Title: Not All are Created Equal: Operational Variability in 49 Models of Diving Computer
Author: Azzopardi, E; Sayer, MDJ
Abstract: Diving computers marketed in Europe must comply with European Standard EN 13319:2000. Some EU occupational divers employ diving computers to calculate and manage decompression schedules; they have also been used as depth and temperature measurement tools. This on-going study is evaluating and validating the performance of diving computers in relation to realistic operational requirements. Depth measurement and recording from 49 models of diving computer were analysed at pressures of 203 to 608 kPa; temperature measurement was assessed over ranges relevant for polar, temperate and tropical environments. Decompression isopleths for single square-wave profiles were constructed and compared with tables; occurring unit faults were recorded. Depth conversions, temperature measurements and decompression schedules varied markedly between different models of diving computer; units may not conform fully to EN 13319:2000. A total of 49 “faults” of varying seriousness were recorded over a total of 2009 operational hours. Occupational divers need to risk-manage the use of some computers for decompression management and be aware of the potential for battery or unit failure. The accuracy levels of depth and temperature recordings made by diving computers may not be acceptable for some scientific and forensic studies.
