Right now we pretty much dig everything........pull tabs, bottle tops, nails, you name it.....good practice. I still need work on the detecting, but I am darn good with the plug.
Watched a youtube video where you lay a rag next to the target, cut the hole, lay the plug on the rag, any loose dirt goes on the rag....find the target put the loose dirt down and put the plug back....pat it out even....property owner came out and watched for a bit and really appreciated taking care to leave things looking untouched.
