XL4W/DB4+ S2 set

Lightweight, compact, for cold water.

XL4+ is based on the XL4 platform, introduced in 2017.The 1st stage DB4+ has 2 HP outputs, allowing you to connect a traditional manometer and dive computer sensor at the same time.The 2nd stage XL4W in the new white design is very lightweight and compact.The XL4+ is cold water ready (EN250A) and is the perfect choice for the traveling diver, regardless of the location chosen.

The XL4+ is also an excellent stage regulator for technical divers. The shape and light weight of the Stage 2 significantly reduce jaw fatigue during challenging, long-duration dives. The rugged and compact 1st stage's durability has proven itself, among other things, during demanding transports of large amounts of equipment.

This regulator is not offered in the S3 set. The Octopus can be ordered separately. We recommend combining with the XL4 octopus, but all Apeks octopuses are compatible with this controller.

The XL4W/DB4+ regulator has been tested and certified in accordance with EN250A (50 m, 2 °C, simultaneous breathing from main and backup second stage).
