NEW! Ayrstone's well-known DVD entitled "GPS Guidance and Steering for Agriculture" is now on YouTube.

In a very short time, Ayrstone's GPS expert will teach you everything you need to know about GPS and steering systems so you can evaluate and purchase the best system for your farming operation.

Whether you operate a large farm or just a few hundred acres, wherever you are in North America, this DVD is an absolute necessity before you buy a GPS system for your farm equipment. An investment of a few hours of your time can save you thousands of dollars and hundreds of hours of work.

This video was produced by industry "insiders" who want you to know exactly what this revolutionary technology can do and how to get the best possible deal when you go to buy it. The information on these videos is completely unbiased - none of the GPS or vehicle manufacturers were involved in it, and Ayrstone is not associated with any GPS or equipment vendor.
