Last week I took the pastor of my church out detecting and let him use my X-Terra 505. As we were moving along he said that he had a reading and began to dig. He saw an old 7-up can about two inches below the surface and continued to dig it up. He grabbed the can, and as he did a big old tarantula ran out of it and jumped onto a cement border about three inches away. Obviously he was somewhat taken back. I’ve attached a picture below. I never realized that detectors can pickup on tarantulas!!!!!
