I'm reading about the new 18in. EXcellerator coil on Kellyco's Metal Detecting site and their saying it can be used on an MXT and find dimes at 18in. and quarters at 22in.. Has anybody tried them and are these depths inflated? I called Whites and they said their 14in. coil will increase depth by about 15% over the stock 91/2 coil so I can't see how 4 more inches in coil dia. would give you 8 to 10 more inches in depth. Will these bigger coils miss smaller targets like a half dime more often than the stock coil?
