-Nylon-glass filled housing
-Shatterproof lens
-Scales up to 60m
-Max depth gauge
2. ACCURACY MEASUREMENTS
3. MAX DEPTH GAUGE
The black needle (with red tip) indicates current depth. As depth increases, it pushes the thinner needle.
As depth decreases, the black needle (with red tip) continues to indicate current depth while the thinner needle
remains at the maximum depth reading achieved. To reset the max depth needle for a new dive, turn the
slotted knob located in the center of the gauge face counter clockwise until it makes contact with the
black needle (with red tip).

3. USE
The pressure gauge is a safety device used to monitor residual air pressure in your SCUBA cylinder (tank) for open-circuit
SCUBA diving up to a maximum depth of 100m / 328ft. The pressure gauge is intended to prevent a failure in the supply of the
breathing gaseous mixture in the scuba cylinder that divers breathe throughout a dive. The pressure range of 50 bar and below
is marked in red to alarm divers of an approaching failure in the supply of breathable gaseous mixture. NEVER exceed 100m
and check the pressure gauge frequently to ensure there is a sufficient supply of breathing gas in your tank cylinder.
4. ASSEMBLY
Ensure that the pressure gauge is compatible with the maximum working pressure of your 1st stage regulator before assembly.
The maximum working pressure for the pressure gauge is 300 bar. Locate the high pressure ports marked ’HP’ on the 1st stage
regulator (please refer to your regulator user manual) and remove the HP port plug from the port you select. Place a small
amount of halocarbon lubricant (Christo-lube MCG 111) on the HP hose end threads and O-ring. Fully screw the hose into the HP
port of the 1st stage regulator and carefully torque to 4 to 4.5 Newton meters (35 to 40 inch pounds).
5. ANNUAL INSPECTION
Return the pressure gauge to an authorized InnovaSub technician for annual inspection to ensure safe operation and
maintenance. An authorized InnovaSub technician will inspect the pressure gauge, depth gauge, and compass, verify dial accu-
racies, and replace the pressure gauge swivel (air spool).
6. PRE-DIVE PREPARATION
Test if the instrument is properly connected to the 1st stage regulator by slowly turning the screw knob until the tank is
completely open while avoiding to look directly at the instrument dial. After pressurizing the system, listen for any leaking and
check the pressure gauge needle to determine if there is a drop in pressure. If so, double check the entire system and avoid
diving until the problem is resolved. If the instrument shows visible signs of disrepair like cracking, please immediately return
the instrument to an authorized InnovaSub technician to determine whether the assembly can be fixed or requires replacement.
7. POST-DIVE MAINTENANCE
Soak the instrument in fresh, warm water for one hour and flush the instrument boot with running water. Towel dry before
storing in a cool, dry place out of direct sunlight. KEEP OUT of extreme heat environments exceeding 45°C (100°F) to avoid
harming the instrument. When transporting, please store in a soft padded bag avoiding to knock or bump the instrument.
8. CE CERTIFICATION
The pressure gauge (pressure indicator) is a Category III device as defined under European Regulation 2016/425 and complies
with the specifications set out in the harmonized European Standard EN250. The pressure gauge has been tested by Dive Lab
Inc. at 1415 Moyland Rd., Panama City Beach, FL 32407, USA to guarantee a minimum level of safety at a maximum depth of
100m in conformity with European Regulation 2016/425. EU type examination was performed by SGS Fimko Oy Notified Body
number: 0598 Takomotie 8, FI-00380 Helsinki, Finland. Declarations of conformity may be found at https://www.innovasub.com/
support/. These certifications are for metric only.
