| 250 Year Old Ivory And Brass Rosary Found. |
On June 23, an intact Roman Catholic rosary was dug from an excavation site at Colonial Michilimackinac, an 18th-century fort and fur trading village that's been reconstructed as an open air museum over the past 50 years.
The rosary — rare for being found intact — is approximately 250 years old...

You might remember the story I posted about the "ivory crush" a few days ago.

I've talked about using different types of metal detectors. Each metal detector has its own strengths and weaknesses and there will be times when one is the best choice and other times when another is the best choice. You don't need a lot of metal detectors if your detector is a good general purpose detector and you are satisfied with not getting the absolute last iota out of a detecting site. There are times when that is not cost-effective to go for that last bit. So what if you don't get quite everything. No biggy. Sometimes it isn't worth it. Sometimes it is better to move on to a more productive location.
There might be times though, when you want to make absolutely sure that your aren't missing anything. That would be when the site is producing or has the promise of producing something truly exceptional or meaningful, or when you are trying to find something like grandma's lost wedding ring.
I've talked about how to use multiple detectors in a series when you really want or need to do a very thorough job.
There are different ways to categorize detectors. Many people divide metal detectors in two major groups: VLF and Pulse Induction. That is a useful categorization. Each type has its own characteristics, benefits and weaknesses.
VLF detectors are know more for discrimination and target ID. PI detectors are more know for depth, and unfortunately or fortunately, depending upon what you want to find, sensitivity to iron.
Those are indeed two different types of detectors and there would be times when you might choose one and times when you would choose the other type.
There are some detectors that do a fine job on dry sand or soil that is not mineralized. There are some detectors that are not particularly deep seeking, but are OK for a quick scan or first pass. There are detectors that have notch discrimination or other types of discrimination that might be particularly appropriate at the time. There are detectors that do a good job of target ID. There are detectors that are particularly good on gold and other precious metals.
No matter what detector you use though, you can benefit by learning to use it well. I dare say that most people do not spend the time to really push the limits of each detector they own. That takes a lot of time and experimentation.
I'm not saying that you have to do that, but maybe you can learn a little more about your detector, and that little bit might make a difference some day.

I just took out some old finds that I never took the time to look at real well. Here are a couple small ones, each shown on a dime.
We still have a smooth surf on the Treasure Coast. Also some negative tides.
Happy hunting,
