However, the Smart Tec takes gas-integration to an entirely new level, allowing for up to three individual nitrox mixes to be programmed into the computer, and it can handle tank pressure information from up to three tanks fitted with transmitters.
This means that each mix can be monitored individually during the dive by pressing the tank activation button on top of the wrist unit and, like all Uwatec hoseless air-integrated computers, the computer and transmitters are paired permanently without risk of interference from other, nearby Smart computers.
The Smart Tec carries out several decompression calculations at once, giving credit for intended gas switches on the ascent, but also changing calculations if you fail to switch at the intended depth. If you switch late, it will re-adjust accordingly, and if you switch but then drop below the MoD of that particular mix, if will warn you of high ppO2.
The display is nice and clear, and every bit of information can be quickly and easily digested. The chunky strap is robust, and the whole unit has a feeling of durability about it. This is one smart computer and, while it costs a whopping £1,247 if you buy the computer and another two transmitters to go with the one in the box, it does virtually everything apart from buy you a bacon sarnie when you get out of the water!
Like the Smart Z, the Smart Tec comes in a hard plastic carry case, which includes a padded pouch for added protection.
