Explorer SE Pro sensitivity 26-28
Upstate NY...varies from very stable in sandy soil, a touch noisy in your average dirt, to a bit of chatter in clay.
Virginia...their red mineralized soil is fairly noisy, more so than in NY but solid hits on targets stand out.
NJ Beaches...silent as a church in dry sand. Wet salt water beach sand with sensitivity about 26 gives fairly stable operation, higher sens chatters too much.
Pacific NW (Oregon/Washington)...pretty much a nightmare it hates the volcanic black sand. Noise, blips, cursor jumping around, even the X1 probe doesn't like this soil.
