When I initially took the guages out of the box I thought the dials where a little small but once in the water no problems. I dive in fresh water lakes and they tend to be darker and have very loose bottoms. The Mares Mission 3 gauges where very easy to read even in these conditions and being compact they tend to not get in the way. Also this is a great features when packing them in your gear bag. Great job Mares. I would recommend these guages any day of the week.

Rating: great console for the beginner
Reviewer: Jack F.
I purchased this for my son as part of his dive kit. He has used it on a few dives now and likes the ease of reading the dials, the glow in the dark features, and the hook points for his retractable cables. Great product for those that are starting to put together their dive kit on a budget.

Questions and Answers for Mares Mission 3 Gauge:

  • Alvin:

    Are the depth gauges in feet? and the air gauge in pounds x square inch (PSI) ??

    Bill  (Certified Scuba Instructor at

    This console is in imperial measurement which is in PSI and feet.

  • Jerry:

    Can diver replace the batteries?

    Bob  (Certified Scuba Instructor at

    Being an analog console, there are no batteries to be changed. So, no you cannot replace the batteries.


    hi there i just wanted to ask is this item available or i have to wait for the stock as always.

Boot: shock-resistant elastomer.
Hose: 7/16” UNF length 90 cm.
Dimensions: 250 x 72 x 44 mm.
Weight: 460 g


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 • wrench; if you have a dynamometric wrench
available, apply a closing force of 8 N/m. The pressure gauge is ready for use.


Before using, the user must carefully ensure that the pressure gauge is compatible with the
maximum working nominal pressure values of the regulators on which the device will be
mounted. The nominal working pressure for the pressure gauge is shown on the back of
the case.

After assembling the SCUBA set, slowly open the tank control valve to avoid the “water hammer”
effect resulting from the high pressure entering the hose. Never look directly at the instrument
dial when opening the tank valve.

In models designed for use with Nitrox, always open the valve(s) on the tank(s) very slowly to
reduce the risk of the mixture combusting. Once the tank valve is open and the system is
pressurized, reclose the valve and make sure there are no leaks, checking that the pressure
indicated by the needle on the pressure gauge is stable and does not drop. If a drop in
pressure is detected, do not dive and double check the entire system.

During the dive, remember to check the residual air pressure frequently.
The pressure gauge features a reserve supply indicator (area between 50 and 0 bar marked
in red), designed to tell the diver when the tanks are nearly empty. If the gauge pointer
reaches the low-air sector during the dive, it is necessary to start the ascent.
The pressure gauge is equipped with a hose long enough to avoid hindering the diver during
use. It is in any case recommended to secure the instrument using the special fasteners
provided on the harness or BC. Protect the instrument from knocks. The pressure gauge must only be used with
CE-marked SCUBA components.
