or should i say my wife's new mxt 300...I received it about a week ago and due to my work schedule, I was unable to assemble it until yesterday. She couldn't wait to get her hands on it but of course I had to read the instructions and try to interpret them to her. Our first time out was a learning experience... We detected our own yard taking turns with the machine while the other did the digging. we got alot of erratic readings and did alot of digging and didn't find much. I'm sure it must have been operator error...I'm guessing?? I followed the quick start instructions. We even buried a quarter, a dime and a penny at approx. 4-6". It took us awhile to get it to read the quarter and dime but it didn't read the penny.( it was slightly on its edge in the hole) I know I need to get the mxt edge book but in the meantime can anyone offer any suggestions? I would greatly appreciate it. thank you.
