Modern digital dive computers date
to the early 80s, though analog devices simulating tissue gas uptake and
elimination through porous membranes date back to the 70s. Analog devices were limited to nonstop diving and had a short shelf life.
Digital dive computers
proved highly successful and very useful right from the start, progressing from
just table emulators to full up algorithmic staging devices across mixed gas,
open circuit (OC), re breather (RB), nonstop, decompression, deep, and shallow
diving. Dive computers are moderately expensive items these days, and high end
units range beyond $1500. Basically, a decompression computer is a
microprocessor consisting of a power source, pressure transducer, analog to
digital signal converter, internal clock, chip with RAM (random access memory)
and ROM (read only memory), and pixel display screen.
