  1. 1) TRINITYAU/RAYMILLS, you said the GB Pro works good in these rocks but have you ever tested the AT Gold and F75SE in your basalt, serpentine, and volcanics.? Steve H. explains he likes that the meter on the GB Pro which always runs in discriminate mode even when the detector is in all metal prospect mode which is like running 2 detectors at the same time. 2) But my question to anyone is, can the GB Pro be set to notch out certain numbers.? For instance if a certain hotrock(or basalt volcanic) is coming up and can that number(s) be knocked(notched) out to eliminate it.? If not then instead of the GB Pro maybe it would be better to use the F75SE(or AT Gold) to notch out hotrocks(or basalt volcanic or small ferrous iron trash) and still see the meter in all metal prospect mode.
  2. Good idea Tom, but like Pete said put foam or some other sort of cushioned pads on top of both your shoulders sewn-stiched into your clothing. That way you can rest either your metal detector shaft or digging pick on your shoulder. And yes Flak, it is a good idea to put foam underneath the detector control housing box(installed between the housing and cover) to protect it from shock while setting it down on the ground. Just make sure it is installed properly so it does not tip over and fall on is side. In Victoria, Australia back in 1989 I went detecting with a fellow(Bob White, manager of the Elm Motel in Bendigo) put very dense thin foam, about 1/4" to 1/2", like roll-up backpacking bed matt. Wrapped almost completely all the way around his Minelab GT-16000 to protect it and prevent damage from bumps and shocks. I was using the Fisher Gold Bug at the time.
  3. Or just order-get a 'solid skid coil cover' for a Coiltek Blitz 14x9 for $24 from Razorback Coils who makes them: http://razorbackcoil...ts/show/2822951
  4. Gary(Grubstake), get well very soon. Jesus Christ is Lord and God raised Him from the dead, for us to be saved in eternal life.
  5. For myself I am waiting for the release of a CoilTek GoldStalker 18x12 Blitz or I was hoping maybe they will make a 24x12 size Blitz. I do not want to get into trouble here but I think the present 14x9 Blitz is a bit more sensitive than same size the NFA. I was told the 30x7 NFA has about the depth of a 8" round. Also this is what one fellow said about the 30x7 on another forum: Gday I have used the 30x7 NF patchfinder, I still think its a good coil for the purpose it was designed for, and that is covering lots of ground, they are super sensitive to small pieces of everything, lead shot, steel shards, but you really have to select the type of ground that you use it on, as far as depth goes I think that if you are working ground that has some depth to it you would be better off using a round coil. By selecting the type of ground, I mean flattish, even clean areas, because they are such a long coil they tend to get heavy so use it in combination with a hipstick, you may only manage a couple of hours swinging with it without one, if you are trying to cover areas that are scrubby, rubbly, or in any way overgrown or strewn with sticks you will find yourself lifting and adjusting the level of the coil continously, this can become tiresome and annoying. The very nature of the coil means you have to swing it close to the ground, it is sensitive and designed to pick up indicators, small pieces that will possibly alert you to a patch, but as its long and thin the depth ability although reasonable is by no means exceptional, so you need to be able to get it as close to the ground as practicable to get the best out of it. I am not trying to put you off this coil, as like I said its good for the purpose it was designed, or if you have some areas in mind that it would be suitable for, if you are contemplating it for a general use type coil, then I would probably have to say that something like a 17x11 or a 24x12 eliptical would be more practical. cheers stayyerAU
  6. So far my favorite size choice is the NFA 17E & 24E for an all around coil, but I cannot wait to see if a CT GS 18E Blitz comes out is what I would like to have. I do not want to get in to trouble here but from the reports I have heard I think that new 14E Blitz coil is slightly better than the same size NFA coil. The Commander 15E is good to but too heavy. I honestly cannot see why JP likes a round 18" as a general all around everyday use gridding coil.? Because instead it is a specialty coil for bigger nuggets at depth and the round 18" has less depth on nuggets under about 2 grams which are the most common nugget sizes, and nuggets bigger than this that it excells at are much too rare to be specifically looking for them. So to get the maximum depth on nuggets under about 2 grams coupled along with good ground coverage then the Elliptical coils I mentioned above are best along with the NFA 14E and CT GS 14E Blitz. The 11", 12", and 14" rounds are also good but I prefer ellipticals for more coverage and better pinpointing.
  7. Then do not take LSD when you are detecting then your luck might improve and also you might see snakes that are not there at happy ridge, but please do not take it at anytime and instead stick to beer beeping or a little whisky mixed with water or ginseng. I do now how V...(iagra) would help with detecting either unless it gives more stamina.
