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.

Comments about Aeris Aeris Manta Scuba and Free Diving Wrist Computer "Old Style":
I got this Computer in time for my first dive trip of the year. It is my first computer, and while playing around with it before my trip, I thought it might be too complicated. I was wrong.
Once I got the settings figured out (much easier to manipulate if you have the PC Download Cable and Aeris Software) and set it to "WET" (automatically goes into Normal Dive mode when you go below 5 feet - I think)it was a piece of cake to read and understand.
Downloading the dives was fairly easy too, though the software is kind of goofy. I love the info and graphs it provides. Beacuse it's not integrated, you can still put in your Starting and Ending PSI.
I have it set pretty conservatively, so I got quite a few warnings (Depth, High NI, Accent Rate). The alarm is not as noticiable underwater as they claim, but if you are keeping an eye on your depth and time, it will get your attention.
I also made the mistake of wearing it once when I was snorkling. I dove down, and with it being set to "WET" it counted it as a dive.
The computer I received did not look like the picture on LeisurePro's website: The Face and straps are blue while the main part is white. I'm not complaining, I love it, I think it's actually easier to keep track of than if it had been all black.
