I don't think anybody has mentioned it explicitly, but a Garmin cannot read a Shearwater transmitter, nor vise versa.
So get two Garmins or two Shearwaters. Since she wants a Perdix that makes it two Shearwaters. You want a wristwatch, so that's a Teric or a Tern, and if it is a Tern then get the Tern TX just in case you want to read your gas pressure (and hers) too.
You'll spend upwards of $2000 to do all this, so go ahead and spend another $50 for a new SPG (they DO fail, you know) and replace all those old hoses you have.
 
Descent G1 base model is $550.

Tern TX is $775.

You'll already have a transmitter. So, for an extra $225, you could have a better dive computer, tank pressure on your wrist AND still use an SPG if you want.

But, it sounds like you want something that reminds you of your Casio, so that's that. Nothing wrong with it, either. The best reason for anybody having something is "because it is what I wanted".
Yeah that's mostly it, I like the way it looks and feels. I borrowed one for a day and I think I like the way it functions but even 30k pesos is still significant to me. I don't want to regret buying it. I'd like to hear of good reasons not to buy the Garmin Descent G1.

Do you also consider AI essential? Even for recreational diving? Would you expect any of the models you mentioned to last a decade? I maintain my gear meticulously and have a very high degree of confidence in my hoses, which aren't old, though my regulator is. I took it apart and replaced the diaphragm last year, I trust it.

I'd like for my wife and I to both have the same thing, but it's more important we each like what we have. I'd get my wife the two transmiters she asks for because she would use them even if one wasn't on my tank, so she says.

No, of course not, AI is not essential. But it is really nice to have because glancing at your wrist is faster and easier than finding your SPG and looking at it. I also think modern AI is at least -- if not more -- reliable than SPGs and hoses. Wireless AI also allows the remote checking of another diver's gas....which seems to be important in your situation.
Hoses fail. Do you carry any spares when you travel?
Diaphragms on regulators are pretty robust...why did you change yours? Did you also change the high-pressure seat, the inlet filter, and other soft parts? Do you keep an eye on your IP?
Confidence is good, but if it is due to lack of knowledge of what kinds of failures might occur it is not good, it's just scary.
 
lasting a decade? Pretty low bar...

In our collection of misc. pdc products (family):

Oceanic Veo 180Nx - over 10 years old and still running
Cochran EMC 20H - over 10 years old and still running
Shearwater Petrel1 - over 10 years old and still running

Perdix AI - nearing 10 years....

That sounds very good honestly. Glance at my watch and get all the info I need. I do want that, if it includes my gas and is MORE reliable than my SPG, that's very cool. I have had an SPG fail before. Remote checking of my gas isn't that important to me but after hundredds of dives with my wife where she is the only of us wearing a computer, she thinks it's improtant to her. It's important to me to humor her feelings.


Extra hoses are never far, even on remote islands or boats. I replaced all my hoses for miflex hoses a few years ago but my reg uses a half inch lp port for the primary second stage which at the time, I couldn't find a braided hose for. So I plugged that port and used a 3//8 inch miflex hose. However I did find one last year, so my hoses are in very good condition. I didn't replace the diaphragm in my 1st stage, I didn't even take it apart. I let a friend of mine do it and he used one of my service kits, of which I have a dozen, in case my regulator is discontinued by Mares, since it's over 20 years old.

The diaphragm that I replaced was in the 2nd stage, maybe it's not called a "diaphragm" but it is a diaphragm. I disassembled it just to see the inside, out of curiosity. I replaced it because it required a bit of a peel to remove from the metal and I didn't like the shape of it. The lever on the inside also appeared to be calcified so i consulted a friend of mine who owns a dive shop and is an expert in Mares regs. I also adjusted my octo with a screwdriver in a maneuver my wife didn't approve of.

I also don't let people touch my gear except for my wife, so my confidence is quite high in my gear.

Thanks for that. My wife wants a Perdix AI and I'm inclined to get it for her. What do you think of Garmin dive computers?

There are multiple reg-flags regarding equipment in your post, but I'll not comment further. Good luck.
 
Shearwater has just released the Tern, which is the recreational version of the Teric. It is available both without ($650) and with AI ($775). It's a great option if you're specifically looking for a dive computer. While the G1 is a "cheap" smartwatch with DC function. The Tern is definitely the superior DC and looks cooler :cool:
I'd like to know how you got to that conclusion. I feel like the polywhatever plastic is more durable than the metals. As for looks, I can admit I have terrible taste, I like the look of the G1 better than the Teric, despite being far cheaper. I haven't seen the Tern. I don't have a problem with saving money but I prefer to save money by having my stuff last longer rather than spending less on something that won't last.

By all means, criticize the Garmin, I'm not loyal to a brand. I'd like to know.

Well that's just hateful, I'm not sure how I offended you. Maybe you perceived overconfidence and disliked it?
