The Honest Truth



The Shearwater Perdix 2 is my dive com.  There’s not a feature on here that I don’t like, it’s literally perfect. They’ve thought of everything! I’ve even got a photo of Dive Dog Hal as my startup screen.

Its predecessor the Perdix AI is no more. This is the suped up version with titanium bezel and buttons, air integration as standard and all the the usual features we’ve come to love about Shearwaters.
