How often might we pass up a low vdi which in this case was a 43, because of fatigue or lazy or both ? I wanted to share this example as to why anyone including myself as to never do this. Most areas I hunt are extremely trashy with pull tabs of every kind to tons of shredded cans. This class ring hit on 43 and locked on, but the tone was so sweet and crystal clear with no warble or crackle all the way out to the edge of coil. Having said that, so does in a lot of cases small pieces of flat can slaw. For me if the tone remains clear at different angles, by all means dig. One of the nicest looking rings I have ever dug was a small gold band with a ruby stone that rang 43. You just never know. I know this ring was not silver or gold. It had slmt stamped inside, not sure what metal that is.My wife researched the ring and found its owner. When she gave it to the young man whom lost it she said the gold was in his smile. Listen to the tone, for it says alot. GOOD HUNTING TO ALL
