You can not disagree with his fundimental premise that relying on a single piece of technology is foolish, which is why we are all taught to wear a watch with some sort of timer (a rotatable ring) as well as carrying tables. For any agency to abandon this would be utter madness. As we start using computers a lot of people abandon tables, I am no angel in this as my old padi tables are floating around in the red sea somewhere as they blew off the boat about 5 years ago.
However. the piece of kit he is really attacking, very cleverly I admit, is the VR3. It has to be said, I am the eternal skeptic with this bit of kit, but I am going to get myself one. It offers the advantage of real time up date of your dive profile, uses a modified buhlman table and gives deco profiles very similar to the tables I run off prior to each dive. It allows for the fact that although I have planned for a 65M dive my actual depth was probably 57M, this gives a reasonable saving in deco when bottom times are 40 mins. With a deco commitment of well over an hour, 5 mins can seem like an eternity, if it is possible to save this then I for one will take it thank you very much. Having said this, only a raving maniac would rely exclusivly on a single piece of kit, which is why all the people I know who dive a VR3 also carry a dive timer of some sort as well as tables and bail out profiles.
My attitude is simple, technology can be fab, use it wisely and it will give massive advantages. Try to be clever and it will hurt you.
