diver.

The 3-button interface allows for intuitive forward and backward navigation through a host of personal settings and options - and packs advanced features including Dual Algorithm® with Deep Stop, 2 Nitrox mixes to 100%, Audible Alarms, and Firmware Update (with optional interface cable) into a compact, rugged wrist computer.

Powered by Dual Algorithm® with Deep Stop
3 Operating Modes: Air/Nitrox, GAUGE (with run timer) and FREE (tracks calculations to allow switching between NORM and Free)
3 Operating Buttons with intuitive “Step Back” interface
Switch between up to 3 Nitrox mixes to 100% O2 with individual PO2 alarms
Single button access to “Last Dive” display
Audible Alarm with flashing LED light
SmartGlo® Backlighting
24 dive on-unit log book
Firmware Auto-Update with optional USB cable

Dual Algorithm Technology

Choose the one dive computer that’s liberal, conservative or middle-of-the-road.

Dual Algorithm™ technology lets you choose the decompression algorithm that best suits your diving needs without compromising safety.

Wireless Air Integration

Our Sophisticated Personal Dive Computers feature Wireless Air Integration technology.
A transmitter threaded into the first stage high-pressure port continuously sends cylinder pressure data to the dive computer. Frequencies are individually coded to allow multiple divers to swim side by side without interference with other units. Because the transmitter and display module are independent and separately powered units, the dive computer may also be easily used as a stand alone, non-air integrated dive computer.

Patented Air Time Remaining Algorithm

You're at 80 feet with 1300 psi remaining in your cylinder - how long before you need to begin an ascent to a shallower depth?
Our patented Air Time Remaining feature calculates your current depth, breathing rate, cylinder pressure, ascent time, and decompression status to tell you exactly how much time you can remain underwater.

Download and Settings Upload Interface

The PC Interface is an exquisitely detailed digital dive log. It allows you to easily transfer dive data from your Dive Computer to your PC via a plug-in USB cable.
Following download, your dive data is automatically formatted for easy viewing, sorting, analysis, and printing. Enter location, dive buddy and your notes and you've instantly created your own digital logbook. In addition to detailed dive analysis, the dive computer PC Interface also allows you to quickly and easily set most of your user settings and options through your PC.

Automatic Altitude Compensation

Selected Personal Dive Computers automatically compensate for altitude dives up to 14,000 feet, giving adjusted no-decompression times and depths.
Our Dive Computers even automatically recalibrates the depth displays for freshwater instead of seawater above 2,000 feet.
