So today I decided to take my old SD2200D coupled to my 17x10 coiltek mini ufo coil up a local creek that I has been very heavily detected. I also took along my Fisher gold bug with its 5 inch coil. My plan was to walk right up this creek detecting with the SD on the way up and then the gold bug on the way down. We have not had any decent flooding for a looooong time so any exposed bedrock has seen multiple coils by now. My plan was to target deeper areas with the Sd and then try to find some missed crumbs with the gold bug. So long story short I got a 0.6g and a 1.2g piece. Both were on the edge of bedrock areas where deeper gravels start. Having not had the sd and it's selection of large coils that long I was surprised at the comparatively small pieces it was able to detect.(when compared to the massive coil). I ran out of time to use the gold bug much but I've used it a lot in this area before so wasn't expecting much.
Thanks for looking!
I just bought on eBay this coil minelab "super goldsearch 18". I bought it as a project for the tdi.
I showed it to a friend with many years in the hobby, he told me that he had seen it many years ago and that he remembers it for the "beautiful design". It looks like the lid of a garbage can.
According to when it was manufactured, it was a very expensive coil, designeg for the SD, but it has no more information.
Does anyone know anything about this coil?

Anyone know where I might get this part? Thanks. The hand hold broke off.

If anybody wanted to waste their time by crawling around the various forums under my handle lytle78 – they would probably see that I have expressed a certain skepticism about Minelab and the pricing policies.
On the other hand I am no dumber than your average rock and I knowledge that their current top-of-the-line model GPX 5000 is probably the world's greatest gold detector.
Not being an accomplished gold detectorist or prospector I'm not in a position to shell out five grand or thereabouts on the metal detector.
Last week and opportunity presented itself to buy a minelab SD2100 at an attractive price with an assortment of nice coils. It arrived today it works fine and I look forward to playing with it in my ground here in gold canyon Arizona – where there is no gold – and comparing it to my White's TDI.
So far only one thing has struck me. Although it's noisy as hell here in what are now becoming suburbs with underground electric service and lots of cell towers – I could by moving the tuning control around find a reasonably calm threshold.
When I tested the various coils on my 1.5 grain 18 karat gold bead – in air test – I got a very disappointing response. Needless to say having spent a nice piece of change on this thing I was disappointed! I then laid the test bead down the ground in the clear spot and found that the response was much better with the bead on the ground than waving the bead across the coil with the coil in the air. Clearly this requires further investigation and may be pretty good evidence for the old saw that PI detectors don't air test all that well but they do a lot better than the ground.
Standby for more data – and feel free to ignore it all if you see that is something I posted. Cheers to everyone - really like the new forum - look forward to learning a lot.
