Probe:

For hunting for targets in grass, use a probe. A probe helps you pinpoint your target BEFORE you start digging. Best for those shallow targets. I use a carpenters AWL for a probe. Just be sure that your probe is not too pointed. It can damage a valuable coin if it is too sharp on the point.

Dig Trash:

Be sure to dig trash targets, especially if the place you are hunting is one that you will be returning to time and time again. It will make you more successful the next time you hit that spot. Some of those trash targets are good finds too! Like rings and tokens.
