Instructions for use



Improper use of dive instruments may result in serious injury or death.Read and understand these instructions thoroughly

 before you dive .


*The pressure gauge with H.P is made to be used with compressed air only.

*Link the hose at the jacket to avoid pressure gauge traverse.

*maximum pressure = 5,000psi(350bar)
    Temperature= 0 to 100℉(-5° to 45℃)
    Thread size=7/16” ╳ 20- UNF

*Connect the hose to the high connection of the regulator ,after preventively having anointed the O-rings with silicon


*The pressure gauge with H.P.hose satisfies the requisite of the European Normative specifications CE EN250.


Standard of precision by CE EN 250 NORM

± 5bar a 50bar ( ± 70psi a 700psi)
±10bar a 100bar ( ±140psi a 1,400psi)
±10bar a 200bar ( ±140psi a 2,800psi)
±10bar a 300bar ( ±140psi a 4,200psi)


*The wear and tear subjects components of the pressure gauge like H.P. hose , pivot pin , O-Rings , must be periodically

 verified and replaced.

*With the purpose to limit the deterioration of the O-Rings we recommend the periodical use of compatible lubricant.

*After the use , rinse the complete pressure gauge with fresh water and keep the instrument dry.


*Always keep the pressure gauge dial away from your face when turning on your tank valve.

*Dont use solutions to clean the glass (the raw material could lose his unbreakable characteristic).

*Never obstruct the one-way vent valve located on the back side of the gauge.

*Use two 15mm wrench to close , not forcing the link excessively.


*The black needle with red tip indicates current depth and as depth increases it pushes the thinner needle.

*To reset the max depth thinner needle for a new dive,turn the slotted knob located in the center of the gauge face counter

clockwise until it just makes contact with the black needle with the red tip.

*steel(copper-berylium for military) membrane system of reading that elevated sensibility and precision.
*Dial with parabolic scale to improve the precision of reading on the various depths.
*Dont expose the tool to sources of heat.
*The employment over the maximum value of suitable scale on the dial can damages the tool in irremediable way.
*The Depth gauge satisfies the requiste of the European Normative specifications CE EN 250,13319.

(+1.0m.-1.5m) a 70meter ( +3.28 ft.-4.92 ft ) a 230 ft


*Rinse the depth gauge with fresh water after dive and not employ solutions to clean the glass(the material could lose the 

characteristics of impermeability or transparency if put in contact with not compatible substances).

*Do not obstruct the depth sensor opening located on the back side of the gauge.

*Never over come the maximum attainable depth from the tool(equivalent to the end scale printed on the dial of the tool)


*The compass is mainly used to follow a predetermined direction. The red line on the covert glass,points out the direction 

that you need to take.

*Always avoid the direct expose of the tool to the sun or to sources of heat and rinse afterdive with fresh water.

*The contained liquid in the compass can develop bubbles of air if exposed to sources of excessive heat.These bubbles 

dont invalidated the good working of the compass and they have the tendency to disappear when temperature come back to 

normal condition.
