The Explorer will work well for Cache Hunting Fredrico.
It will depend mainly on what the ground conditions will be when using a Big Coil. If you were to use a 15" WOT Coil for Cache Hunting, it could work well but if the ground is really cluttered with a ton of Iron, then it may not. You see...using a Big Coil can have it's dis-advantages out in the field. If the ground has too many targets present, especially with Iron present, some targets may get masked with a the Bigger Coils. You will also loose Depth due to this.
If you ran in All-Metal, Ferrous Tones...it may help but you would have to go really slow and listen to all the targets in the ground and still I think the Explorer would still miss targets that are too close to Iron.
It also depends what the Cache might be stored in and what is all in the Cache for Coins. If the Cache is stored in a Tin, then you will have to dig just about anything that pinpoints large in order to find it. If the Cache is buried in say an old Cream Crock, then it will be no problem. You will have to remember that other denominations of Coins in a Cache will also throw off the ID of the Target so everything that reads good you would then have to dig.
If the ground is full of Iron, I would try and use the Stock Coil first so you have a good chance at maintaining Depth and a fair chance at separation.
I have dug up a few Cache/Pocket Spills before myself. If there is a lot of Silver present, then I would look for an ID of an Indian Head Penny or possibly a little lower if that is what the Cache consists of.
If Gold is present, then the ID could just about land anywhere which is why it would be a good thing to dig all good signals.
I hope some of this helps you out Fredrico and if you have any other questions or have more details of what kind of Cache you maybe looking for and if the ground is full of junk, PM me and I maybe able to help you more with what to look for in ID and what size Coil could work the best. Good Luck and HH to you.
