Anybody try something like this?
I use their smaller version in my shop. I don't know how deep these detect to or how useful they would be with trees, but might be helpful if you know that you are working old hedgerow. Would be interested in any body's experience.
Thanks.

http://wizdist.com/lumberwiz.cfmThe Lumber Wizard III is the latest version of Wizard Industries' flagship woodworking metal detector. A powerful precision hand-held metal detector designed specifically for woodworkers, It helps detect small metal objects hidden inside new or used lumber. The new version features easier one-handed use, with automatic calibration every time the unit is turned on, and better false-positive rejection. Undetected nails, screws or other metal fragments can damage expensive jointer, planer and saw blades. Flying metal can also cause serious injury. Easy to use, the Lumber Wizard III helps woodworkers prevent equipment damage and personal injury. The unit includes a vibration alert, allowing use of the Lumber Wizard III in noisy workshops. The Lumber Wizard has received rave reviews from woodworkers and magazines across the country, and the new version is even better!
