Im currently in the market for a computer. i have narrowed my options to the Suunto D4i and the Oceanic Geo 2.0. Theres not a huge amount to choose between them in terms of spec, but id like some advice from other divers before i part with my hard earned cash. Im after something that is watch sized that can be used in and out of the water. trying not to break the bank but need something that is going to last a while. Any help would be awesome, thanks.
