Collision avoidance device

SureCheck Aviation now offers a low cost proximity detection device that's
suitable for glider use. It receives transponder transmissions and
indicates nearness of the source. This unit is the size of a credit card
and operates on batteries. Velcro it above your panel and you're done.
This should be a major help in commercial and military traffic areas. See
it at my web site, www.oxaero.com.
