Another newbie to this forum, but have been detecting several years. Originally a Qld'r but now reside on the other side of the planet. I hunt anything from -15 meters below sea level to 2.2 km above. 69 degrees north to 37 degrees south. -8 degrees Celsius and 43 degrees celcius above. The heaters I have and use are a GPX, CTX and excal II. Hope to post some interesting finds.
