Hidy D . I have a Tejon . I used it to hunt 55 acreas that the D . P . A . bought to build a Museum on . They wrote up the papers for me to try and find Civil War relics on the land it was to be built on . I used the Tejon about 99% of the time while hunting . From my research of Union City , Tn. I knew it had to be something there . In hunting with the Tejon I learned a little trick for more depth . I used a 12 coil . You can hunt in all metal mode BUT I have used it enough to get more depth with the pinpoint trigger pulled back . While hunting like that if you get a slight signal with your discrimnation on 4 or 5 you can take your foot and scrape the ground off smooth , then let off the trigger , if you still get a slight signal , DIG. I have a post on here on what I found by using that method . I know it sounds unreal but it works . It was 99 out that day and I got so disgusted when I found out what it was I for got to take a picture of it . The main reason I had to dig it was I had just found a standing liberty quarter about 20 ft. from it . And the signal kept coming in on full descrimination . When I pulled the bottle out the signal was gone . The Tejon is ideal for weight and extremily sensitive on old square nails because of the content there made of , and small pieces of aluminum . After that I purchased a V3 & the V3i . I have got the super 12 coil on the V3 for Civil War fields . It does give me more depth than the 10 DD . But the old Tejon is still here for my Grandson to use . It will do the job . I have used many other machines . I only use the Whites now , saves me a lot of unnessary digging . Good luck .
