I have to give my 2 cents. I've been metal detecting for many years, and through the years I've had many different detectors. Whites, Bounty Hunter, Tesoro, Minelab. Let me start by saying back in 1986 Bounty Hunter came out with the first Big Bud, now I'm not talking about all the other copy's of the Big Bud that were produced after the original. The original Bud was a great little machine, found alot of coins and gold rings etc. It had a meter to let you know before you dug the target up what it was, also a depth meter full discrimination.(hang in there with me I'll be getting to the coin master) But what I liked about it was it had what they called LOUD ALERT. this feature was great no matter if the target was deep or shallow the sound would always be loud. So because I was injured a few years ago I got rid of all my metal detecting equipment. Now feeling better I decided to get back and give it a try, so I purchased a White Coin master, Well let me tell you for the money this Little machine is a big bud reincarnated, I went to the beach here in Fl. at this point in time there is to much sand blown on the beaches, you really would be lucky to find anything. I was digging dimes up at 10" with no problems green quarters up t 10" to 12+ deep in an hour or so I pulled up 42 coins all in the dry sand. And like that old Big Bud no matter how deep the target was you didn't have to listen for those faint signals. UNBELIEVABLE MACHINE. For the money you can't beat this detector. very deep, very accurate meter readings, the all metal pinpoint is right on target. all in all great machine for the money.
