Admin nuggethunting Posted January 18, 2010 Admin Report Share Posted January 18, 2010 Hello All, Personally I've never had any experience with a good GPR metal detector, but was curious if any of you have? I wanting to find out if a GPR can detect or show where there might be openings or tunnels underground? The depth to these tunnels can be anywhere from 5 to 20 foot in depth. Interested in hearing any information that might pertain to something that might locate these openings or tunnels. Thanks in advance,Rob Allison Quote Link to comment Share on other sites More sharing options...
spud Posted January 18, 2010 Report Share Posted January 18, 2010 Rob, there is a manufacturing business in Gold Hill,OR that manufactures GPR equipment. I know they make a screen that you drag across the ground which detects gold hidden beneath the ground - don't know all the particulars but this may be just the thing you are looking for. Some years back it was a White's metal detector shop but am not sure of the name now. If you could make contact with them I am sure they would be more than happy to assist. Hope this helps, Nugget ManHello All, Personally I've never had any experience with a good GPR metal detector, but was curious if any of you have?

Ridge Runner Posted January 19, 2010 Report Share Posted January 19, 2010 Rob What I've read they can do just what you want.There was one used down town at the Alamo ( San Antonio ) it was box type that you pulled along the ground and it would give a print out on your Laptop of what it seen.I've seen the cost but don't remember and like everything else it's gone up I'm sure.The only thing about this one is the ground would have to be smooth to get a good reading. Now if you just needed a two box metal detector I'll loan you one for as long as you need.Best to you on finding the ans.and what you want.

highbanker58 Posted January 19, 2010 Report Share Posted January 19, 2010 Rob There was a guy at the GPAA Stanton event last month with a handheld version .He went into the office and told Linda that he had scanned the area in front of the office and got a reading .He wanted to know how to get permission to dig it up, she told him to contact the GPAA office in Ca.

COLORADO BOB Posted January 19, 2010 Report Share Posted January 19, 2010 Rob,Check out these two sites, they will probably answer your questions for you.www.AccurateLocators.comwww.okmmetaldetectors.comBob T. Quote Link to comment Share on other sites More sharing options...
AMC Posted January 19, 2010 Report Share Posted January 19, 2010 Hi Rob, I'm familiar with Accurate Locators. It is a great product. If you want to see it work, we can head up to Vegas for a day. I am sure it will do what you want. Like Ridge Runner said, flat ground, ie bulldozer required. The model we were looking at to do the job is $25K, but it will give you answers.Jer Quote Link to comment Share on other sites More sharing options...
Digger Bob Posted January 19, 2010 Report Share Posted January 19, 2010 Robb, check this one.http://lrlman.com/Pages/Arc-Geo/Arc-geo.htmA friend of mine researched this subject for 6 months last year and finally settled on this one. Now, he wasn't looking for tunnels or voids. He wanted this to find deep nuggets. He demonstrated it to me in my office and frankly I was sceptical. But, he was sure it would work if he could just get it over some gold.So, last spring I took him out to some old patches I knew to see if there was anything deeper than I could detect. Turns out there wasn't...BUT... the machine WAS able to detect and clearly show 2 deep nuggets that I had planted for the test. He didn't know exactly where I had buried them but the screen showed them very clearly and he was able to narrow down the location to within 3 sq. ft. It was then a matter of clearing off some dirt and detecting. The difference in the readings between the nuggets and the ground "noise" was clear.And this is something that takes some practice to learn. Mineralization and iron targets can be identified more times than not.Anyway, this may or may not work for what you want to do, but it's worth researching a bit more and it's a lot cheaper than most out there.Digger Bob Quote Link to comment Share on other sites More sharing options...
D-Mac Posted January 19, 2010 Report Share Posted January 19, 2010 With the Minelab's on back order, has anyone had any experence with Accurate Locators? They have a SSP-2100 in stock, that is PI.
