INTRODUCTION
The ALPHA-PRO X-DIVERS is an hardwired, full-duplex
underwater communication system for conversations between
the surface and one or two divers.
It is an upgraded version of the ALPHA-PRO standard with
powered volume for both diver and surface. Moreover the volume of
the underwater unit can be adjusted from the surface unit to allow
the divers to have the best comfort during the dive.

Professional surface/diver cable (50meters -165 ft long) (if sold
separately code OR033134)
6 pin cable with yellow rope exterior. The cable’s diameter is 10mm
with a resistance of more than 4000 Newton.
The cable includes waterproof rubber 6 pin connector at the diver
side and DIN connector on the surface side.
The Professional cable is also available at any length on request.
A carry-bag is available with the cable and sold separately as an
accessory.
4000 N is the tear up strength, audio signal may be lost
earlier!
It is fundamental to pay attention that the cable does not get stuck on the boat or on
the seafloor. It is also very important to keep the cable slightly buoyant, by attaching
a small buoy or floating device to the cable a few feet away from the underwater unit.
It is a good idea to connect the cable with a hook or retractor to the BC jacket,
avoiding any traction between the surface and the underwater unit. During the dive
the surface operator must slowly feed the cable out to the underwater diver as
needed, while keeping voice contact. It is not advised to simply throw the cable into
the water. The same procedure should be used when the dive is completed and the
cable has to be brought on board.
