But to what end? Why is a teric a better computer than a Perdix, and especially a better backup computer? Will you take two chargers on holiday?
Reasons I like the Teric better:
- form factor. You may or may not know that I owned a Petrel 2 for a time, then got a Seabear H3. I dived them both long enough to determine that I really did not like the brick form factor. I sold the Petrel at a non-trivial loss.
When the Perdix AI came out, I bought one because I was willing to live with the form factor in order to have the AI. Now, I don't have to live with that brick any more, in order to have the Shearwater features and quality - and AI.
- screen is better/brighter (on the Teric, vs the Perdix).
- the perimeter compass on the Teric is awesome and the Perdix does not have it.
- the 4 buttons make navigation easier. It's not a huge deal, but it is easier. Many's the time I have scrolled right past the option I wanted on my Perdix and had to go all the way back around again.
- The Teric battery definitely lasts long enough to not need to charge them both on the same day - unless I royally screw up, of course. So, only need to take one charger. The same charger, in fact, that I would take anyway, to charge my phone.
- The Teric supports a display mode that has 4 rows of data on the screen, instead of just 3, if you care to use it (and your eyes are not too old to read it). I normally wear reading glasses, but I have my Teric configured for Standard (i.e. 4 rows, vs Big, which is 3 rows) and I can read it without any gauge reader lenses. And the 3rd/4th row (depending on whether you use Big or Standard view), can still be setup for up to 3 pieces of data, which the user can choose.
- I have had issues with the buttons on my Perdix being activated inadvertently. I.e. by my dryglove rings or something else. I personally know 2 people who have told me that they had a gas switch performed on their Petrel/Perdix without them knowing it, because of accidental button presses. IIRC, I posted this before and at least one other SB member posted that they had had the same thing happen to them.
I am much more confident in the Teric to not have inadvertent button presses, versus the Perdix.
- The Teric has a new feature called "Tag Log" where you can add text tags to your log during a dive. E.g. "waypoint", or "Danger". There's a menu of choices. When you download and view your logged dive's profile, you can see at what point in the dive you were and what tag you logged. The Perdix does not have this feature. It's a minor thing, but does seem like it could be somewhat useful on occasion.
- I would not normally wear the Teric as a watch. But, on a dive trip, I *would* leave my smartwatch at home and wear the Teric as a watch during the trip - any time that I want to have a wristwatch on, anyway - which is admittedly not very often.
- I work for a shop that is a Shearwater dealer. I don't know for sure yet, but I think I will be able to buy a Teric and sell my Perdix AI such that my net out-of-pocket is very low, if anything.
- To me, especially for technical diving, a backup computer is like a backup reg. I want the same thing for my backup as for my primary. If I end up NEEDING it, why would I want something that is any less "good" than my primary? If I'm on a dive trip and my primary computer dies, I'd rather fall back to using another Teric for the rest of the trip than fall back on using a Perdix. For all the reasons already given.
Forums are to discuss things - but those things should not be questioning how someone else chooses to spend THEIR MONEY (and in a snarky way)!
I don't mind if somebody asks why I choose to spend my money a certain way. Snark is not really appreciated, but I'll do unto others as I'd like them to do unto me. In this case meaning give the benefit of the doubt and take the comments and questions at face value.
I'd bet we'll see a Perdix 2 with an AMOLED screen, rechargeable battery and other Teric features, However, but given the enormous success and resultant backorder situation in manufacturing, I don't think we'll see it that soon?
Shearwater changed from the AMOLED screen on the Predator to the LCD screen on the Petrel because they could not get the AMOLED screen anymore (in that size/resolution). At least, that is my understanding. I suspect that that supply issue may still be the same. So, I do not personally expect to see a replacement for the Perdix that goes back to AMOLED.
I also don't expect to see a Perdix replacement using a rechargeable battery. If the computer is the size of a Perdix, may as well preserve the option to use an AA - and the ability for the user to use rechargeable AAs if they want to.
It dosen't have location marking with GPS however.
True, but as the Teric is already supported by Subsurface and Subsurface-mobile, one can achieve the same end by simply using Subsurface-mobile, taking your smartphone on the boat with you, and running the Subsurface Location service on your phone while you're at sea. When you download the log from the Teric, Subsurface can pull your GPS coordinates from the location service data, to match up date/times with your dive log and yield a Subsurface dive log that has your GPS data. No need to pay extra to have GPS hardware incorporated into the dive computer itself.
