Aeris recently announced its new MANTA Wristwatch Dive Computer. Compact and kinda stylish, the water-activated MANTA is air- and Nitrox-compatible and also features special modes for freediving.
Offering backlighting, an alphanumeric display, and a user-replaceable battery, the MANTA comes with a Wrist Band Extender, a battery and battery hatch tool, and ACI PC Interface CD-ROM. (Diverwire even boasts that the MANTA comes with an operating manual. Wow-ee!) Optional accessories include color-coordinated Sport Wristbands and an ACI PC Interface USB Cable. The MANTA retails for $430.
