D5 or Teric - convince me

Excerpt, from another Post.
He advice to me........Shearwater Perdix.
It is a "Top Shelf." Decompression, Mixed Gas Computer. He specifically said NOT to buy the Air Integrated. (It could propose an unwanted failure, different scenarios were discussed.)

Ummm... yeah.... Having the AI model (but not using the AI) could result in an unwanted failure because of the unused AI.... And you could also get hit by a meteorite during your dive....

If you don't want AI, I agree that buying a Perdix is a good choice - but I would strongly recommend anyone to look for a used Perdix for a good price, rather than buying a new one. Shearwater is the only dive computer company I know of that has a 2 year warranty and it's transferable. A used non-AI Perdix is usually not TOO hard to find from someone who wants to sell it upgrade to a Perdix AI or Teric.

For AI, I would only (personally) invest in the transmitter that is used by many, including Shearwater. There is a reason why so many brands use that same transmitter. It has been around for years and proven that it just works. Not that they never, ever break. But, they are pretty darn reliable (if you do the manufacturer specified maintenance - i.e. replace the battery on schedule, with a new, properly-lubed O-ring).

My reply was in regard to Shearwaters Customer Service.
I have to be more careful, how I post. People read "Only." what they want.
Technically, this was my fault. My apologies.
Cheers.

Had to re-read the post after seeing 120 with 32%

Glad it was all done in the planning mode!

Great catch! Indeed.

You compared the Teric on Medium conservatism to a D4i and sold the Teric because it gave you less NDL?? You know that Medium is SUPPOSED to give you less NDL that, for example, Conservatism set to Low, right?

Yes, of course, I realize that. My point is that one would think that a medium conservatism the Teric would roughly match the D4i. But that's not the case at all.

Your results are impossible, as it's a well known fact that all Suunto computers are irrationally conservative and couldn't possibly give a longer NDL time than a Shearwater under any circumstances, despite hard evidence to the contrary here.

Uh, can't tell if you're joking. Leaving aside my admittedly non-scientific findings, did you watch the video?

I was being facetious

This is a screenshot from the review I referenced in my original post. You will see that the D5 indicates 24 minutes of NDL while the Teric shows only 17. I suppose it's possible he had the Teric set very conservatively but he doesn't say so as far as I can recall (it's a lengthy video).

Looking at these I see 10 minutes of gas time remaining and 17 minutes of NDL, I also know that the Teric will increase the NDL as you come up. If the real concern is extended NDL just dive the old tables but you’ll need more gas.

My apologies.

No worries. I dive a suunto and have been very happy with it. I know that shearwater makes a great computer, but there is a level of cultism with some that's laughable.
