Mares designed the new Sirius watch-style dive computer with the aim of perfectly combining technology and elegance. The characteristics of this dive computer feature top-of-the-range technology both for recreational and Extended Range divers. The recreational diver will see a simple screen, with the possibility of reading tank data thanks to the optional tank module. The Extended Range diver can insert up to five nitrox and trimix mixes to manage technical dives. The interchangeable strap allows the Extended Range diver to use any suit thickness. Its refined style makes the Sirius the perfect accessory, even out of the water. Available in black or black/silver versions.
