The OSTC 3 looks hardcore and really well build.

Nice writeup Andy

Thanks! This review has helped me decide on which computer I will get next.

You have an incorrect depth rating for the Petrel, it should be 300m (for “crush depth”) compared to 260m for the Perdix.

Helpfully you've tried to block copy/paste on your site for reasons I can't fathom.

Was aware of the crush depth, but the depth sensor accuracy depth is what I listed. That's direct from Shearwater's site/manuals.

I guess it's lucky for me that I just placed a Shearwater Perdix on lay-away at my LDS.

To quote Shearwater directly:

The guaranteed depth accuracy range is to 130 msw / 425 fsw [...] It is designed to withstand pressures up to 30 Bar (290 msw / 950 fsw) [...] The Perdix case is rated to a crushing pressure of 260 msw / 850 fsw [...] The Petrel is rated to a crushing pressure of 300 msw / 985 fsw
​

The numbers you list for one of the two is wrong. Also the Perdix and Petrel 2 manuals list individually a depth range for the sensor and a crush depth for the actual housing.

Got it.... and thanks.... that needed an edit. I've listed both depths now.

Again... you've got to admire Shearwater for their transparency. Wonder what the 'depth ratings' for other computers actually represent.. crush depth or sensor accuracy. In my mind... for technical diving... sensor accuracy is what counts.

Shearwater does a lot of things right. Even their bugfix releases notes are clear about not only what was fixed but why it was wrong.
