Suunto Vyper Dive Computer FREE DELIVERY The Vyper features full decompression capabilities & combines several technological innovations in one product. Vyper offers everything a diver could possibly need for diving with standard Air or nitrox mixes. It can also be used as a depth gauge & timer with profile memory, making it ideal for professional & technical diving applications. Vyper features a unique advisory system that guides the user. The SMART & scroll push buttons give easy access to the multiple functions of the computer, both in & out of the water. Based on experience acquired over many years from the study of saturation technology, Suunto has carefully fine tuned the mathematical model behind its computers. The Suunto Reduced Gradient Bubble Model (RGBM) used in the Vyper is a modern algorithm for tracking both dissolved & free gas in blood & tissues of divers performing a wide variety of manoeuvers.
