I don't agree with getting the Garett ProPointer, it's cheaply made. You get what you pay for. I keep hearing that all they had to do was shrink wrap the internal wires, and put a grommet in the battery cap. It would have cost less than 50 cents.
It works great for a little while, then plan on going without one for two weeks while they send you another. Mine lasted less than 8 months of gentle use, no water contact at all.
Now mine falses so bad it sounds like I have a quarter touching the tip when I barely press the dirt; I have 2 quarters in the battery cap also.
It's worth the extra 35 bucks for the Minelab.
