Long Range Detector vs Metal Detector
Long range detector is a tool. A metal detector is a specialized tool and has a specific job that it can accomplish.
Rarely does a specialized tool multitask into the regions of other similar tools. A detector that operates to find metal or treasure over ten feet away (long range) from the burial place is a unique piece of equipment. IF IT WORKS it will save hours of digging, diving or just searching for a treasure that has already been taken or was never there in the first place. A metal detector on the other hand is very handy if you are digging and your treasure is small like a coin and can hide in a shovel of dirt. The metal detector will find it immediately. However, if you are trying to find a coin or a bullion bar that is over 15” deep and you are working with a metal detector that is under $1000 dollars there is every chance YOU WILL NEVER FIND IT….
