I need to identify the ones for the Petrel1, Perdix, and Peregrine....

I measured the O-ring that came with my Perdix protector (purchased this year from Paragon, thank you!) and I think it's 2x52mm.

I'm including a picture of mine, as the styles differ somewhat. I've had it installed for around 5 dives or so over a couple of months, so not sure if the o-ring stretched out a bit in that time. Also I was a theater major, not an engineering major so this measurement should be taken with more than a grain of salt.

How do these install?

They set over the front, and a rubber o-ring secures them across the back side.

Does this add-on scratch the dive computer? Also, since it's aluminum, what precautions do you recommend after diving?

As an FYI the covers will also fit the New Perdix 2 and Petrel 3

Any benefit to these over silicone on the perdix 2?

If carefully placed on the Perdix, no. Over time. perhaps there'll be some slight scuffing at contact points but none to make it unattractive to a knowledgeable and experienced diver. If you're jarring the AMX hard, then you'd be doing worse damage without it.

More integral fit. Part of the DC. "Hood" provides just a bit of shade for improved reading at the surface. Makes a difference (IMO).
