Diveavenue's expert opinion

The Perdix 3 is the logical evolution of an essential benchmark. What I particularly like is the switch to an AMOLED screen: the contrast is sharp, even in murky water or during night dives. The addition of the titanium bezel provides real peace of mind when it comes to the knocks and bumps that are part and parcel of life on a boat. Being able to change the AA battery yourself on the other side of the world remains a major advantage for travellers who refuse to rely on a specific charger.

Frequently Asked Questions (FAQ)

Can it be used with transmitters from other brands ? The computer is optimised to work with Shearwater Swift transmitters, but it uses a standard protocol compatible with most air-management transmitters operating on the 38 kHz frequency.

What is the main difference compared to the Perdix 2 ? The Perdix3 features a brighter, more energy-efficient AMOLED display, as well as a slightly slimmer profile reinforced by its titanium frame.

Is the screen glass protected ? Yes, the device comes with a screen protector already fitted at the factory to minimise the risk of scratches during handling or contact with other objects.
