Suunto EON Steel, EON Core and D5 dive computers with Suunto FusedTM RGBM 2 and Suunto FusedTM RGBM algorithms provide 5 personal setting options (+2, +1, 0, -1, -2).
These options refer to decompression models, which can be conservative (+2 and +1) or aggressive (-2, -1, 0). Generally speaking, conservative means safer. In practice it means that a dive at a given depth is shorter due to the decompression obligation (the no decompression time is short).
|Personal adjustment value||Condition||Description|
|-2 (P-2)||Ideal conditions, excellent physical fitness, highly experienced with a lot of dives in the near past||Progressively less conservative|
|-1 (P-1)||Ideal conditions, good physical fitness, well experienced with a lot of dives in the near past|
|0 (P0)||Ideal conditions||Default|
|+1 (P1)||Some risk factors or conditions exist||Progressively more conservative|
|+2 (P2)||Several risk factors or conditions exist|
Conservative also means that the time the diver needs to spend on decompression is longer. For recreational divers, a conservative model means less time in the water in order to avoid decompression requirements. For technical divers, however, conservative means more time in the water because of the longer decompression requirements imposed during ascent.
Aggressive models, on the other hand, increase the potential health risks of a dive. For recreational divers, an aggressive model allows more time at depth, but may significantly increase the risk of DCS. The Suunto Fused™ RGBM and FusedTM RGBM 2 adapt its predictions of both the effect of microbubble build up and adverse dive behaviour in the current series of dives. The default setting for the Suunto Fused™ RGBM and FusedTM RGBM 2 is to use a compromise (0 setting) between conservative and aggressive. With the personal setting, you can select gradually more conservative or more aggressive calculations.
The personal setting reflects the fact that personal health and behaviour have an impact on your DCS susceptibility. Therefore, we recommend consulting your physician regarding your fitness before diving. Any of the following can potentially increase your risk for DCS:
