Giuliano De Fari - IANTD Trimix Instructor 4722
A diving deco planner software highly recommended for planning any technical dive since it’s easy to manage, very accurate and as far as I am concerned, a valid back up to my Shearwater Petrel. One of the most interesting feature is the possibility to operate on the GF and choose the desired safety margin relatively to M-values line. Personally my compromising choice is for a GF 30/80.
