ENOS locating system

When a diver drifts out of sight.

ENOS is a GPS based locating system for dive boats. The diver carries a transmitter. Once surfaced, the receiver on board shows distance and heading.

  1. The ETX transmitter is rated to 100 m (according to NRC).
  2. The position is sent by radio, without a SIM card and without a subscription (according to NRC).
  3. Range of up to 10 km, depending on antenna height (according to NRC).

Intended for dive centres, liveaboards and organisations that run boats.

ENOS helps with finding divers at the surface and does not replace dive planning.

SailAir compact air system

Air when you need it.

SailAir is a compact, refillable air system for boats. A 1 litre cylinder with a regulator helps with work under water, such as checking the hull or clearing something from the propeller.

  1. The 1 litre cylinder is small enough for a locker or a bag.
  2. Refill with a hand pump or compressor. According to NRC, the air system itself needs no electronics and no batteries.
  3. According to NRC, one fill lasts about 15 to 20 minutes, depending on depth and exertion.

Intended for maintenance work and shallow, calm use. Not a replacement for a full scuba set.
