I probably am the only old timer (70) who criticizes the PINPOINT feature found on many detectors such as the DISCOVERY 3300 which I owned for a short while and thought the PINPOINT feature useless. "Why?" you might ask. My answer: I started with detectors that didn't have a PINPOINT feature, just DISC, ALL METALS, and TR. As long as you have ALL METALS you don't need a separate PINPOINT. You are either in DISC or ALL METALS.
When you are in DISC and get a solid signal, you switch to ALL METALS and never mind the X method. Just simply detune the detector constantly moving the coil to get the strongest signal until it's almost inaudible. At that point, the target is right smack dead under the coil's center. And if it's a shallow target you can put the probe in the center of an open coil and probably touch the target if it's a coin. If it's a ring, you'll probably go right through it! That was how it was for me for over 20 years before I retired.
I never used the pinpoint feature on my 3300, just switched to ALL METALS. I now have a BH LAND STAR and I use DISC for hunting and ALL METALS to pinpoint.
"Progress" doesn't always result in improvement.
