With the Minelab Explorers, I also managed to find a few large coin caches in the fields. My girlfriend at a time, Shelly, and I recovered many 'goodies' including nice relics even at the 'hammered out' sites. I used the Minelab Explorers for nine years in total, and these machines were my primary detectors for Coin Shooting, Cache Hunting and Relic Hunting because of their two innovative features: a 2-Dimentional Discrimination scale called 'Smartfind', and a FBS (Full Band Spectrum) system with 28 simultaneously operating frequencies (from Super Deep 1.5kHz to Ultra Sensitive 100kHz). I also believe the GP3500 and expecially the GPX-4000 are getting more depth over the SD and ealier GP series.By Sergei UpstateNY, proficiency level: Expert, last time modified: October 7, 2020ĭuring my seventh metal detecting season, I bought a Minelab Explorer XS and, five years later, acquired a Minelab Explorer II which I used for four years. The GP series, GP Extreme, GP3000, GP3500 and the lastest GPX-4000 are much more sensitive to smaller gold and smaller gold at depth. The SD's with a regulated battery system like the Coiltek Pocket Rocket Li-Ion System will help increase performance and stability. They changed control box color from the Army Green to the Blue and some other minor changes. I think it means 'Version 2' of the original version. The newer versions are called the SD2100v2 and SD2200v2. Since the SD2100 & SD2200 were such good sellers for the price range, Minelab decided to keep them around. The next was the SD2200d, which was pretty much the same electronics as the SD2100 but had more features such as Auto Tracking, Discrimination. The SD2100 was the next detector built and was a big step up from the SD2000. This detector has been discontinued for a long time, but some still use it with modifications in Australia. The SD2000 was the first Minelab Pulse Induction (PI) detector built many.
