Had some rainy nights lately so I finally did something I should have done a lond time ago! I did a complete air test on my ACE 250. I highly reccomend the experience because I learned alot while doing the test.
A couple things I would like to mention up front:
Keep in mind that the detection zone on the ACE 250 looks like an upside-down Hershey's Kiss. That means the deepest detection area is only small point in the ground.
The test was done in All-Metal mode only. I have been using this mode more and more lately. It helps to really give a distinct tone among all of the other interference.
The coins used were all pre-1964 coins. No zinc Lincolns or clad was used in this test! Only coins that you really want to find
All depths are in inches, sorry to all of our metric friends.
Laslty, any depth with a * next to it means that the tone was only heard on about 50% of the passes under the coil. Any of the * marked depths became consistent if I moved 1/2 inch closer to the coil.
Heres my chart...enjoy!
