Customer Reviews
"The differences were evident, first during the tow – the Cambridge 302 was faster but at the same time more stable, and then during entire flight. I was smiling as I landed – perfect K-1, fast and accurate indications during all phases of flight." - Andy Smielkiewicz

"”to be able to see on the vario what “my behind” feels is great, to get that on a brand new glider – that has never happened to me during my almost 40 years of competition flying”… - Stan Wujczak

Mounting Tip
The probe should be mounted so the 2 tips are oriented horizontally - parallel to the wings
