The Ratio iDive Dive Computer is available is a range of models to suit diver skills, qualifications and requirements. This comparison chart provides a quick reference between the features and specifications of each model.
The iDive Free is the entry model providing support for free diving and basic scuba diving with air or single mix nitrox diving. The iDive Easy adds an extra gas mix, enables real time algorithms and brings in compatibility with the Ratio Oxygen Analyser. The iDive Deep adds technical options with Trimix (normoxic) mixes and up to three gas mixes. The iDive Tech+ allows up to ten gas mixes and three diluents, adds a second algorithm, user settable gradient factor and critical bubble radius options.
Each of the iDive models has a corresponding Sport version that has the same features and functions of the standard iDive model but has a composite housing rather than stainless steel that is lighter, cheaper and comes in a range of colours.
