Integrated Data and Illumination System

product code: OR025010 (SDVL mounted on a PREDATOR M/L black)
product code: OR025008 (SDVL mounted on a SPACE M/L black)
product code: OR025004 (SDVL mounted on Neptune SPACE series mask - mask sold separately)

When checking important data while diving (depth and air pressure), a diver usually has to look at their wrist or console display instruments to do so. When a diver's hands are occupied or when visibility is low, keeping track of his or her gauges may be difficult.

With the SDVL, the depth and pressure data are comfortably displayed on the right and left sides of the Neptune Space visor. These two displays are accompanied with visor lights installed in the visor top. The depth and pressure displays are activated the moment the diver enters the water. The visor light (made of 6 in-line LEDs) is easily activated by a switch on the right side of the mask and incorporated in the surface air valve set.

The SDVL is composed of:

  • A main unit with a removable and rechargeable battery, fitted with a tank belt handle, low pressure and high pressure sensors, and wet switch contacts.
  • The battery may be easily unscrewed, recharged and replaced. It is protected by black anodized anticorodal housing, with an overpressure valve to prevent explosions in the case of a battery malfunction. There are two o-rings on the battery body that ensure an even seal in case of an incidental partial unscrewing.
  • A 110/220 volt battery charger is supplied with the SDVL.
  • A High Pressure hose to be connected to your first stage.
  • A wire connecting the main back unit to the mask, which is provided with two waterproof multi pin connectors for quick connection and removal.
  • A double PTT button unit to control the on/off of the visor light, the brightness of the visor light, and the on/off of the depth and pressure display LEDs (if not exceeding the preset safety limits shown later).
  • Two LED displays for the tank pressure status and the diver depth. The LEDs work by a reference bar and 10 LEDs showing the present data. It is an analogical/comparative display that gives the diver an immediatereminder of tank consumption as well as where the diver is in correlation to a 50 meter/164 feet of water depth.


The SDVL turns on automatically as the diver enters the water and the unit gets wet. All LEDs remain turned on for a few seconds to show the unit is working properly.

During diving the two LED bars turn on, depending on tank pressure and depth (see schemes below). LED brightness can be adjusted by means of the control button, adapting to environmental conditions (day or night diving, cave diving, etc). To achieve this, press the SDVL control button until the desired intensity is reached.

The LED bars can be switched off and on by pushing the control button quickly. For safety reasons, the two bars will turn on automatically if the tank pressure gets below 50 bar or if you dive deeper than 40 meters. The LEDs have 3 different colors to report ergonomic information to the diver.

> 131

The air pressure display has two sets of LEDs. One is the reference line, where various green or red LEDs show the tank pressure level (see schemes below). No digital information is given. Regarding the reference line, the diver will have an idea of how much air remains in their tank. Flashing red pressure LEDs advise the diver that their air reserve is running dangerously low.


At the beginning of the dive only the reference bar turns on to indicate the unit is working and will display a depth of 50 meters / 164 feet. Once the diver descends past 5 meters / 15 feet the LEDs will light up accordingly, giving a reading of corresponding depth. At 40 meters / 130 feet the LED turns red. At 50 meters / 164 feet the LED red light flashes. It is important to remember the SDVL is a support system and is NOT an alternative to the conventional pressure and depth gauges, or computers. The SDVL provides, at a glance, information allowing the diver to quickly evaluate the relative conditions (air supply and depth) of their dive.
