hi, the manual for this instrument (on mares website) reads: *** warning the pressure gauge is designed for use with only one gas mixture. at the time of purchase, the purchaser must choose the mix to be used: breathable air or oxygenenriched breathable air (nitrox). preed mixture - air: the pressure gauge is designed for use with air. the air used in the tank must comply with the en 12021 european standard. for safety reasons, mixtures other than that indicated may not be used. preed mixture - nitrox: the pressure gauge is designed for use exclusively with nitrox, maximum 50% oxygen. for safety reasons, the use of air (en 12021) is strictly forbidden, as is the use of mixtures other than nitrox or oxygen, which could contaminate the equipment. warning it is strictly forbidden to switch from using air to nitrox and vice versa *** if i dive using air and nitrox up to 40%, can i use the same console for both?
Yes. Mares is using a very strict "CYA" policy in terms of liability. The manufacture's policy is the word when it comes right down to it, and regardless of our personal opinion and knowledge of it, when it boils right down to it, if the manufacturer says their gear can't be used in a certain way, then it's typically best to not use their equipment that way.

The submersible pressure gauge is a safety device for monitoring residual air pressure
in the tank, designed to be used as part of a SCUBA set (open-circuit, self-contained
underwater breathing apparatus). The pressure gauge must be assembled on
the regulator first stage by means of the high pressure hose connected to the gauge.
The pressure gauge can be used at temperatures below 10°C.
1) Locate the high pressure ports on the regulator first stage (refer to the instruction
manual of the regulator; the high pressure ports on the first stage may be marked
with the letters “HP” or with the maximum pressure rating) and, following the
instructions, remove the plug from the chosen port.
2 ) Remove the thread protection cap before connecting the hose to the regulator first
3) Screw the hose fully into the high pressure port of the regulator first stage. Tighten
firmly but carefully, using a 14-mm hex
After use, it is recommended that you rinse the instrument in fresh water while it is still
assembled on the regulator, to prevent water from penetrating inside the hose.
Allow to dry in air, and then put the instrument away, taking care to replace the special thread
protection cap on the hose. The instrument should be stored in a dry place,
protected from heat sources and direct light, without bending the hose too tightly (minimum
bend radius 20 cm).
• Avoid exposing the instrument to direct sunlight or sources of heat.
• Treat the gauge like a precision instrument and avoid bumps or knocks.
• Rinse in fresh water after every dive. It is recommended that the 108 O-ring Vitron
gasket, located on the threads of hose coupling which connects to the pressure reducer, be
