Help me find a new Wrist Mount Computer

People have spoken favorably of the H3 (SubGravity and SeaBear are the same thing). The xDeep/Genz Black has a couple long threads here that are worth checking out.

I have an xDeep BlackBT and it's alright, but certainly nowhere near as nice as any of my Shearwaters.

Screen size is too small. It has the same screen size as the H3 (1.7"). The T1 just has a larger body and the wheel interface. The benefit of the H3 is the smaller form factor, just a little bigger than watch size. The T1 really doesn't get you anything other than a different style of interface, which, despite having yet to play with it, I can't really see that it would be that much better than a 2-button interface. I can't imagine that it would be impressive enough to get a Shearwater user to switch, and will probably appeal to new buyers, or technophiles. I have been known to be wrong before.



The Petrel has a 2.4" screen. Doesn't seem like much, but in fact is much larger. Of course the whole computer is much larger as well.

Johnny, I have had the chance to compare all 3 side by side. As for H3 vs T1, you do actually get something different with the T-1. According to Subgravity, the larger form factor allows for a battery that is twice the size as the H3, for twice the life. For me that is a major improvement. Also, the wheel interface is, also to me, light years ahead of the two-button interface, which seems clunky by comparison. So, for my $$$, the T1 is a better option between the two. I have no desire or intention to use my dive computer as a watch, so I favor one optimized for dive functionality as opposed to small size or good looks.

On the screen size, I do tend to agree that size matters. The Petrel seemed more readable. But, even between the T1 and the Petrel, the overall size difference is also substantial. The T1 "big number" screen is very readable and bright, very close to the Petrel's readability, but the Petrel does display more information.

This is just to give my impressions. I would look at them both. In my case, I am one of those divers where AI could tip the balance away from the Petrel, but SeaBear has suddenly gone mum on AI.
