About J.B. Knowles, Inc.

The Chopper Spotter is made with care by J.B. Knowles, Inc.. Tucked among the hills and dairy farms of southwestern Wisconsin, it is an unlikely place to find a company devoted to producing machines for helicopters.

Founded by Jack Knowles on the principles of integrity, quality of workmanship, and value for the dollar, J.B. Knowles, Inc. is a 30+ year old company, incorporated in 1989, with a reputation for honesty, high quality work, and extraordinary solutions to design problems.

If you purchase a Chopper Spotter, you can be assured of a quality machine that works, and it will be backed by a company that values your long term satisfaction.
