Steve,
I experienced the same problems Al mentioned in his post below. Our claim is in Northern Nevada, in some patches, the SD is useless. I have seen a Lobo LST operate on ground too hot for the SD 2100, that made me real happy. After we scrape the first couple of feet of overburden away, seldom is there a problem with iron, or trash, the problems stem from increasingly heavy concentrations of black sand and alkalis. Maybe the machine exported to the states is set up differently, who knows, some manufacturers build different machines for the land of Oz.
In Nevada, the Lobo LST handles extreme alkali and mineralization better than the SD 2100, or XT 17000. Al is telling the truth, I felt a little foolish seeing it for myself, and having my nose rubbed in it. I too, would appreciate any info you can provide re the LST in Western Oz. I'm having a hard time justifying the expense to upgrade the machine to a SD 2200, based on "their" claims. Read the specs at finders.com/ Al made a good point about the new iron discrimination in the metal detecting forum, you might want to read that post.
The Fisher I refered to, is a JW Fisher Pulse 8X, with a 10" coil. In extreme grounds, it will out seek the SD 2100, try it, no hype! Take both units to a salt beach, bury a nugget in clean dry sand, keep adding and leveling sand until one machine runs out of range. Measure the depth and continue until the music stops. FYI, by placing the nugget in a plastic cup, you can use a marked 1/4 wood dowel to measure progress (place a plastic poker chip over the target, it makes the cup bottom easier to hit).
In clean beach sand, 50 yards from the surf, the deepest I could hit an 837 grain nugget was 12-13 inches with the SD 2100, using an 8" coil. The XT 17000 fell off at 11" with an 11" coil, at 6.4 kHz. The Pulse 8X? 18-19 inches no matter where I burried it, using a 10" coil. One strong feature of the PI, it reads the same in air, water, or solid rock, and it only reacts to metal. The PI isn't a replacement for VLF's, its just another useful tool that works when they fail.
I couldn't check the SD 2100 on the wet beach, it became too erratic and unstable. This is not a commercial for the Pulse 8X, I plan to buy a PI, but not a Pulse 8X, there is a machine built in Miami that is considered the absolute best ($2500). I will say this for the Pulse 8X, with a 16" coil, it will find gold deeper than you want to dig by hand! Thank God for Case backhoes! I will provide results on the Pulse 8X - 16" coil when I get a chance. I could guess, but that wouldn't be accurate.
We will be in Western Australia from October thru December, near Yalgowra, west of Meekatharra, if the old Holden is still running. If not, the beach at Perth always "perks" my interest! Australia has the best beaches in the world, where do all those beautiful women come from? The sand and water ain't bad either, mate!
A few years back, I stopped by Arizona Al's shop and he was telling me about PI's, nuggets, and heavy mineralization, I didn't act on it. Al was pushing the Lobo back then, and I was skeptical. I pay closer attention now.
