After more than 40 years of leadership in the SCUBA industry Bob Hollis has decided to step down as CEO of Oceanic, AERIS, LavaCore & Oceanpro but remain Chairman of the Board of AUP.
The MANTA is a powerful and versatile new sports watch, ideal for divers, free divers and those that just want to look like one. A unique combination of quality, function and style, the MANTA is perfect on its own or as a backup to any of our other Dive Computer models.
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.
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 provides a 'real' number in minutes, considering Nitrogen and Oxygen absorption, and automatically displays whichever allows less time.
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?
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.
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.
The Manta acts simply as an 'Air' computer until you tell it otherwise, whether that is this weekend or 2 years down the road.
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).
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.
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.
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.
Speed through menu items and set modes easily and quickly with AERIS' FastSet Menu and intuitive button operation.
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.
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.
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.
The Manta features a diver replaceable battery. This can be a real trip-saver on board a live-aboard boat!
Should you be in a tight spot between dives, the "hot-swap" feature allows you to change batteries between dives while maintaining all calculations.
