  • Description

    The iDive Free is a technical free diving computer with a compact watch style, advanced free diving functions as well as support for Air scuba diving, a full dot matrix display and a USB rechargeable battery, all with a great looking stainless steel casing and sapphire glass combination.

    The iDive Free is primarily a free diving computer but does also support scuba diving via a single 21% oxygen gas mix. The computer provides Taravana and Hemoptysis control which provides extra information and guidance to the diver during their free diving sessions to help keep then as safe as possible. On the scuba diving side the computer uses the tried and tested Buhlmann ZHL-16 B algorithm.

    The iDive Free is fitted with a 80 x 80 pixel dot matrix display that allows information to be displayed clearly and in a format that is easy to understand, even at a glance. The computer is powered by a USB rechargeable Li-ion battery that will take a charge from any USB source, whether it is a mains or car adapter, a computer port or battery pack so you will always be able to charge it wherever you are.

    The supplied interface cable also allows the dive computer to be connected to a PC or Mac  to download dive profile data for analysis and recording. There is also the ability to update the dive computer to the latest firmware version, eliminating the need to return the computer to a dealer for critical updates.

    Please visit our Comparison page for full specification details and to compare the iDive Free against the other iDive models. The computer is also available in a range of finishes.
