Perfect item


Great delivery time


Awesome Dive Computer


I lost my D6i a few weeks ago. Realized I was not responsible enough to have a wrist computer. Now that I have a hose integrated computer I will not have to worry about losing it again. The great thing about changing over is that the cobra's functions are exactly the same as the D6i.This allowed me the freedom of not having to be educated on a new computer.Being that I am a cold water diver I loved how the buttons were large.I wear 5 mm gloves and it was always hard to press buttons underwater on the D6i.


Nice Compu


Good purchase, good price, everything works well…
