The Shearwater Teric Announced

[Jay]

Do we have any scientific papers about the benefits of having a real-time heart rate monitoring with deco adjustement procedures?

Cause I asked few days ago about Scubapro m2 and his heart rate monitoring and look like its not popular at all

I think the issue with SP's lack of popularity is not primarily driven by its HRM.

If there's one company that could successfully implement HRM in diving it's Shearwater!

Question re AMOLED display: I'm curious to know how this performs in bright sun (on land) compared to Perdix's LED LCD and Garmin's memory-in-pixel (MIP).

Edit: auto-brightness would be cool ... and even cooler the ability to tap/double-tap the screen to fully brighten it for x seconds.

Setting the aesthetics aside, one benefit that may not be clear is the fact within dive teams it's not uncommon to have identical gear. I know with my crew we have all chose different colored wire ties or other identifying marks to keep all of our gear straight. Colored bands could help prevent a computer mix up, especially helpful if doing repetitive or diving with AI yet reading data off your buddies tx.

For bands, this absolutely makes sense. For different-colored faces, I still think that's probably more for the owner's enjoyment rather than being particularly practical.

I bought white bungee and dyed it "Shearwater blue" with Rit dye for my Perdix, but I'm just that way.

Well everyone would agree.
And I would more than happy to use a Shearwater watch instead of a Polar and Forerunner multisport watch.

Can you explain why? In a dry/wet suit you could have a chest HRM. For my wetsuit I can get enough exposed skin on a wrist to make a watch based HRM work (for diving, swimming is different due to wrist impacts on water during strokes).

My opinion of course, but I'd guess the vast majority of divers using a Shearwater are doing long technical dives in caves or deep wrecks in cold water. Scubaboard members probably skew the numbers due to their popularity around here.

Nevertheless, that means the majority are diving dry making skin contact impossible. Even in a wetsuit you would be peeling back your suit and while I obviously haven't seen the Teric, most wear their computers on the top of their forearm, not their wrists.

Not to mention, diving, even oc tech diving is relatively safe if you plan your dive and follow your training. This makes the added cost and complexity (especially considering some kind of expensive wireless heart rate monitor) not worth it. Hell, these computers aren't cheap to begin with.

Finally, though you should have a level of gas contingency built into your dive plan, do you really want your computer changing the deco plan based on the fact you had a thrilling dive and now that cut your gas or even exceed the gas you have available, actually adding real heart stress?

Perhaps a better way to look at it is this. Do we really need every wiz bang feature? Or can we just enjoy the dive with a solid computer that does what we expect it to do.

It is possible to use the pressure sensor for an altimeter. This is a very common usage of pressure sensors, and the math is fairly straightforward. My issue with using barometric pressure for altitude is that frequent reference altitudes need be to supplied to account for variations to pressure due to weather. This tends to be more of a hassle than a benefit. Or, if only approximate altitude is needed, the variations weather can be ignored. I'll add it to the feature suggestion list, but cannot promise that it will be included.

One nice feature of measuring barometric pressure is recording the changes over time. This is a valuable weather forecasting tool and commonly used by boaters (or people who like to fall off boats). I would think a barometer would be a more useful function on a dive watch than an altimeter.

Can be interesting for rental dive computer or several computer for a familly divers. Now a simple name tag would also work. But customize is always cool.

You still have chest-belt and bluetooth
You can also have a wrist-belt (with sensor) thin patch and again bluetooth.

Not to mention, diving, even oc tech diving is relatively safe if you plan your dive and follow your training. This makes the added cost and complexity (especially considering some kind of expensive wireless heart rate monitor) not worth it.

I would also mention the same with AI. Might worth but clearly not needed if you goahead to safely plan your dive. The price between Perdix vs PerdixAI+transmitter are kinda different.

Now what would be wrong to have a Shearwater with Heart rate monitor as option just like the transmitter. You buy it if you want.

And I would clearly sell my Polar and Forerunner watch if such functionnalities are available on Shearwater.

I don't understand why skin contact is impossible with a dry suit (excuse my unfamiliarity) and why a chest / wrist based HRM transmitter couldn't be worn under an undergarment thereby providing skin contact.

re your other points, I don't envision it being implemented in a way that would cause that type of chaos / stress. As long as I know what the computer will do in certain situations then I'm happy. I'm not sure if I see it as a whizz-bang / must be everything issue, but more of a next logical step that is driven by divers diving (as opposed to divers cycling, running etc). Any secondary benefit would be cool, not not required.

I don't see the comparison to a heart rate monitor that doesn't provide anything relevant to a dive opposed to an AI transmitter that provides breathing gas tank pressure and real time sac rates.

I mean ****, if I am surprised by a group of Manta Rays that popped up unexpectedly, you bet my heart rate is going to increase, I don't need to check my dive computer to confirm that.

Frankly I think Shearwater made a pretty sweet Technical diving instrument. Not good enough?
