CK: Pin Pointers are highly specialized, the correct one(s) for you will depend upon where and how you hunt.
On land or dry sand at the beach, I prefer the Garret Pro Pointer, especially to find a target in the side of a hole, as it detects off its side(s) as well as it's tip. It is easier to carry (more streamlined shape) and faster to pin point with (unless multiple targets are within it field(s). The led light really helps to see a target in the hole or a night.
On wet sand, in the rocks, or shallow water hunting with a float and plastic sifter, the vibra probe 580 is the pin pointer of choice. As it uses pulse induction technology, mineralization does not affect it , which drives the above Pro Pointer crazy (false alarms). You also do not have to worry about destroying it if you submerge it as it is also used for shallow diving. It is more precise as it only detects near its tip, and is more stealthy since it only uses vibration to indicate a target.
Even though the Vibra probe 580 uses pulse induction, it does not detect deeper than the Pro Pointer. You have to be slightly more disciplined when using the Vibra Probe as it can interfere with your main detector, and your main detector can interfere with it. It is not a big deal, You just have to be careful to avoid pointing either coil toward each other, or turn one or the other off.
