OK, The one thing I've learned for certain in my 5 yrs. of Mding is that nothing is certain. Had a little head scratcher today. After a factory reset I put my settings back in Park 1 and Field 2. Doing some air tests to check my tones I noticed one of the only two war nickels I've dug this year sounded completely different. The 45P sounded with a higher more melodius 12-13 and the 43 P came in with a lower flat tone with numbers showing 15-16. Not just a slight difference, If you heard these tones in the field you would think two different targets for sure and the numbers would tell you the same. Now both nickels have been cleaned and have about the same amount of detail. Comparing with two recently dug Buffs they rang 12-13 and sounded the same as the 45P. Park 1 the same. Park 2 50 tones still a big difference. Went into the warchest and pulled out 10 43 P's. 3 of them had the low flat tone with 15-16 numbers but the other seven all rang louder, higher with 12-13s. Ok I understand variables in the field but there are no variables in an airtest with the coil hanging of my dining room table. By the way sensitivity was down to 12 in the house. And all the other coins I tested came in right around where they should be. Gentlemen your thoughts, please. Mark
