blowfly - This is the way I look at it. Never quit when you hit a whisper target - or any other target for that matter. If you have to get a 12 foot ladder to slide down into the hole and hire your cousin to stand at the top and carry buckets out with a rope - do it! Other wise you'll wonder the rest of your life - did I leave something valuble down there?
I was in a city park yesterday and was swinging my coil out around this hollow tree, [which was about 2 feet in diameter] and was picking up a faint hit. I put the coil onto the tree and lo and behold it got louder. Well, got my thinker going, [which by the way doesn't work too good anymore] and decided it must be a heavy wire or cable that was put on the tree years ago and probably grew over the culprit leaving it invisable. There was a slit about 8 feet high on the tree, so I reached into the hollow and bent my wrist to the right and pulled out a metal container about 12 inches tall by 2 inches wide. Inside was a note that it was hidden there for purposes of a global positioning exercise. By the way, I own a Tesoro Vaquero also. I could pick up the metal tube all the way around that hollow tree, which I felt was pretty good detecting power.
I placed the container back inside the tree and started to walk away, stopped and decided to go back, remove the container and check the tree again. Having done so, I discovered another signal on the East side of the tree, only. I reached inside the slit and dug out who knows how many years of leaves and an old cigarette pack. I pushed my pin pointer inside - as far as I could reach and got a signal. Now my cubit probably isn't as long as yours, and could not pull any more trash. From what I can remember, a cubit is the length between the middle finger and ones elbow. Anyway, there is some dead wood - about 9 inches on the East side in the hollow close to the ground. I could saw it out and reach in farther, but, it's on city property - in a park - I can't do that! I'll have to figure out something but I'm not giving up even if it's a large piece of tin foil that I come up with. Then I can invite some of my heathen relatives over and they can feast on some real swearing - never give up! Dimesworth
