Oceanic B.U.D. (backup device) backup computer.
Actual unit depicted here:

This Oceanic B.U.D. dual-algorithm computer supports Nitrox up to 50% for single-gas dives.
I was using it as a backup to my Oceanic VT4.1 to ensure I have information available even if the main computer fails.
It is usable as a basic depth-gauge and bottom timer as it will not completely lock out even if it thinks deco has been omitted. Run time and depth info remains available.
Oceanic's original product description follows:
Set it and forget it. The B.U.D. is a long overdue idea and a great way to ensure that you never have to miss a dive. Clip it off or stow it in a pocket and forget about it. B.U.D. is a universal backup dive computer that uses Dual Algorithm technology allowing you to adjust your dive computer's settings to closely match just about any other dive computer on the market making it the perfect backup device. You should never have to use it, but if you do need it, your B.U.D. will be there to save your next dive. This new Dive Computer is a must for every diver to carry because no matter what computers you are using, you will be able to set your B.U.D. to closely match any computers profile using the Oceanic Patented DUAL ALGORITHM.
