Compared to other computer watches, the iDive Free does not simply calculate surface recovery time needed between two dives, just taking into consideration the first dive, but can be set to consider the kind of dive just performed (for example a dive of descent and ascent, without stop at the bottom, as in freediving, or a descent, stop at the bottom, and ascent, just as in spearfishing, when nitrogen is accumulated in greater quantities).
Value 1 refers to base recovery time to avoid Taravana, with a value that is double diving time. Particularli interesting on the iDive Free are the functions which permit to regulate in 10 different levels the algorithm that calculates surface the recovery time. Adjustable depth alarms are available, as today in almost all quality computer watches. The wide quadrant is made of scratch resistant sapphire. The Ratio watch has quite big case and quadrant, where the case is fully machined in 316 stainless steel, which gives the watch a solid and rather technological lokk, even though for some it might feel a little heavy (128 grams), while others, indeed, like the more “important” feel on the wrist. The iDive Free is complete with all the most commont functions in computer watches for feediving and spearfishing. The new model of computer watch iDive Free from Ratio is distributed worldwide by Salvimar.īorn mainly for freediving and spearfishing, the new 100% Italian computer watch is also complete with ARA functions, such as decompresion tables.
