I love your Barber. It is one that I enjoy a lot. On the subject of machines. After all my years of playing, I have to giggle a bit. There may be a few tests that can give a decent average as to a particular brand's abilities. BUT, when it comes right down to it, there are just too many variables to either pin it to a machine's prowess or lack thereof.

A person tries a new machine, they're admittedly a little confused by the newness so they are also a little more careful about letting a target get by. So, what happens? They find, more. Eureka, hallelujah and praise be! I FINALLY have the holy grail of detectors! I know because I've been over and over and over this very spot! I can even see the signature I put on every hole I dig! AND , here, with this glorious new machine, I've found this coin! All problems are solved! The moisture, the minerals, the atmosphere, over head wire interference, radio waves, microwaves, angles of the detector's head, headphone to machine reactions, human ear differences on frequencies, grass height, near by garbage(which can be below, above, alongside), reaction time of the processors, battery strength/type, possible micro shift of the batteries in their chamber, attack and speed of the swing, targets on edge, hearing a very loud signal just before hearing a softer one(human ear recovery time) and the biggest one of all! Assumption by the user. Catch my drift?

My best suggestion to any dectectorist trying to increase their skills, work on the one thing that is constant between all machines, you. The rest will fall in place. I have hunted with a very early Radio Shack Kit model. It was sooooo bad I had to swing with my thumb on the tuning knob so I could tune it as I was swinging! AND, I out hunted a couple "experts" with their high highfalutin machines. On their own ground! Could I do that consistently? Of course not! LOL But, that I could and did says something about equipment. This is not just for the original OP or anyone else who posted. It's also not a defense of my AT or a poo poo-ing of anyone else's machine. It's just some information about detecting that I don't see people considering when trying to decide. Use what you want and just throw the rest away!
