We entrust one of the most important data regarding our safety, if not the most important, that of the air pressure in the bottle, to an extremely simple and inaccurate instrument, the analog manometer, a copper spiral through the which an orifice detects the pressure and offers the reading in a dial by moving the needle. With DIGI 2 Cressi proposes a high-precision instrument that also provides other data of constant interest to the diver. All this with a very contained size and cost. Construction: Minimized size: 60 x 50 mm box Anti-impact ABS casing with thermoplastic rubber sheath that integrates a fixing ring 45 x 27 mm phosphorescent rectangular display with anti-impact and anti-scratch bumpon protector Large digits (10 x 5 mm main data) with segments separated by distribution lines Magnet post-production battery saving system. The smart box (patented) can be used to keep the DIGI 2 in dormant power saving mode and perform tasks such as switching of measurement units Battery replacement by the user without the need for tools. After changing the battery, DIGI 2 performs a pressurization self-test (patented) to ensure that it has been carried out correctly. Battery cover specifically designed to avoid incidents with two retaining clips and to offer easily replaceable parts (O-ring) Completely modular construction that allows, when the time comes, to be repaired Automatic ignition when pressure is detected Supplied data: Tank pressure with 3 digits (accuracy of 0.1 bar) between 0 and 340 bar Current depth with 1 decimal Maximum depth of the current dive Maximum depth of the previous dive (when tank pressure is detected) Immersion time Datum temperature: Remaining time to reach reserve pressure (50 bar). Updated every 1 second according to the respiratory rhythm of the moment Great autonomy: up to 700 dives in a year. Six colors available: black, white, blue, red, fuchsia, gray.
