This computer offers a wide range of dive modes, from standard Air and Nitrox to Freediving, allowing them to explore different disciplines with a single device. Features like the integrated compass, altimeter, alarm functions, and a rechargeable battery with up to 20 hours of dive time provide the versatility and safety they need as they advance their hobby.

Competitive features

When choosing a dive computer, key factors include display clarity, supported dive modes, and durability. The Ratio iDive Color Tech+ enters the market as a robust, feature-rich option designed for serious divers. It stands out with its high-contrast color display for excellent underwater readability and a durable build featuring stainless steel and sapphire glass. We've compared it against other popular models like the Scubapro Galileo 3 Ti and Suunto Eon Core to see how its features stack up for different types of divers.

Where it excels

The iDive Color Tech+ offers extensive multi-gas support, including Air, Nitrox, Trimix, and CCR modes, making it highly versatile for technical divers. It can monitor up to 10 wireless transmitters and features a dedicated SideMount mode. Its construction is exceptionally rugged, utilizing a fully armored stainless steel body and sapphire glass for the display, engineered to withstand demanding underwater conditions. A unique integrated feature is its ability to connect with a Nitrox analyzer for professional gas analysis, a function not commonly found in competing wrist-sized dive computers. The user interface is icon-based on a 1.3-inch color display, designed for intuitive navigation and customization, with full deco tables displayed during the dive.

Consider alternatives if...

While the iDive Color Tech+ is packed with advanced capabilities, casual divers who only need basic functions for occasional trips might find its extensive feature set, such as Trimix and CCR support, to be more than they require. A simpler, more streamlined device could be a better fit for their needs. Divers who prioritize a specific brand ecosystem or user interface they are already familiar with, such as those from Suunto or Garmin, might prefer to stick with those brands for a consistent user experience across their gear.

Verdict

The Ratio iDive Color Tech+ is a powerful and durable dive computer that excels in versatility and readability. With support for multiple gas mixes including Trimix and CCR, wireless air integration for up to 10 transmitters, and a rugged build, it's a compelling choice for technical and professional divers. Its high-contrast color screen and intuitive interface are significant advantages. While it may be over-specified for a casual recreational diver, its combination of advanced features and robust construction makes it a strong contender in its category.
