Just received, can wait to dive with it in the next weeks.
Which is better Tern TX or the Peregrine TX?

Trying to see in the manual but can the display be set up for non-AI use or will it always have a blank or dashed space for tank pressure?
All I ever wanted for Christmas was my two front teeth since they got knocked out and now all I want is a Peregrine with a compass. The rest of it I have no use for.

What about screen readability? Peregrine's larger lcd display vs. Tern's amoled (supposedly more vibrant)?
I use reading glasses and even then some computers with monochrome lcd and small numbers I find hard to read.

I do not have the Terric so I can’t compare, but I never had an issue with the Peregrine and now the Peregrine TX. Display is clear and in brightness auto mode perfectly readable. You can either set it to high if really you have difficulties.
Only downside with the Peregrine TX so far is the compass. It’s pretty unusable, moving heretically and by 20 degres off. Try to calibrate multiple time today without success. Not sure if it’s my unit or a more general issue with digital compass (my Apple Watch Ultra seems just fine).

I am a new diver and have old man eyes. I cannot read without my glasses. I went to look at a Peregrine as my geek treat before my OW certification. Despite a lot of research, I didn’t know the Tern was released a few weeks earlier I REALLY wanted the possibility of AI, but wasn’t willing to look at a Perdix or Teric.
I wanted the Tern due to the AI but knew it was worthless if I couldn’t read the display underwater. The much brighter and sharper OLED made me choose the Tern TX. I can read it very well underwater! I have not tried to figure out the compass yet because I suck at navigation and want to learn on a plain old compass first. I did not have a transmitter because I wanted to learn diving with an SPG. That went well, and I am now looking forward to using my new Tern transmitter.
Had the Peregrine TX been out when I made my purchase, I am confident I would have stayed with the Tern TX because of the very bright, razor sharp display. Either is a great choice!
Tern Tx vs Peregrine.
So, was traveling on a tiring business trip and as consolation got myself a Peregrine Tx. This turned out expensive, had to appease jealous wife with a Tern Tx.
So now got both, and after first weekend of diving can compare them.
Screen-wise, I personally prefer the Peregrine as it has more real estate and for a geek like me, I used bottom line to show SurfGR, GF99 etc. The little I tried with the Tern, it seems that customization is limited to one field only (we set the display to "Big", don't know if there is more space with smaller fonts). Unlike the display on her Suunto D6, I could see the information on her Tern (e.g. safety stop counters etc.) from a distance without even needing to communicate about that.
Both displays are bright enough to see in bright sunlight- it was a blazing 47 Celsius weekend, had plenty of sun.
Wife loved the outer compass ring, said it is really useful while DPVing around it enhances situational awareness. I set the Peregrine also to show compass on mini display2, but it is too small and although can be used, is better showing the whole compass ring during navigation with DPV.
In night dive this was a game changer for me. I really hated having to press a button for 3 seconds to get a dim light, or getting blasted when illuminating with a torch to read the display.
AI: both worked flawlessly. I tried to start dive with the computer turned off and see how it works with the transmitter. The computer woke up at about ~1m depth showing a "Critical air" red warning since it was not detecting the transmitter at first, and it took some ~15 seconds until it caught up the transmission and began to monitor the tank pressure.
Battery: We dove about 6 hours. I couldn't find where the Peregrine shows battery percentages, but from the looks of the icon it was ~95% full (back home it took some 5 minutes to complete charging).
The Tern battery was spent from 100% to 66% in these 6 hours, so it seems the charge can hold max ~17-18 hours on Max brightness. I set the Peregrine on "auto" brightness. I suspect the battery on the Peregrine has a larger capacity and can hold up more working time.
Only criticism that I have is that although they may be robust, they don't feel so much like it. Maybe because we are used to stainless steel casing and Saphire glass computers, both Tern and Peregrine feel a little plasticky, and I wouldn't think of using them without a screen protector. We are used to throw the computers "as is" in the bag with cameras, regulators and all dive gear all happily together, these babies we feel cannot share the same space with regular gear- they will get scratched to death- need to get used to place them always in their protective cases... The Peregrine's screen seems a little better protected (the bezel/frame is thicker and higher)
Wish they had Saphire glass (Shearwater: hint, hint, hint)
Overall, we like the computers. I don't like watch straps and prefer big screen and have fun looking at all the various info displays, so a Bungeed Peregrine is the choice for me, whereas my wife always preferes the watch form factor (and she is content only with the main display info) is happy with the Tern.
I did not mention, but we both use reading lenses and both computers were also ok to read without them.
TL;DR: It boils down to form factor preference and battery size, functionalities are the same.

It is possible to set declination by +/-10 degrees.
I checked both Tern and Tx against a military compass and they were accurate about ~10 degrees, which is pretty decent for a scuba compass IMHO. Unlike a mil compass with sights and milliradian resolution, for most divers who don't cover long ranges it is more than adequate.
