Hi , Recently acquired a SE Pro and I purchased the explorer /etrac book and read the manual briskly and decided to try it in my test garden. I ran the machine with the factory presets and did the noise cancel and discovered it would not hit my 8 inch deep quarter at all. My sov gt would hit this and i am disappointed or I am expecting too much from the machine with the preset program? I realized that this machine is definately going to have a learning curve but I was hoping to use it this spring at my farm field sites here in Pa. Thanks Ezra.
