Suunto Vyper computer.
	Suunto's Viper retains all the top features of the Cobra but utilises the traditional SPG air contents gauge. It retains up to the minute reduced bubble gradient decompression model technology and full nitrox capability. The Suunto SK-7 compass can be added to make a tri-gauge combo (add $155). The Vyper is also available as a wrist mount unit for $1180.
