Minelab Explorer se pro

I agree, the Explorer SE Pro is an excellent machine. You have to be willing and able to make adjustments to the settings though. The new ones are coming with a factory preset gain of 8. This is too high for any type of soil with mineralization or junk like rusted roofing tin scraps(someting you find alot of around the depression era homesteads). I was chasing my tail for the first several outings then I dropped the gain to 6 and now I can hear the difference between a good signal and trash. Even a good signal at depth is far different than a mineralization signal. Sensitivity is also very important as this machine can get very deep. I found a 1" dia x 4" long galvanized pipe at 22" down with sensitivity at 18. And I also found a wheat penny at 6" with the sensitivity at 10. So, if you are hunting a park, you can turn your sensitivity down to say 12 or even 8 to get rid of signals that are unwanted and concentrate on the items that you will actually want to dig. Likely you aren't going to want to dig a 2' hole in a park anyway. When you get out to a wide open area where you can dig deeper without problems, you can turn your sensitivity up to say 25 or more and turn your gain down to about 4. This will turn down the volume of tiny items or trash and give a more definate response to larger items and ones that are closer to your prefered dig range. This will also give a better ID of the target. Just my $.02.
