Detecting a large tract of land for an iron object.

Morning cache: Have you ever mada compass as a kiddie?

I know how to make a generic compass by magnetizing a needle, but it wouldn't be anything to brag about. :-[
 

For a large swath of land...

I would recommend an underground scanner utilizing four ground rods. Depending on overall mineralization and moisture, the carrier wave on mine can cover about a half of an acre (on average) at a time and discriminate well between steel and nonferrous metals... water and tunnels as a bonus.

Also, I have Pulstar 2 with a one meter coil encased in square PVC pipe. If you wear shoes with no metal, empty your pockets, and hold the electronic detector above your head, you can operate it alone with shoulder straps. Same ability to discriminate between ferrous and nonferrous. I hit and dug a steel target six feet down with it so depth is a-okay too.

Best of luck

Are you talking about the GPL?

Yes. Mine is an older model that reads resistance by the speed of the wave traveling from one rod to another as well as a gauge that attempts to guess what the suspected target is. Water - tunnel - inert ground - iron - brass - gold - copper - silver. A conductive target will hone the wave in a direct line from the sending rod and deflect to the receiving rod and a nonconductive target will further scatter and delay the wave's travel.
 

Isn't a GPL the same as a LRL? :icon_scratch:
 

Cool. Thanks, Cache Crazy.

I would think that the search of "several acres" would not require a two-box machine--since the area was so small...either compass and MD or perhaps even MD would be sufficient, unless the area had heavy trash...


Best Wishes,

A long range locater is a good option - assuming it works. When I bought mine, I had the owner of the company (Claude Cochrane) selling the equipment meet me after I had arrived not far from his house in Kentucky and buried my target coin in a park/attached cemetery of about 15 acres. It was 90% gold, 8.33% copper and the rest silver. I also buried three other coins smelted at 90% gold and 10% copper. Lastly, I had two pure gold targets in the same field. The latter five targets were to create interference.

His claim was that the equipment he was selling could discriminate between these three and after he located the target coin in less than 5 minutes, I bought everything the guy was selling.
 

Now that some time has passed, I just wondered if the farmer ever dug up the Steam Tractor or what is called a traction engine.
 

I am interested in the difference between a GPL VIII vs a lorenz or a 2 box MD, what are pros and cons?
