Ratio Dive Computers Announces New iX3M 2!! Our Best Dive Computer yet!

but doesn't register start air pressure & end air pressure

It certainly does when you download the log into Subsurface.

I contacted Ratio, but no answer... .

They respond within 48 business hours usually or less. What email did you use for them?

I bought the Pro version after reading a bit on internet (and this forum).
All in all it's a very decent computer - very intuitive too.
I bought the wireless transmitter to be able to read out the air (up to 300 bar), but that's not really working :-(

Downside :
- transmitter supports 300 bar but only allows reading out 254 bar (and lower). What the hell is this. My old Suunto transmitter could read out 350 bar without problems. A bit misleading that they don't mention that when you want to buy it (you can find it in the manual though)
- the dive computer shows you the air (254 bar & below), gives an estimation of remaining dive time... but doesn't register start air pressure & end air pressure (well, that wouldn't matter too much if you start with 300 bar) ...
A bit disappointed that those 2 things are not working as they should (compared with my Suunto experiences). I hope they fix that in a later release...

I contacted Ratio, but no answer... .

I've mentioned the 254 bar thing previously:

Ratio iX3M2 transmitter on HP cylinders

I've recently hooked my Ratio iX3M2 transmitter onto my twin 7L (300bar) tanks, and have noticed that the pressure reading shows a maximum of 254bar. It'll read 254 bar until the pressure drops below that, and then it decreases in line with my SPG. I've submitted a support ticket, but got a...

Yes, disappointing. Wouldn't have been much harder to use a pressure sensor rated to 400 bar and give the full range.

It does capture the start and end pressure, along with the pressure at 1 minute intervals throughout the dive. You should be able to see that if you download into Subsurface. But you are correct if you mean that you can't see the start and end pressure in the on-device logbook.

Hello Boltsnap,
I mailed 'info@ratio-computers.com' 7 days ago (that's the support address via their website).

Hello Stiebs,
Thanks for the return - I did learn something thanks to you & Boltsnap (that it has the data, just not showing it in the on-device log).
I checked the Subsurface tool, works as a charm there (< 254 bar).
I hope that they take this as a feature for a future version (would be nice to see that in the on-device log ...).

For those interested I got an answer from Ratio today on the limits of the transmitter & not visible in on-device log:

1. The transmitter does support a maximum pressure of 300 BAR; however, the current maximum readable value is 252 BAR. We are actively working on and testing a version of the transmitter that will read up to 300 BAR, with a maximum pressure tolerance of 450 BAR.
2. The dive computer does record air consumption data, but for space and screen clarity reasons, it is not displayed graphically on the computer's dive log. However, I will forward your request to our R&D team to evaluate the possibility of adding this feature in a future update.

Excellent!!

So was thinking of getting another transmitter as my current one is a royal unreliable pain in the arse and noted that Ratio has really upped their prices in everything. Anyone else notice that. Upgrade codes for the various computers have gone up, transmitter prices gone up as well as the computers them selves. Will be skipping on any more transmitters from Ratio too high a cost considering the grief I have had so far with my one

How did you manage to connect DC to Subsurface via Bluetooth?
I connect to the DC with BT and I have status CONN under PC mode for BT, but then when in Subsurface I have nothing under connection no matther which computer I select. I tried it with 3 different Android smarphones.

I was also looking for a solution to this; I ended up emailing Ratio directly, and they were kind enough to answer with a detailed how-to video I am linking below (hopefully without violating any rule...).

TL;DR: You need to enable (manually, each time Subsurface is run) the option called "Show all Bluetooth devices" in the advanced settings of Subsurface. At least, in my personal case on iOS (iPhone/iPad), this was the only piece missing! I see this is also mentioned in this other thread, but I somehow missed it...

Hope this helps! Sorry for the necro posting.

On that note you should probably also avoid buying a new car or bicycle. Or groceries for that matter.

The Ratio transmitter is €400
A quick Google tells me a Shearwater transmitter is US$400, a Garmin one US$500
Suunto runs cheaper at around US$320

* Disclaimer: This was a cursory search, not an exhaustive one.

You should also note that the pressure sensor device inside the transmitter is about 1/3 of the price by itself, before the manufactures even add design, additional circuitry, tooling, and margin.

None of my cars, cycles or groceries are as unreliable as the ratio transmitter. Ill pay over the odds for reliability. My point was in the last year alone there has been at least a 30%+ increase in their prices for no apparent reason
