Hi everybody - after using a cheapo GP pointer for several months, my wife got me a Garrett Pro Pointer from Kellyco for Christmas. Admittedly sometimes it's on junky signals, but when I try to use it it often chirps so quickly it almost sounds like a steady tone,and keeps it up when it's moved back and forth in the hole. Not so bad on the few coins I've dug since getting it but for the most part I have to switch back to the GP to find the target. Do you have to turn the sensitivity down every time on these? (Which I haven't got the hang of yet)
