Hi @Jafo19D

It appears that your Mares Nemo Wide is entirely adequate for your diving. You can turn the deep stop off, I would.

One of the dive computers I currently use is an air integrated Oceanic VT3 that I purchased in 2010. It runs the DSAT decompression algorithm. It has 1999 dives and 2098 hours on it and it works perfectly. I could easily execute my diving, no stop and light deco, using this computer alone. I have dived a number of backup/second computers. In 2016 I bought a Dive Rite Nitek Q because I wanted to learn and become familiar with the Buhlmann ZH-L16C deco algorithm with gradient factors. In 2019, I bought a Shearwater Teric. I have about 700 dives on the Teric. Today, I dive the VT3 and the Teric, both run off the same Pelagic Pressure Systems/Oceanic MH8A transmitter.

My Teric has features that I find extremely valuable for my relatively simple diving. SurfGF allows me to know what my surfacing GF will be. I used to somewhat arbitrarily pad my safety stop or my last deco stop, something like an adaptive safety stop. Now, I simply follow my SurfGF and execute my final ascent for my chosen surfacing GF. I do a lot of drift diving in SE Florida, the floating north compass pointer is generally all I need for guidance.

As you consider a Shearwater computer here are a few points. All the SW computers have SurfGF. The Peregrine does not have a compass, the Peregrine TX does, no north pointer. If you would also consider a watch factor computer, you can look at the Tern and Tern TX. The Tern does not have a compass, the Tern TX does, with north pointer. If you want AI, you can always buy the computer alone and add the transmitter later, but a package purchase currently saves you $100. You could also use any of the PPS MH8A transmitters that can often be purchased used.

Best of luck in your computer decision
 
Mares compared to Shearwater is like comparing a bicycle to the space shuttle.
 
Not that I would consider one, but Mares has several good looking computers running Buhlmann,
I am sure if divers used this as a recreational computer to depths 100 fsw and shallower with no deco it would be safe and adequate considering Shearwaters are around $1K.

I have no experience with Mares computers. The Genius, Sirius, and Quad CI are trimix technical diving computers. The Genius and Sirius are in the same cost range as the Perdix 2 and Teric. The Quad Ci is a bit less expensive.

I haven't used a Mares computer, and don't intend to; but there's one singular advantage that I know of for one:
You can sync logs to the SSI app (if that's something you care for)

I also never used a shearwater for OC so, not too much to say in regards to this comparison. 🤷
 
Shearwater Peregrine is a great unit. I have the non AI version. You will love the display. Also dont have to worry about fiddling with O-rings and clunky cable connections. Because it charges from just setting it on the wireless charging base(although I wish it was magnetic).
 
Deep stops are added by some proprietary algorithms such as the various flavors of RGBM but have more or less gone out of fashion. The Shearwater has a much nicer display, runs standard Buhlmann GF, and won't lock you out if you make it sad. It will turn on automatically should you forget to do so. Making the switch should be a no-brainer.
I don’t think that what OP mentioned is a deep stop in the sense (a deep deco stop, which have been indeed gone out of fashion after their potential has been refuted)
This sounds more like what Scubapro calls a PDIS (profile dependent intermediate stops); yes a proprietary modified Bühlmann; but its effect is limited to NDL diving; when in Deco it doesn’t include it (but the lack of gf customization and the choices of depth increments are wild so still annoying)
I have been using that (PDIS) for a while; and it’s a bit similar to the idea of „riding gf99/surfgf“

OTOH, zHL-16C does permit deepstops if you have your gf lo pretty low (10-30) 🤷🏽‍♀️
But it’s still the better choice I agree, vanilla and non proprietary

We're talking about the Mares Nemo Wide, it has deep stops, nothing like Scubapro PDIS
