A must for advanced divers
For anybody who is doing more than staying well within the no deco limits this is as must. Coupled with a dive computer using zh-l16c with gradient factors it allows you to quantify the impact of a dive exposure on your body and find the right GF combination for you, optimize your deco time and determine whether you are using the best gas mixes to suit your individual physiology. The purchase of the O’Dive sensor is well worth it.
