AV1 Classic OPEN CIRCUIT TRIMIX DIVE COMPUTERS

The AV1 Classic is a full-feutered expedition grade computer. Almost all function are customizable. The computer use OC/CC Buhlmann ZHL-16C with gradient factors. 8 gases Air, Nitrox, and Trimix ,with integrated compass, planners, and game. Our unique dynamic ceiling bar-graph helps diver to maintain precisely his decompression stops with one look. That make the decompression procedure more easy, increase the safety, and gives diver a critical support in emergency situations.

"This simple and reliable computer with classic looks quickly became my essential diving tool for training technical divers worldwide." – Michail Balabanov, PADI Trimix Instructor Trainer

AV1 Classic OPEN CIRCUIT TRIMIX DIVE COMPUTERS

There are several options: version without frame and version with protective bezel. Every unit body can be made from Delrin or deep anodized marine-grade aluminum, with or without bezel. The bezel is also available in Delrin or aluminum.

Delrin bezel colors: black, blue, and yellow.
Aluminum bezel colors: black, blue, yellow, red, and pink.
The Delrin version without bezel is our lightest and most affordable option.
The full aluminum version with colored bezel is a heavier and premium priced option.

Overview

WHICH AV1 OC IS RIGHT FOR YOU? Choose AV1 Classic if you want the lightest computer at the best price. The AV1 Classic framed if you need extra durability for extreme conditions. Both models offer identical diving capabilities.

ENHANCED DURABILITY. REFINED PERFORMANCE. The evolved AV1 with improved frame durability. Same features as Classic Old, built stronger for the most demanding technical dives. The perfect balance of performance and value.

THE ORIGINAL. LIGHTEST. MOST AFFORDABLE. The original AV1 Classic non-frame design trimix dive computer. Trusted by technical divers worldwide for over a decade. The lightest model in our lineup at the most accessible price point.

GRAPHIC

Precise Graphic of the diver's performance, ceiling and temperature changes during the entire dive.

TABLES

AV1 recording every 10 seconds of the dive performance a great tool for the Instructors and demand divers.

SURFACE SCREEN

All info you need at surface, as well as dynamic graphic of 16 tissue saturation.

DECO PLAN

At any moment of the dive the whole dive plan with all the forthcoming decompression stops can be looked through.

VIOLATION WARNINGS

Violation warnings: deco, PO2 level, not-best gas mix, high ascending speed, high CNS, etc.

AV1 TEC MODE SCREEN 1

During decompression AV1 has an indicator of so-called «dynamic ceiling» that allows to have both step-by-step and «uninterrupted» decompression.

AV1 TEC MODE SCREEN 2

At any moment of the dive the whole dive plan with all the forthcoming decompression stops can be looked through.

MULTI-LEVEL DIVE PLANNER

Tech Specification

AV1-RCD dual power controller. It's the same proven controller as AV1-RC, with one important addition: a built-in container that accommodates one additional 18650 battery. This allows the controller to operate completely independently from any external power supply from the rebreather.

The standard rechargeable battery in the main body provides backup power, giving you two independent power sources in a single unit.

IMPORTANT NOTE: The AV1-RCD provides less total working time compared to our complete system, which uses one standard battery in the computer body plus two external battery containers built into the rebreather head. The AV1-RCD is our optional standalone model, available on request.
