Thanks to Galicia Technical Diving for the help, support and patience.
The old ‘creme’ colored USB-to-Serial cable APDiving used to provide with their rebreathers doesn’t work out of the box with Windows Vista, 7 or 10.
This is a driver issue, Windows will install a driver that simply doesn’t work with the cable.
In the beginning and ending you can see my Instructor/Buddy; Pieter De Vos/FOX. Visibility wasn’t that bad (we’ve had worse) but I’ve seen other movies when the visibility was much better in Thorn. The water was pretty cold and so we limited our time in the water.
