  1. great piece of it review by Robert on 13/06/2013

    Amazing price and equally amazing service.
    I thought it would be really complicated to use but its very straight forward.
    I used youtube for a quick way of learning how to use it.
    cant wait to get it in the water

  2. Very happy review by Simon on 19/03/2013

    Happy with this computer. I wear it as a back up when solo diving and it seems a lot less conservative than the gekko. Easy to wear around the house too.... like a chunky 1970s wristwatch in size. Menu easy to use. One frustration was accidentaly going diving in freedive mode and them being locked out of changing the mode for over 24 hours. Good for the price. Kicking myself for buying it JUST before the special offer of the free transmitter!!
