Ive had my Tejon for the past couple of years,used it extensively and think Ive seen its strenghts and weaknesses it most applications.My other machine of choice is a Whites MXT and in its own right is a top of the line machine. To me the Tejon is exactly what Tesoro bills it,a relic machine.Most of my hunting is done in Colonial era agricultural fields and in this arena the Tejon shines.I've picked up a silver filling from a tooth at over a foot deep with the Tejon and found English halfpence in excess of 15 inches...To say the Tejon reaches deep is an understatement.When I'm done with a cornfield I can walk away knowing I havent missed very much using the Tejon..The Tejon goes strictly by sound as whether to dig or not and after awhile you learn the language of the machine.Its simple and you arent overloaded with too much information.I do like VDI numbers and such but dont really think I need that level of discrimination in a cornfield generally.If there is a downside to the Tejon(and its not a downside to me)you will dig iron.The Tejon consistently gives me good signals on iron items but quite a few of these iron items I end up holding onto. Things like oxshoes,iron tools,axheads I do keep so its not such a bad thing.For the type of hunting I do most of the time the Tejon is my machine of choice hands down. Its light,tough,hits incredibly small items deep and wont disappoint you if you take the time to learn and appreciate all this machine can do for you in the field....
