About Mares Icon HD Air Integrated Hoseless Computer, Wrist Unit

Incredible Color, High Definition Dive Computer

Introducing the all-new Icon HD to the market, Mares is bringing state-of-the-art consumer electronics technology to the underwater world. Flat screen televisions, cell phones, PDAs, notebook computers, all use an LCD display, the same technology that Mares is using for the Icon HD screen. ICON HD is a True full-color mineral glass display computer. Its screen is made using LCD (Liquid Crystal Display) with TFT (Thin Film Transistor) technology.

The new Mares Icon HD uses Mares-Wienke RGBM (Reduced Gradient Bubbles Model) algorithm. The RGBM takes into account the phenomenon of micro-bubbles in order to prevent their formation. In over 10,000 real dives monitored by Dr Bruce Wienke in the Los Alamos laboratories, the formation of micro-bubbles has been studied and evaluated in order to better understand the mechanism behind how micro-bubbles are formed during a dive. Today it is the most evolved algorithm for reducing the formation of micro-bubbles without compromising dive times.

An intuitive software, the use of large characters, and the contrast created by using different colors, makes the on screen information easy to read, immediate and clear. During the dive besides the standard navigation mode EXTEND, divers can switch to a second dive mode PROFILE ICON HD processes and shows the full dive curve in real time. The computer's memory allows the storage of images and photos, including digital maps of diving spots.

The easy excess push buttons allow the diver to operate the computer in all conditions, even when wearing thick gloves. Navigating through the computer programs is extremely simple and very intuitive. The Icon has a maximum depth display of 492' (150 meter), a memory capacity of 100 hours, runs on a user replaceable rechargeable lithium battery, power indicator, has a plan mode display, can be used in both imperial or metric units, fresh or seawater settings, residual nitrogen reset, option to exclude audible alarms and uncontrolled ascents", has an ascent rate indicators, and is altitude adjustable.

A gas switch function allows divers to use up to three different gas mixtures during a single dive. The computer calculates the decompression schedule accordingly, so that you can take full advantage of decompressing with high oxygen concentration mixes. Integrated interface: a reprogrammable processor with a rewritable chip for software upgrades. The dive computer software is upgradeable. As Mares continues to introduce new features and functions to its computers, you can benefit from these improvements without needing to buy a new product: simply download the new software release from the Mares website and install it into your existing computer using the dedicated interface.

The Icon HD knows that not all of us who dive are young and in peak condition, it address this with precautionary program settings that allow individual adjustment to more conservative dive profiles if needed. When you do multi-level, multiple dives during a single day or multiple dives over several days you can choose different setting levels in order to adjust your computer to a more conservative dive profile. The Icon also has a digital compass function for navigation. The compass mode can be activated both on the surface and during a dive. Both on the surface and during the dive, divers can also make use of the sighting function so that the compass will show the selected direction.

Air Integrated computerized monitoring of tank pressure is used to determine a bottom time which depends not only on your depth, but also on your actual gas consumption, increasing your dive safety. In addition, the gas consumption (referred to the surface) is displayed on the computer for more control over your dive. The computer does this via a HP Transmitter (optional see SKU: MRSIHT) attached to your first stage regulator HP port by sampling the pressure drop over time and giving you the rate of consumption in minutes remaining. If the time remaining is greater than the no-decompression limit for your depth it will display the shorter time allowed.

The combination with icon's high definition color display brings tank pressure information to a new level. Detailed numerical information is accompanied by intuitive, at-a-glance color coding. Blue and green means the pressure is above the mid tank warning, red means the pressure is below the reserve, orange and yellow for values in-between. The thresholds are set by the user for maximum customization.

The Icon HD comes with a PC interface for logging dives on your PC; the computer is also software upgradeable over the internet. This feature makes it possible to download the latest software developments as Mares creates them, without the need to buy a new computer unit Icon also has a watch, date and temperature functions. Smart, easy to use and upgradeable the Icon HD can do it all.

A user info screen allows you to save your personal information, such as full name telephone number, blood type, any allergies and any other important information you want to have with you. Special characteristics: nitrox mode with 3 different oxygen mixes, integrated interface, rechargeable lithium batteries, map function, pictures function. Icon HD comes with a free padded bag, User Manual and has a 24 month limited warranty.

Dynamite Graphics, easy to use, but...

Let me be honest. I own a Galileo and I wouldn't trade it for an Icon HD. Two staff members of our LDS bought the Icon and I got to use it for 4 dives. Within the limits that I feel the computer has...I think it is a fantastic piece of equipment. There are certain features that I wish my Galileo had. Pros: - The "3D" display is very bright, very easy to read and really well organized. - The operation is very intuitive. - The unit is very comfortable to wear "the same size and feel as m...

Not reliable

Computer worked great for the first 5 dives, then the problems started. At first I was having problems charging the unit (which by the way you have to do pretty much every day you are diving). The charging problem was resolved by changing the USB cable. Then started having problems pairing transmitter to the computer. In the middle of the dive I lost the integration, good thing I had the regular console to see my air. After multiple attempts to pair the unit to the transmitter and failing, ...

Makes diving effortless


from Columbia, SC, US

My wife and I LOVE this computer. Worth every penny. Everyone we meet who has one raves about it. Everyone else asks about it. Would buy again in a heartbeat. Very easy to use. Battery lasts much longer than expected, both with diving and in standby.


Excellent computer


from Chicago, IL, US

In my opinion, you'd be hard-pressed to find a similar quality computer at this price point. Mine came air integrated and I've put about 100 dives on it. No issues with loss of signal between transmitter and the computer. Very easy to read and intuitive interface. Only downside is that the beautiful screen is beautiful because it is big and bright -- both of which are battery hogs. So you're only going to get 2-3 hours of diving on it beore needing a charge. So if you're good about remembering to do that, then I think this device would be a great buy. -Yosef


It look really good


Delivery was on time,Great Service




Beautiful and easy display but my biggest gripe is the RGBM algorithym is way to conservative. I know, i'm complaining about being TOO SAFE. When I'm spearfishing/lobstering with friends I frequently get knocked into deco 10-15 minutes before my buddies diving on the same percentage nitrox. I have the computer set to the lowest setting and it is still crazy conservative. It is a very reliable computer but I will be looking to replace it for something more liberal soon, like an oceanic.


I would buy tihis computer again


Nice equipment, ligtht weigth and great color monitor
