Just got back from Cayman Brac. Purchsed the Aeris Manta shortly before a left. Used it the whole week and it worked great. Did the on-line training to set it up and learn how it worked. Very easy to understand and operate....and the price was right. Highly recommened.

Rating: Best dive watch ever!
Reviewer: Michelle F.
This computer is amazing, plus the price is right. It is great underwater, tells me what I need to know. Has the option to be conservative or not, and can be set to your specifications if you want to personalize it. The computer is very durable, it is thrown around all over the boat, in my bag, in the sand and still looks brad new. I recommend it to anyone who is in the market for a dive computer, its just an added bonus that it is inexpensive.

Rating: Aeris Manta air/nitrox watch computer
Reviewer: Michael E.
I bought this because I wanted a dive computer that I could wear as a watch during dive vacations. The Manta is slightly larger than a regular watch, but still small enough to wear every day on a week long trip. I replaced the standard band with a velcro sport band. The standard band, with its extra length extender, adds potential failure points. It took a little while to get used to navigating through the screens and set up options, but once familiar, it was pretty easy going. INstructions were clear and easy to follow. I like how easy the unit is to read underwater and the integrated light, especially for night diving. I did get a low battery warning the second day I used the unit. I found out later that false battery low indicators can be somewhat common with this unit. The error cleared itself and didnt return. I always have spare batteries in my dive kit anyway, and the battery is easily changed by the user when needed. I dont like that the watch doesnt give average depth unless you send your dive data to your pc. I also dont like that you cant go backwards in screens/dives when reviewing the dive log. If you accidentally pass the screen you want, you have to go all the way around or exit the log and get back in, which can be quite a few button pushes if the 24 dive on board log is full. These are pretty minor gripes, though. For the price of the Manta, its hard to find a full function nitrox computer that also works as a watch. I considered the Suuto, but I didnt like how conservative the algorythms are, the Aeris fits my style of diving better. So, overall, I am happy with my purchase and would recommend this computer to others. There are deals to be had since the cosmetics have recently been changed (along with its sister computer, the Oceanic Geo,) so if you dont need the newest styling, consider looking for an old model at a good discount.

Shipment arrived as planned from I bought two of this computers for our planned trip in Oct. The computers come in "sleep" mode from the factory which causes the batteries to last for "7 years." I decided not to wake them up yet...

Rating: Great Dive Computer
Reviewer: Mitchell Levine  -  View all my reviews
The Aeris Manta computer was easy to use. I entered any changes in the default settings on my laptop and transfered the information to the dive computer with the sync cable. The watch is small enough to be used as a regular watch during a week of diving. I doubt I will ever do free diving, but thats my loss. As for this item, I recommend it.

Questions and Answers for Aeris Manta Air / Nitrox Computer Watch:

  • bob:

    can you set this watch to a certain gas mix and not have it go back to default? In other words can you set it to a gas blend and have it stay there until you reset it? thanks, bob

    Bob  (Certified Scuba Instructor at

    No. The computer is designed to always default to air.

  • paula:

    What type of battery does this computer use? can you buy it off the shelf?

    Bob  (Certified Scuba Instructor at

    Yes, this computer uses a common watch-style battery that is easily obtained. You can also purchase it on our site from the computer accessories page.

  • paula:

    Can a spanish version of this computer be bought?

    Bob  (Certified Scuba Instructor at

    Is this Mac-compatible?

    Darrick  (Certified Scuba Instructor at

    Hello Sheilagh, no this is not a MAC friendly computer. If you are looking for one take a look at the TUSA Zen Air / Nitrox Computer Dive Watch web link: If you would like to place an order order have any other questions please feel free to give us a call at 1.800.347.2822.

  • louise:

    What capability does the dive download kit add? Is it just record-keeping for a series of dives or ???

    Bob  (Certified Scuba Instructor at

    It does not add any exra capability to the computer. It is simply a dive log book that is downloadable to your computer.

  • Grant:

    Does this computer come with a transmitter? I did not see it listed. Thank you

    Bill  (Certified Scuba Instructor at

    No this is not an air integrated computer.

  • Mike:

    Does it come with a compass? Does it work at all angles that you can hold your watch? Does it have automatic warnings (audio/visual)for safety stops/decomp?

    Darrick  (Certified Scuba Instructor at

    Hello Mike, no this computer does not have a compass built into the watch. It does have both audible and visual alarms with user acknowledgment.

