I had a Vibraprobe several years ago & I never could get the thing to read on the target (coin).---Had to be actually touching the coin with the probe tip before it would even sound off.-----If it's waterproof you are wanting, apply some Gaffers tape over the speaker slots on the Pro Pointer and it's (about) waterproof.----If it's reading off the tip of the probe that you want, "double trigger" (turn the Pro Pointer off & then on again when close to the target).---This de-sensitizes the probe & makes it read on the target closer to the tip (same principle as when you double trigger a detector).------Another tip is you can run a narrow piece of Gaffers tape around the seam of the screw on battery cap on the Pro Pointer.---This may help also although there is already a gasket on the inside of the cap.----One things for sure---by putting this tape around the cap seam, it SURE makes it easier getting it off to change the battery due to fine dirt getting in on the threads of the cap & locking it really tight.------Comparison of those two probes?---IMO, there is no comparison---Garrett Pro Pointer all the way, hands down.---It's the best hand help probe on the market right now & has been for some time (again, IMHO).---My wife & I have used them since they first came out & sell one once in awhile only because we want to replace it with another new Pro Pointer that is under warranty.-----BUT----I have never had to send a Pro Pointer in for repair, they are built like a tank & hold up excellently.-----------Del
