Hi I bought the Mares Wide because my aging eyes could no longer read the smaller digits on my Suunto Stinger underwater.
I have been using it for over three years now and found no problems with reading all the vital information when using it. I have my prescription lenses in my mask but hate bifocals so I have distance only prescription so to read without use of bifocals is a godsend. On the surface my spectacles are varifocal but these lenses are not as yet available for diving masks.
The Mares Memo Wide comes into use automatically at around 1.2 metres so no need to remember to switch it on. It also switches off automatically when left unused for a period this time varies depending on which function is being used at the time. It will let you set it for salt or fresh water and for nitrox as well as air. I mainly use air so mine is set for nitrox at 21% Note: the Mares Nimo can display in feet and degrees farhenhiet as well as Metres and degrees Celcius.
The rapid ascent warning on this computer is a bit twitchy so if you have a cuff dump on your left sleeve then I recommend you wear the computer on your right arm otherwise you'll get a rapid ascent warning every time you raise your arm to dump a bit of air. the beep can be switched off or on so if you're not too good on your bouyancy control I recommend you have it switched on at all times until the nagging of your more experienced buddies make you take a few lessons in bouyancy control! :-))
The strap length of the Mares Nimo is very generous I have no difficulty in fastening it on my suit even though I have a 3mm neoprene suit and, as I dive in winter, a very thick undersuit too and I always have enough strap and more for the job. (Hint: Although I've never had a problem with my buckles there is a first time for everything so wear a wrist lanyard as well.)
The info display is large and easy to read in most light conditions but it can also be backlit by pressing and holding the top button for two seconds. This gently illuminates the screen with a green glow for around four seconds and makes the figures stand out well.
The Mares Nimo wide screen also has a deep stop warning that lets you know how long decompression time you need and at what depth. It has arrows that keep you within these safe boundaries. The deco time itself is displayed in very large digits so you are never in doubt as to how much no deco time you have left.
The battery has a good life (I've changed mine once in three years and I dive weekly) and is user changeable too so no sending it off for weeks on end and paying a ridiculous price for the privilege as was the case with my last computer. Whatever computer you buy always ask this question as sales folk have a tendency to forget the drawbacks when advising customers.
The memory is good and lets you scroll through the dive minute by minute and for an extra cost you can buy a CD and lead so you can download the relevant info onto your computer. The cost of this is around £80 which I think is a bit steep but hey if you want it why not?
I didn't buy a plastic screen shield for mine and now wish I had as I managed to catch it on a wreck and do it some mischief thus reducing its value if I ever sold it on. Oh well you live and learn.
On balance this computer is very good values