  8. I do not agree with JP that round coils have more depth(over elliptical coils) due to they accept the return of the pulse signal better. But I think rather the depth depends on area of the magnetic field. I also do not agree with the formula for an elliptical where, length + width รท 2 = equivalent round, although it is a common held opinion. The way to tell the depth of an elliptical coil as compared to a round coil is the area of the coil. Area calculations: round(circle) Area = (pi is 3.14) x r(radius) x r(radius) elliptical(also known as an ellipse or oval) Area = (pi is 3.14) x r1(radius of width) x r2(radius of length) (Another formula for Area of an elliptical I heard was: length x width x .8 = Area) Someone explained a 12 x 24" has about the same depth as a round 16". Also someone explained something like this: The bigger the coil then the deeper it will detect the bigger nuggets but the shallower it will detect tiny nuggets. The smaller the coil then the shallower it will detect bigger nuggets but the deeper it will detect tiny nuggets. I have a NF 12 x 24" and 25" monos. It depends on surface area of the gold facing the coil, but on typical nuggets about -2 oz and under there is not a huge advantage for a big round coil over a big elliptical. But on about a bigger +6 oz nugget a big round coil starts to shine as much better. If I were you I would have bought the elliptical 14 x 24" instead of the round 22". Yes the 22" will pick very small gold on the coils edge but the 14 x 24" has more sensitivity(depth) to smaller gold and the most depth you want for the size of gold you are looking for, the best of both worlds. This is my opinion and others may disagree. Someone else also explained that there is almost no depth advantage on coils over 18" round, just more ground coverage. Yes he is right on the most common(over +99%) gold sizes on the goldfields, unless the very rarity if the gold gets really big then there is an advantage of coils over 18" round.
  9. I was told by Minelab the Sovereign GT is not good on gold smaller than about 1 gram. Yes this is way overdue. Minelab should put the GPX-5000 technology in to a lighter-weight and more compact E-Trac/Safari housing with an all self-contained Li-Ion battery, signal enhancer, and built-in external speaker being an all-in-one, grab and run unit. With a factory carbon fiber or fiberglass upper shaft. Yes I support the military greatly too with much thanks including our freedom is not free with great sacrifice, after growing up with vets and my grandad with years of very long time direct active war service without getting killed was a miracle, and follow closely WW-I and II stories on the Military Channel. But they have also done some mistakes. Sadly saw the video of the Apache helicopter machine gunning a bunch of innocent civilians and Reuters journalist employees on the ground mistakenly thought the camera shoulder bags were AK47s and a telephoto lens on a camera was a RPG, mowing them down along with a van, with two young children inside who were also hit, that was picking up the injured. Not intentional but a very serious thing with very bad judgement by the Apache pilot not to circle around with the helicopter to have a look from another angle at the camera bags and telephoto lens on a camera. Steve H., you have contacts then pull strings, (in your off-season winter time)work with either Whites(in Oregon), Fisher, Garrett, or Minelab(through Jonathan Porter who knows Bruce Candy, etc. personally) to design a new VLF detector. Chris Ralph may also help you. Thank you for helping us in advance if you do.
  10. Yes the Desert Fox and Gold Miner are good but I heard the two best auto-panning spiral wheels on the market are the Gold Genie and the Gold Screw. http://www.jobewholesale.com/gold_genie.html and http://www.goldscrew.com/ and http://www.49ermike.com/dc/dcboard.php?az=show_topic&forum=181&topic_id=91535&mesg_id=91535&page=
  11. Thanks Del. I think Rob Allison made a post some time back about someone who bought fake chinese GPX-4500 or GPX-5000 unit(s). So you never know if those cheap GPX-5000's are fakes with VLF guts in them. Buyer beware and be careful if you are not buying from a genuine certified dealer like Rob. No the SD-2200v2 did not have Dual-Voltage Technology as far as I know, otherwise it would be called a GP-3000. So the v2 may stand for version2. If it is true, this guy is suppose to be able to modify a GP-Extreme to make it about just as good as or better than a GPX-4000 or GPX-4500 according to Jack Lange: http://www.detectormods.com/
  12. "GPX-5000- $4,000+ (average was $4,284.80)...Another thing that surprised me, was somebody recently scored a GPX-5000 for only $3,000! Almost to good to be true!" Paseclipse (Del), is this information you gave above correct, or did you make a mistake and mean a GPX-4500 ?? I think Minelab's next step in the near future should be putting GPX-5000 technology into a more compact, much smaller Safari - E-Trac sized housing with a built-in Li-Ion battery-booster under the arm rest and a factory built-in external speaker all totally self-contained in a grab and run lighter-weight package. Of course the headphone-external speaker and bungee hook-ups are there but optional. Remember just before they were discontinued, the blue boxes SD2100v2 - $1,198, and the SD2200v2 - $1,898 were selling brand new for these prices. They did not have Dual-Voltage Technology so what does the v2 stand for, version2 ?? Also remember the GP-Extreme had different sub-models having some of them with a problem, when the problem was sorted out then others were good ones. I think this can be identified by the serial numbers.
