The Ratio iDive Tech is the top level model for open circuit diving and features support for up to eight gas mixes from a compact stainless steel watch style dive computer. The iDive Tech has a full dot-matrix display, rechargeable battery, a choice between two algorithms with either user settable Gradient Factor or Critical Bubble Radius settings and support for some pretty interested extra features.

The iDive Tech is an advanced technical dive computer packed into a small stainless steel casing. The full 80 x 80 pixel dot matrix display is protected by tough and scratch resistant sapphire glass and is depth rated to 220 m. The display allows information to be clearly shown on the screen in an easy to understand format and is particularly good for showing information in graphs or for using the built in digital self-compensating compass.

The computer features a double core algorithm that runs your choice or either  Buhlmann ZHL-16 B or   VPM-B in real time for truely complete calculations and very safe decompression profiles. The diver is able to customise each algorithm using Gradient Factors (Buhlmann) or Critical Bubble Radius (VPM).

The iDive computers use a rechargeable Li-ion battery which can be recharged from any USB source, whether it is via a mains adapter at home, a car adapter on the way to the dive, a computer port or a battery pack between dives. The battery provides up to 25 hours of diving use but extends its life in watch mode and will enter a sleep mode when no movement has been detected for five minutes.

The iDive Tech is supplied with a interface cable that allows it to be connected to a PC or Mac for data transfer to the DiveLogger software. It also allows firmware updates to be installed on the dive computer by the user.

The iDive is available in various models with more or less technical features to suit different types of diving. You can compare the different models on our Comparison page. The iDive Tech is also available in a number of finishes.
