Why has Tesoro gone from the lower (10 Khz) detectors to higher frequency ones that are about 14-17 Khz? Seems like the more they have moved up the frequency the more noiser they've become, based on discussions I've heard. Also, when is Tesoro going to come out with a 12x10 concentric for the Tejon? They have them for the uMax series and a couple people have commented on how they help with depth.

Freq of Old vs New Tesoros

and that because it is so sensitive. Look at any of the really deep, sensitive machines, and you will usually see or hear a noisy or chattery machine. When you push the gain on a machine to get max depth, it can make the machine a bit unstable but if you want maximum depth thats the trade off. The V and C are not noisy at all, run nice and quiet just like all the other Tesoro machines.
When the Tejon was being developed, Tesoro tried several big concentric coil designs but because of the sensitivity of the machine they were unable to make one that was stable with the machine. The Double D 12 x 10 was then developed. According to the Giffords, they were unable to make a big concentric coil that worked well on the Tejon. I was involved in the initial design and testing of the machine so I was in on a lot of the problems that occurred during the year long design and testing process. We were sent numerous machines, tweaked and changed as the design process evolved. One prototype was a bit noisy but very deep, so we asked Tesoro to see if they could quiet it down a bit, and smooth out the threshold. When we got the next prototypes they were quiet with a nice smooth threshold but not as deep. We told James Gifford we wanted a machine with the smooth threshold but the maximum depth and were told you could not have both. If we wanted the maximum depth we would have to put up with edginess, it was one or other other. It was unanimous, we both said go with the maximum depth. The Tejon could be toned down, and run quieter and smoother, but then you would basically have a Vaquero, which Tesoro released about a year after the Tejon came out.

and that is, I believe, why all the latest offerings from manufactures are "noisy". The selling point today is depth. And to achieve depth the gain is pushed to the limit of stability. Sad that they, the manufactures, can't improve on target recognition instead. But we have what we have because we, the users, buy the machines which promise more depth.
The V and the C were introduced the same day, and I was at the GPAA gold show in Onalaska, WI, the day they were introduced to the public. I beleive it was October of 2004. Both are built on the same "electronic" platform as the Tejon. The V is a stripped down version of the Tejon, with the gain pulled down to make it smooth, quiet and more stable, but also not as deep as the Tejon. I like to call the Tejon a "Vaquero on steroids". The C is copy of the V but has a factory preset Ground Balance (turn on and go), where as the V has a manual Ground Balance so you will have an advantage with the V over C if your ground conditions are less than ideal and/or if you prefer to have a good selection of different coil options. They are all basically the same machine, but some have more options and in the case of the Tejon, more depth.
This is why, I think, a lot first time Tejon users, decide right off the bat that they dont like the machine, and then turn around and sell it right away. I wonder how a person can just write a machine off that fast, without really giving it a try. Yes the Tejon is a bit fussy and a bit noisy if properly set, but if you give it a chance you will not be disappointed. If you want a deep, sensitive machine, I dont care what brand it is, it will be edgy, a bit noisy, but thats a sign it is a good machine. I hunted with many earlier Tesoro machines and loved they way they were whisper quiet. If you did hear a "tic" or "pop" it was probably because your coil nearly "missed" a better or deeper target. But now I go back over those sites with the Tejon and I am stunned at the number targets I was missing! I had a Fisher 1260 for a while, and it was a deep machine, but compared to the Tesoro machines it was very noisy, loved iron, and was heavy. I sold it at the end of the summer. When the Tejon came out, it took a bit to get used to the "chatter" after hunting with the classic quiet machines, but knowing it was a deep machine I kept at it and came to love hearing those little noises. Now for me its important to hear those occasional noises while I am hunting because I then know my machine is set to maximum sensitivity and that none of my knobs have been bumped. If I go a few minutes with out any background noise I get worried and recheck my settings to be sure nothing got change. I will rest the threshold and re-balance the machine and continue. If I can hear her talking to me, I know she is happy, and when she is happy she is joy to hunt with.
I tell my customers, no matter what machine they get, to give it at least 6 months of time before they make a decision as to keep it or sell it. You really have to learn a machine and that takes time. And a machine like the Tejon I think its a year before you really know everything its telling you. You cant possibly encounter all of the various scenarios and hunting conditions in a couple of weeks time, it just wont happen. Its a pr oven machine, give it some time, you wont be sorry.

I certainly wouldnt want to have to drag one of those things around to find the few coins I usually find!
