After complaints from those who normally fly without much of a panel, in July 2013 I came up with a contest that ran for 9 days (2 weekends plus M-F) and only allowed one electronic instrument: a digital turnpoint camera.
The turnpoint photographs would be evaluated and I'd use SeeYou to decide the winner, handicapping the gliders.
NO radio, electric vario, moving map, transponder, FLARM, SPOT (etc) or even cell phone use until the pilot and crew were reunited. Batteries were allowed to be carried as ballast only. Communication for a landout had to be by land line phones, both pilot and crew.
There was a prize, worth about $500.00.
Nobody entered.
I invite others to try the same.

Personally I always liked the red and green pellet vario. It made no noise so it let you enjoy the silence of the 2-33.
