IMHO you should seriously consider the Tejon or the Vaquero due to the inclusion of the manual ground balance. They don't have the meter, but with a bit of practice and experience, you should be able to get a pretty good idea of junk versus good targets by use of the discrimination. I have a DeLeon and the areas I hunt with it the ground is relatively mild so the preset GB is not a problem, but then again I have several other machines that have either a manual ground balance or true auto ground balance so I have those options when I need it. The Cortes does have manual ground balance in the all metal mode, but is preset in the discrimination mode. The DeLeon, as I understand it, has two ground balance presets, one for each mode. Bottom line in my opinion is if you're only going to have one machine, either manual GB or a true auto GB is the way to go. If you happen to look at older, used models, the Eldorado umax and the Bandido umax series are two that also have manual ground balance. Due to the lack of weight and the generally simple operation, the Tesoro's have a fun factor that I feel is missing in some of the other detectors on the market. My two cents.
