Oceanic Geo Air vs Shearwater Peregrine - Please help!

[rmorgan]

Neither the Geo Air nor the Peregrine have a compass.

Peregrine TX does

Garmin does have a G3, but it will not work on a scuba dive.

Are you referring to the SP G3 or the Garmin G1?
I have a Garmin MK2s, and find that it’s compass works just fine for me.

It's the G1. Thanks for catching that.

Looks as though it's the aftermarket band. It's only slightly magnetic but it's enough to throw off the compass.

Apologies to Garmin for questioning their supremacy in all thing navigational lol.

yea, thanks for reading back a couple of posts

The newer version of the Peregrine has a compass. The originals didn't. I have one of the earlier ones. The screen is awesome. The induction charging was the killer app for me, having had computers lost to flooding, this was huge.

The Peregrine TX has a compass and supports air integration, $700. The Peregrine has neither of these features, $550.

This thread prompted me to try the the digital compass on the G3 for the first time. It's got a lot of lag and/or wild inaccuracy. Using it for real navigation would be a nightmare. It confirms my strong preference for a good analog compass.

I'll take full credit for this!

Thank for all your replies, the vast majority of you seem to advise that Shearwater is the only way to go. I do like the look of the Peregrine, and the reviews I've seen seem to suggest that it's held in very high regard, not to mention the innovation and standards that SW has introduced to dive computers in general.

Now, I just need to get that Shearwater logo tattooed across my chest and we'll be all official...

Makes sense. I use a similar aftermarket band on my MK2s, but always revert back to the OEM band for a dive. The MK2s has the Quick Fit lugs, so I can swap them in seconds. IIRC, the G1 Solar also comes with Quick Fit, but the G1 doesn’t. Not sure what’s needed to make it compatible.

Yes, the G1 works with the Quick Fit bands - that's what the metal one is.

Yeah, I hear it's great when your Birdic dies every 3 months and needs to be warranty-replaced. When you buy something that ain't broken in the first place, OTOH, who cares.

I don't know anyone who bought a Perdix that has had to send it for servicing. I have read a couple of posts.
I've had mine since 2018 and have 949 dives on it. Never had an issue with it.

You claim is they die every 3 months is just nonsense.

I said "birdic" not "birdix". There is a difference.

Anyway, I just the Shearwater fanbois who answer "Geo vs. Peregrine" with "Tern TX!" and "great support when your Teric goes titsup!"

Peregrine. Even without AI/compass it’s still a good, solid computer. I have the TX version and I love it. The display though not an OLED like on the Perdix/Petrel is worth it, and it can do “light” tech - no trimix/CCR support but you can stage up to 100% O2(with some setup of course) for deco diving.

The 4 button watch style DC like the Oceanic (but excluding the Shearwater versions), have the worst user interface of any piece of tech I have ever used. There are 4 buttons, there is no reason for short press, long press, combo press requirements. I had a geo for years, and my work used to have a fleet of the sherwood version of the same computer. I had to figure out how to change nitrox settings every time.

We replaced the fleet of Sherwoods (actually two fleets since we had to have 2x as many as we needed because half of them were in for service at any given time) with Perdixes, and the students figure out how to change settings with zero instruction faster than I could remember out how to do it on the old ones. We have about 50 shearwaters and have had to send maybe 3 or 4 back for service. We have had buttons not responding and pressure transducers going bad, everything has been replaced or repaired with no issues. But keep in mind, our heavy use computers probably get 7-15 dives per week, and the students abuse the crap out of them. I have no idea how they manage to scratch up the screen protectors as quickly as they do. We'll charge the computers a couple times per semester.

For digital compasses, of the ones I have used, they are okay for knowing which direction is north, or which direction to go back to shore, assuming you remember to calibrate it every day/dive. Anything more complicated than that and I have found them almost useless. If someone put a rotating bezel on a dive computer, I might feel differently, but there is more to a compass than a north seeking needle.
