The Suunto D9 dive computer is a model that should be considered when you are looking for quality scuba diving equipment. We hope to give you useful information to make an informed decision before purchasing a divers computer, but the D9 offers some superior features and functions to your basic models. In fact, it is touted as the world’s first all-in-one diving computer. Pricing will exceed at around a thousand dollars and in fact is closer to the two thousand dollar range, depending on options and where you purchase, but it is rated as a superior computer, compared to others in the same price range.

All-Round Functioning

The Suunto dive computer D9 can be worn as a watch above water at any time or any occasion. However, when underwater, it provides all the gauges which allow you to log time, depth, temperature, and no-decompression limits over many divers. You can switch between metric and imperial units and between free and gauge diving. Its digital compass can store multiple headings, unlike most regular compasses, making it easier to put together maps. This dive computer contains so many features which makes it superior to other dive computers that are around.

The capability to handle three gas mixes makes the D9 good for deep technical dives. Divers using the D9 computer have the ability to switch between 3 gases during their dives, using gases with anywhere between 20 and 100 percent oxygen. Able to be used at depths up to 660 feet (200 meters), the D9′s Deep Stop RGBM lets the wearer add safety stops to allow for safe gas switches. Testing proves the D9 both capable and reliable after even hundreds of dives.

Wireless Transmitter and Dive Logging

You can connect the optional wireless transmitter to the first stage regulator, which converts the D9 into an SPG. For instructors, you can use multiple transmitters to monitor the pressure of more than one tank, which is helpful, as long as students remember to activate it before the dive starts, because otherwise, you have to return to the surface to activate it. The USB interface and PC software that comes with the D9 divers computer allows your dives to be easily logged and gives you a complete dive profile because it can store all of the pertinent data, including photos from the dive. This is interesting to compile information from individual dives, including the sites, conditions and any other information you may want to store as notes.

What More to Keep in Mind

The only real drawbacks we found with the Suunto D9 software is that it will not work with Mac systems and the need for an expensive battery replacement which requires it to be returned to the service center or an optional wireless transmitter feature, must be activated on the surface. As a whole, this dive computer supplies deep divers with any thing they could possible need in a wristwatch style computer. The all-in-one features are perfect for deep dives and technical dives. You should consider the D9 if you are seeking a superior option for dive computers.
