First the price of 209.95 was over 300.00 until I called in and diver-supply price matched and then went on-line and changed the price. I couldnt believe that a company would drop $100 dollars from a product price that quick. The product arrived ahead of time that is was to be here. It took me about an hour to 2 hours to go through the book and understand how the dive computer worked. Very easy to learn, but I would turn the "beep" off while you are learning the computer. I drove my wife nuts. I will be doing 5 dives this weekend and will let you know how it goes. I have had nothing but a positive experience with this company.
