Why are the Shearwaters held in such HIGH REGARD?

[Derelict]

After 125 dives using my trusty Oceanic Geo 2, I've upgraded to a Shearwater Perdix (recently into some decompression diving) and after 2 basic shore dives I'm already in love with it. I almost don't even need to focus on the computer, I can have a quick glance through my peripheral vision and see everything I need to see about my dive on a single screen. Cant wait to do some proper technical diving using this!

I think that the planners do not always match the computers as there is no specification for GF.

In another thread it became apparent that various members of this board believed that the GF Lo did not matter for a no stop dive. Part of the reason was that trying it they found that the value they set did not make a difference. Some examples were planners, some dive computers.

So the question arises, where in the dive does the change over between GF lo and GF hi happen? Starting at the bottom? Starting at the first stop? And if at the first stop what if there are no stops? Is the GF lo the limit at surfacing (the surface being the first stop) or is it GF hi (the surface being the last stop)?

The question is really: At which depth (or ambient pressure) to apply GFlow. Reading the original Baker document carefully, you will see that i applies at the depth where you first touch the ceiling (i.e. your first stop). In Subsurface, that ceiling is computed (assuming GFlow everywhere) and then linearly interpolated to GFhigh at the surface (I wrote that code).

Customer service is absolutely the best

That was the major factor in my decision to purchase shearwater computers. Most of the other features can be found in other brands. Shearwater seems to stand out by having a good product and good customer service.

The fact that it will take any battery you can stuff into the compartment is pretty novel, too. I dig it.