Advanced Free Dive Mode
The Manta provides accurate depth and time with an amazing 1-second sampling rate for subsequent PC download and analysis. Dive Time is displayed in seconds and minutes. Custom audible alarms include Elapsed Dive Time, Countdown Timer and (3) Independent Max Depth Alarms. The Manta is the first Free Diving Computer to calculate and track Nitrogen Tissue Loading, allowing you to switch between SCUBA dives and Free Dives on the same dive day.

Advanced Wristwatch Functions
The Manta is an advanced digital wristwatch featuring a 1/100 second chronograph (stopwatch) with lap timer, 24 hour countdown timer, daily alarm, alternate time zone with date, 12/24 hour clock, and OceanGlo® Backlight.

Dive Time Remaining
Dive Time Remaining provides a 'real' number in minutes, considering Nitrogen and Oxygen absorption, and automatically displays whichever allows less time.

Oversized Digits
Take the AERIS challenge: When shopping for a new dive computer, compare the displays. When it comes to viewing critical information, which would you rather see at 100 feet?

Audible Alarms with Flashing LED Warning Light
The Manta features a variety of system and user-customized audible alarms, alerting you to situations that pose a potential danger, or simply serve as a convenient reminder.

Audible Alarm Acknowledgement™
Have you ever had difficulty hearing your computer's audible alarm? Perhaps that little beep signifying a potentially dangerous situation was timed perfectly with your exhaust bubbles rushing past your ears. Or maybe it seemed insignificant as that huge manta ray soared overhead. You won't miss the Manta's audible alarm. Once triggered, the alarm will sound continuously for 10 seconds. We know what you're thinking. 'That's nice, I'll definitely hear the alarm, but isn't that going to annoy me and everyone else in the water?' We thought of that too. The alarm's job is to get your attention so that you look at the computer. Once it does that, simply press the button and it will stop. You're a responsible diver and the Manta treats you that way.

Air or Nitrox
The Manta acts simply as an 'Air' computer until you tell it otherwise, whether that is this weekend or 2 years down the road.

AERIS Personal Dive Computer Algorithm
Decompression theory can be trusted only as far as it has been demonstrated by actual test dive data. In 1987 a unique series of experiments were conducted by Diving Science and Technology (DSAT). Commissioned by the Professional Association of Diving Instructors (PADI), these Doppler ultrasound monitored human experiments conducted by Dr. Michael Powell produced the most comprehensive data set that exists for recreational divers to this day. These data were used to validate the PADI Recreational Dive Planner and are the basis of the algorithm used in all AERIS Personal Dive Computers (PDCs).

Personal Conservative Factor Adjustment
When the Conservative Factor is set On, the no-decompression limit times are reduced to values equivalent to those that would be available at the next higher 3000 foot (915 meter) altitude.

'The Ultimate Adjustable Algorithm'
That's the way divers, instructors and Authorized Dealers refer to AERIS PDCs. Our tissue loading bar graphs provide complete control of your margin of safety for each dive. Want to be a bit more cautious? Make it a personal rule to never enter into the caution zone; or stay one or more pixel away. Now you can even program several of our PDCs to do it for you with our patent pending Nitrogen Bar Graph Alarm; set it once and let the Manta alert you when your bar graph reaches that level.

No Deco Safety Stop Prompt with Adjustable Depth and Time
An audible and visual alarm remind you as you approach your programmed no decompression safety stop depth and an automatic timer counts down to zero. As in any other dive mode, you still have access to other pieces of information, and there is no penalty should you choose to disregard the safety stop.

FastSet User Interface
Speed through menu items and set modes easily and quickly with AERIS' FastSet Menu and intuitive button operation.

Date and Time Stamp
The Manta features time of day on the surface as well as underwater for quick reference. Time and date stamp also helps you to easily identify specific dives in Log Mode or PC download memory.

Alphanumeric Display
An alphanumeric 'Message Box' is incorporated in the upper portion of the Manta display to provide text and numeric readouts in simple, unambiguous terms. Imagine beginning an ascent and as the ascent speed increases hearing a warning beep from the Manta as the message box alerts with the words 'TOO FAST' while the red LED warning light flashes.

Automatic Altitude Compensation
The Manta automatically compensates for altitude dives up to 14,000 feet, giving adjusted no-decompression times and depths. The Manta even automatically recalibrates the depth displays for freshwater instead of seawater above 2,000 feet.

Diver-Replaceable Battery
The Manta features a diver replaceable battery. This can be a real trip-saver on board a live-aboard boat!

Battery Hot Swap
Should you be in a tight spot between dives, the 'hot-swap' feature allows you to change batteries between dives while maintaining all calculations.
