Jewelry testing ID numbers

[tvr]

Some cabin fever testing with the F75 LTD:

Thin 14K gold chain with small clasp. Bounced between 1 and 6.
Small 14 K gold pendants that are worn with that thin chain ID as 16 and 18.
Wife's 18K ring with mounts for three stones ID'd at 30.
14k bands of various thickness and diameters ranged from 23 to 46.
Small 10k signet came in at 34.
Small silver chains with no pendants came in around 17 to 18. Good sized cross pendant from one of those chains ID'd at 76.
Silver rings ranged from 46 to 81.

Was running sensitivity at 20, BP mode, no disc. Any higher sensitivity and the ambient noise lit up the detector. With these settings in a noisy indoor environment I could get stable, repeatable ID's on nearly all the targets at 6 to 8 inches. The biggest ring of the bunch could ID at about 12 inches. The small gold chain could not be seen further than 2 inches from the coil. The small silver chains were good up to 4 inches.

Just as an addendum; the small gold chain could not be detected further than about 2 inches at all. All the other targets could be detected much further from the coil than the approximate distances posted, just that further than what was posted, the ID numbers started bouncing around.

I've got all compact fluorescent bulbs every where, ceiling fan, computer and TV all very close to where I have space to set a detector up inside to try some tests. I don't turn them off to try tests inside. All the noise sources don't help the detector do it's job.

The F75 LTD is a very good detector. Blows away my other detectors in most places and for most types of hunting I've done.
