No perfect detector or for that matter any perfect detectorist.

No matter the price or where its made or the company that makes it all units have their give and takeaways.

Have to admit although not perfect some of our fellows have learned their units well and excell.

Having said the above good luck in your choice and learn it well and you will excell also as they all will find treasure and a little luck and above all a good hunting area helps as remember if their is not a 10 point buck on the mountain you are hunting you won't shoot a 10 point buck and the same goes for the detectorist and that elusive coin or perhaps an expensive diamond ring...etc...

Dan, what are you trying to say, if you don't put the coil over it, you're not going to find it, that's were research helps the odds
