Product Information
This package pairs the Mares Dual 15X Regulator with a matching Mares Dual Octo Regulator, giving you a complete first stage, second stage, and backup breathing setup in one order. The Dual 15X first stage is built from Ultralight Technopolymer with a balanced diaphragm design and an ACT valve, and it drives a compact 183 g second stage through a 75 cm Superflex hose for flexible reach. The Dual Octo shares the same ultralight technopolymer construction and Superflex hose, and adds Mares' Vortex Assisted Design (VAD) with Pneumatic-Assisted Design (P.A.D.) for easy breathing at depth as a backup second stage for a buddy or a training dive.
The Mares Quad Ci Color dive computer rounds out the bundle with air, nitrox, and trimix modes built on the Bühlmann ZH-L16C algorithm with customizable gradient factors, shown on an 8-color high-resolution MIP display. It reads hoseless tank data from up to five transmitters, tracks tank pressure and saturation with color-coded readouts, and logs up to 100 hours of dive profiles at a 5-second sampling rate. A full-tilt digital compass, a decompression planner with a surface interval function, and a Time To Reserve indicator are built in, and the unit recharges via clip and USB cable for up to 500 cycles.
Completing the setup is the Mares Instrument LED Tank Module 2.0 in Black/Black, which transmits tank information and gives a color LED readout for a quick surface check before you gear up. It is EN250:2014 certified to 300 bar, uses permanent pairing, and runs on a user-replaceable 14250 battery rated for 150+ dives. Together, these four pieces bring a regulator, octopus, dive computer, and tank transmitter from a single brand into one order.
