Mark Evans: Dive computers from Aqua Lung just keep on coming, and the Aqua Lung i200C represents fantastic value for money for a well-equipped and durable wristwatch-style unit.
It uses the tried-and-tested Z+ algorithm, and has a segmented LCD display, which is easy to read – for low-light conditions, it has a push-button-activated back light, which is handy on night dives.
It has got four operating modes – Air, Nitrox, Gauge (with run timer) and Free Dive. Handily, the latter tracks calculations to allow unrestricted switching between free and dive modes.
In Nitrox mode, it can handle two gas mixes, up to 100 percent oxygen, so will cover the vast majority of divers for all of the diving they will ever want to do.
It has a user-replaceable battery, so no sending it off to the manufacturer when it runs low, which is a bonus with a wristwatch unit, as many people will use this as a day-to-day watch.
It comes in six funky colours, from the more-subtle Grey and Dark Grey to in-your-face Bright Pink, Aqua, Blue, and Hot Lime, and in the box you get the unit itself, plus a lens protector and a battery compartment opening tool.
We tried out the Hot Lime, and it certainly stands out as a daily wear watch, often eliciting comments from even non-divers. It feels solid on your wrist, but is not what I’d call heavy. The best thing about the i200C is how easy it is to use – it literally takes a couple of minutes to get your head around the menu and navigation and then you are away. I let several of the Deptherapy divers have a trial dive with it in Egypt a couple of months ago, and they were all happily using it within a short time. It was also brought out for Ryan Arnold to use when he was doing his entry-level RAID course.
However, one of the i200C’s greatest attributes is down to how well it works with the DiverLog+ app (which is available for iOS and Android). The i200C seamlessly interacts wirelessly via Bluetooth Smart technology, and you can control all aspects of the computer from your phone or computer. I found it easy to jump into DiverLog+ and adjust all the settings – gas mix, salt or fresh water, alarms, etc – and then it is a simple matter to just fire that over to the i200C and, you are ready to dive. Far quicker and easier than doing it all manually on the computer itself, to be honest.
On completing your dive, you can then throw over all your dive data from the i200C into your DiverLog+ app logbook. Your dive profile, time and date, water temperature, etc, are all brought over from the i200C, and you can then add additional information, such as what gear you were using, your location, buddy’s name, any photographs or videos you took, and so on. You can even get your buddy to digital ‘sign’ your logbook. Once complete, you just hit the ‘share’ button and can send it out via all the usual channels – email, Facebook, Messenger, Instagram, etc.
The DiverLog+ app has many features beyond those described above – you can build up a file of buddies, locations, ‘gear bags’ for different conditions, and much more. Like the i200C itself, it is very intuitive and easy to use.
With a decent range of capabilities, and coming in at just a shade under £300, it represents excellent value for money and is a nice user-friendly piece of kit, especially as it works so well with the DiverLog+ app.
