gpsdude - 1/9/2012 12:26 The only problem with having training classes is that those who want to learn come. Those who just want to call when they can't remember how to set an AB line, will not come to the class. they will just call as usual. I had a customer that call 12 times in one day last year. Everytime it was to set a new AB line. This happend daily for 2 weeks until his sprayer broke down. This is an extreme situation, as some people rarely if ever call for help.
