On the left, we have my Cochran Commander. It's over 20 years old and is a bit basic by today's standards, but it's never let me down in those 791 dives and it does two nitrox mixes so worked fine as my backup last week.
On the right, we have my computer by divecomputer.eu, or the PPOS as we've nicknamed it. My first one had to be sent back for a pressure sensore failure after 6 months. The repaired computer flooded the first time I used it and this replacement has been stuck in bootloader mode for over 6 weeks. divecomputer.eu are to date ignoring my support call raised on 30th August 2019.
Why PPOS? Well divecomputer.eu are based in Poland, so PPOS stands for Polish Piece Of Shit.
