Borgelt B40 variometer / audio / averager * NEW * UNUSED * MINT *

New, unused Borgelt B40 audio variometer and averager. Comes in original protective cardboard packing. 80 mm size. Scale is in Knots Bought new from Wings and Wheels in 2001, never unpacked or used. This came with the PIK-20 glider I had bought -- I didn't install it since the existing vario was connected to the TE probe and flight computer and worked well. Includes: - Installation and owner's manual - Comes with attached speaker and 9 V battery connector - Original sales receipt This is an excellent device, no self-respecting sailplane should be without one. :-) Guaranteed to improve your thermalling, cross-country and competition performance!
