MacDive has an overlay for NDT which is imported from my peregrine. I saw in a MacDive release note where they added importing NDT from Shearwater dive computers. Neither MacDive nor the peregrine operating instructions says what NDT is. What is NDT?

I am looking for a Petrel 3 controller for Dive Rite Optima (it can be from either a back mount or a chest mount unit given that the head is the same). Let me know if you have a good unit you are looking to get rid of.

This is all theoretical, I'm not even a technical diver, but I am a nerd and have been reading the manual of the Shearwater peregrine and if I'm understanding things correctly, then I don't understand why technical divers still use safety stops when these values are now visible on modern dive...

I always dive with 2 computers (NERD 2 and Perdix 2 when in CC or Teric and Perdix 2 when in OC) and I end up with duplicate dives in my Shearwater Cloud. This requires manually deleting one dive for each couple from both the Cloud and the device (if you don't do both they keep getting uploaded...

Hey fellow sea dogs , I'm looking for a Shearwater Peregrine, or possibly the bronze journeys edition of Teric. Locate in Vancouver, BC, Canada, but would cover insured shipping.

I can figure this out by looking at the dive tables, but I'm thinking the Perdix 2 should display this info while in surface mode. I know it tracks surface interval but I don't see any mention of displaying minimum surface interval in the manual. Like if I dive to 60ft for 40 minutes, will the...

I am a new diver and trying to decide between the two computers. My fear is that if I buy the Peregrine I will end up incurring the more costs in a few years if I do decide to upgrade to a more feature rich computer. My concern with the Perdix 2 is the opposite. That I won’t use the features and...

Fellow divers and freedivers, I recently got a Peregrine (wow, I absolutely love what Surface GF is teaching me about diving - thank you for the recommendations!). Unfortunately, for the first time I encountered a minor issue with it yesterday. I was free diving in the cenotes in Yucatan (in...
