Clear Information Layout is easy to read and understand what the computer is trying to tell you without over-complicating the information. Dual button interface is intuitive and easy to use to cycle through information during the dive.

Each of the three sections are dedicated to one aspect of your diving so you can understand the information based on where it is on the screen. Depth information is always on the top, current depth max depth is always in the top section.

Decompression info is always in the central section and auxiliary information stays in the bottom section.

9 December 2015

Price quality great for a watch/dive computer you can wear all holiday.

18 August 2016

Need the strap extension to wear over a wetsuit or glove.

19 April 2017

Excellent gift for my wife she loves it Easy to use, but should come with strap extension

I am a dive instructor, and have been using a Oceanic Geo for the last 5 years. I just bought the Mares smart wrist computer and I can say I am truly disappointed. It has no history other than your 34 dive memory, no history of hours logged no tissue

21 July 2017

This is my first dive computer. I love it. So easy to use and understand. The first time I wore it was for my PADI Advanced Open Water Diver.

She has just started diving and this is her first computer. It provides all the functions she needs (and many more she doesn't) and she loves how it looks (went for the lilac one). Set up was relatively simple, although you need to be quick with choosing your settings otherwise it times out and reverts back to the clock screen without saving your selection(s). Also, to connect to a PC you need the Dive Link USB Interface, not the Drak Interface as stated under Firmware Upgrade.

Brilliant first dive watch. Does everything you need it. Very easy to use and navigate. And once ordered, got to my house very quickly. Great Service!!

11 June 2019

I can’t fully review this yet as I have not used it diving, that said, it seems fairly simple to navigate which is what I wanted, nothing to complicated!! I’m diving in a couple of weeks so can up date then but first impressions

14 August 2019

I brought this computer as a back up when my Suunto broke on strong recommendations from friends. It's a great computer which is able to give you all the info you need during and after your dive. Dive & nitrox mode works well. Only thing is only having 2 buttons is a bit labourious at times. Would recommend.

30 September 2019

All good

8 October 2019

I like the look of this computer and it is also very easy to use - much more intuitive than some that claim to be. I noted that several others were using this model on my last dive.

21 November 2019

Once I read the instructions it was simple to use. :)

13 March 2020

Not being an over experienced Diver, I wanted an easy to use computer. Having used it, it is really easy to use and the display is great.

3 July 2020

Very simple to use have bought 3 of them now
