Bio-gauge COMBO Cobra Nrx
Cobra boot equipped with a compass
The triple gauge that a compass is added to the popular Cobra boot. It places all three gauges in the optimal layout for clear visibility and ease of use.
Luminous scale plate glows for hours
The scale plates of the compass and the residual pressure gauge are painted with Japanese-made special phosphorescent agent, which will glow stably for hours once exposed to the light. It is ideal for night diving.
Unique residual pressure warning function with brightness perception system
Unique residual pressure warning function with our patented brightness perception system(B.R.System) will inform the reach of lower limit of residual pressure by blinking an ultra-high brightness orange LED. By the adoption of the B.R.System, it minimize the power consumption to the limit while the tank is not being connected. It will automatically start up to full operation mode once the tank is connected and being in use.
