First session with the Mach 1; it´s really amazing; a lot more stablish than my old Reflex 6.

I was sailing yesterday in Arinaga with Twan Verseput, same sail, (Starboard 90 L for him) and he show me de better heading and some others setting details. Thank you big boy !!

I´m very happy with the results, but I had even better recording with my GW60 : Peak 35,71 and 10 sec 34, 53, but a friend of mine deleted "by mistake", he said.
