Announcing the SubGravity H3 - Powered by SeaBear

[FindingMenno]

I just ordered an H3 (in Europe). I wanted a computer suitable for recreational diving (to replace my dying 10 yr old Vyper), and with the possibility for Tec diving in the future.
After looking at many computers, in the end it was a match between the OSTC Sport (2/3 of the price but only Nitrox) and H3. The smaller form factor of the H3, the non-user replaceable parts/battery (less chance of flooding), the future option of AI (and GPS?), Apnea mode and the free upgrade to Trimix this month tipped it over in favor of the H3.
Of course I couldn't neglect the awesome reputation of Shearwater, but the size factor just didn't work for me as an active recreational dive instructor.

However, as an active dive instructor doing approx 500 dives a year, I do also wonder about any battery replacement program if the battery wears out in 3 years or so? In this case the non-user replaceable battery can also be a negative... Then again, I wasn't looking forward to changing a battery over every week or so on an OSTC/Petrel...

For those interested, I made a little sheet and with some of the features of my favorites.

The SubGravity H3 powered by SEABEAR is designed and built in Austria by SEABEAR Diving Technology utilizing some of the highest grade components in the industry. The battery is certainly replaceable. It is not user replaceable, but would need to be returned to SubGravity for service. The H3 has a 2 year warranty, including the battery. We anticipate that the lithium battery will last for several years. If and when it does fail, it can easily be replaced by the service center.

Hope that helps answer your questions about the battery.

Kind regards,
Randy

It doesn't really answer the question that I asked: How much does/will a battery replacement cost, if the H3 is out of warranty?

Also, since I'm asking questions, once the H3 is out of warranty, if I send it in for a battery replacement, what is the subsequent warranty? How long is the new battery covered? And what and for how long is covered if, say, the computer floods and dies 5 dives after I got the battery replaced?

Hi Stuart,

The warranty on the actual H3 is two years from date of purchase. Installing a new battery in the H3 after the warranty has expired does not extend the warranty on the computer itself. I don't have any pricing on battery replacement due to the fact that we have not had to replace any as of yet. We'll work out pricing on battery replacement when and if we start to experience any failures down the road. Sorry, wish I could be more specific about pricing on future problems that might arise, but we just haven't had those types of issues to deal with as of yet and if they were to happen during the first two years of ownership, it would of course be replaced free of charge.

Thanks, Randy. I understand about being so new there is nothing in place yet for out-of-warranty repairs.

What about my question about the cost of the unlock of multi-gas and Trimix? How much are those things? if I buy one, it will be for use in my upcoming AN+DP class, which would mean I would need multi-gas and, depending on pricing, possibly want to just go ahead and get Trimix at the same time, for down the road.

The SubGravity H3 powered by SEABEAR is fully unlocked. There are no PIN upgrades and as such comes fully compatible for Nitrox, Trimix and CCR.

Randy (MixAddict), any update on when the "science unlock" will be available. So far this is the only feature I feel the H3 is lacking.

Hi Tom,

I don't have any info on the Science unlock right now for you, but will definitely let you know when we have more info!

Does the seabear H3 or T1 compensate fresh and salt water? I could not find that in the manual.

That's the "science unlock" I'm waiting to hear about. It's mentioned in the online manual for the H3 under Settings, Settings sub menu, H2O Density.
