Pathfinder V3 two box metal detector and hot rocks / iron stone
With the Pathfinder two box some big hot rocks may be audible and others not. However if you are looking for a 3+ meters depth, there is no detector that can give you just that and no hot rocks and/or false signals.
How to recognize large hot rocks with the Pathfinder V3 two box
The difference between Nexus Pathfinder and all other brands regarding the big hot rocks is that with the Pathfinder hot rocks are recognizable by giving a negative signal response (sinking the threshold level) that is completely different from metal responses, while the other brands sound the hot rocks as metal targets.
