The CYPRES wasn’t the first AAD ever created but with its  visionary cutter system, superior engineering and electronics it  revolutionized the way the skydiving sport viewed AADs forever.

There is a reason that all modern AADs look like a CYPRES.

A proven maintenance plan, a driven dedication for excellence and  frequent innovations defining today’s skydiving industry standards have  made CYPRES the most popular AAD worldwide. Accept no substitutes!
Only CYPRES owns the necessary unique technology to give you the utmost safety your AAD can provide.

• Unique cutter design – for a clean and reliable cut of the loop.
• Unique handling and haptic – very easy to use and proven to avoid unwanted input.
• Unique ground calibration – for maximum accuration. The AAD which compensates air pressure changes due to weather.
• Unique technical service – a worldwide maintenance  system on its own that has yet to be matched. Comprehensive treatment  and all applicable updates – flat rate with an attractive pricing.  Recommended only every 5 and 10 years.

To make installation of the CYPRES AAD easy, literally all usual  sport skydiving parachute containers are factory prepared for the CYPRES  set-up. Verify with your container manufacturer / rigger that your  system is CYPRES ready.

The m² multi is an electronic automatic activation device, operating on the  principle of pressure reading. The primary means of detecting the  altitude and fall rate is a pressure sensor. The altitude is calculated  based on the difference between the two atmospheric pressures. The  pressure at current altitude and pressure on landing location “GROUND  ZERO”. The pressure on the landing location is measured and set after  switching on the device during calibration. This pressure is  automatically adjusted by a change in barometric pressure during the day  without the need for user intervention. The m² multi checks the ambient  barometric pressure every 32 seconds and it determines whether the  aircraft has taken off. If yes, it begins to monitor the skydiver’s  altitude and fall rate. The pressure sensor measures the atmospheric  pressure 8 x per second in free fall.

The information collected is evaluated by means of a microprocessor  and ingenious software and it is converted to a real fall rate and  altitude. Thanks to this, the m² multi-device is capable of meeting the  preset criteria of fall rate in combination with altitude above the  landing location, cut the reserve parachute closing loop by means of the  cutter and thus initiate the deployment sequence.

The device is activated only in the case the preset criteria are met; the criteria differ depending on the set profiles – STUDENT (Stu), INTERMEDIATE (Int), PROFESSIONAL (Pro), CANOPY PILOTING (Cpi) and TANDEM (Tan)

• When switched on, the Vigil® performs a complete self test to check  all internal parameters and calibrates itself at the atmospheric  pressure of the DZ altitude.
• When the “”  logo appears, the Vigil® is ready to go with you on the plane.  The Vigil® is now ready for use and is in a “stand-by” status  (recalibrating itself every 32 seconds).
• During take off, Vigil will go to an “active” status and starts measuring the air pressure 8 times per second.

• Once the door opens and you leave the plane, the Vigil® will  calculate the time left over before reaching the activation altitude  (for example: 1100 ft in PRO mode), by continuously measuring your  falling speed and your altitude. The Vigil® takes in consideration the  speed variation during the free fall and recalculates every 1/8 of a  second the time left to reach the activation altitude. When you reach  the activation altitude (time = 0) and if you are still falling at a  speed above the preset value (for example:35m/sec in PRO mode),  the Vigil® will  instantaneously activate the cutter to allow your  reserve parachute to deploy. This patented method ensures a very  accurate activation altitude (+/- 60 feet).
• Vigil® works by permanent recalculation of the time left before activation (see patent).
  • EU Patent N° EP 1084950B1
  • US Patent N° US 6,378,808B1

• The Vigil II has been designed to resist a water immersion of 0,5 meter for maximum 30 minutes (IP 67).
• Vigil 2+ and Vigil Cuatro, are waterproof (IP 68) and can withstand water immersion of max. 1,8 meters for a maximum of 24 hours.
• The Vigil® doesn’t need filter replacement. It has a built-in  stainless steel air filter which does need to be replaced after contact  with water (see chapter 6 of User’s Manual).
