Thanks Rob, I guess I'm starting to see the value of the ID system. I was only using a basic beep and dig machine before I got this and had learned how to do most of my discriminating using my ears, but I was still digging most of my signals anyway, because I was doing all CW sites during the past year. I'm now going to be doing more coinshooting, because I'm getting my son into it and coinshooting is the best way to keep his interest and keep him safe until I can teach him what he needs to know about relic hunting (avoiding snakes, poison ivy, ticks etc.). To answer what Larry responded as well, yes I know that the meter is an approximation, I hope I didn't step on any toes with my statement. Guess it just seemed to me that its tough to glean anything that will form a pattern from such a variable data source. I understand the coinshooting use and it explains why I haven't had any real use for a meter until now. My main reason for wanting the White's MXT was the fact that it runs an all-metal Threshold and discrimination together, something you can't get with a Tesoro. Also, seems that there are more choices in coils right now for the White's than what the top of the line Tesoros have. If the Tejon had some of the same coil choices as the MXT I would probably have a Tejon right now. But, I'm starting to like the MXT so its all moot anyway.
