Tejon and larger iron
- Thread starter Harry_MD
- Start date
With practice when pinpointing the iron just covers a bigger area while a coin does not..Another method is to swing fast over the unit and the iron will sttutter or go away and the coin will not..
Try it as it really works and all units like iron especially a rusty piece that have been in the ground for a long time...

I use a 5X75 conc. coil for my Tejon most of the time in iron. It helps.

I've tried using the field size in AM but it doesn't seem to work 100% of the time. I've dug iron that seemed to show up as less than the coil width. Does that mean I made an error or can that really happen? I'll try the rapid waving, I'd read about it but had forgotten.

Thanks slomotion,
I was actually using the 5 3/4" conc. coil with my Tejon. Oh well, at least I wasn't digging nails.
Harry
Harry sometimes a small nail can fool anyone but time in the field and it will all fall into place as its just that obvious...take one trip to just experiment and dig some large iron while trying to size as it will help you the rest of the season...Coins just cover a small area and after a while it will sink in..Also a coin is a clear-clean signal usually and sometimes large iron or even small iron for that matter will stutter...not 100 percent kind of thing but will sure cut down the odds...Tejon has a language of its own and once your learn to hear TeJon you will dig less junk and more goodies in the pouch....

I've read the tone adjustment can help, especially with a higher tone.
I listen for smooth tones. X the target.. Iron will often break up, blip, or null with X'ing... Lift the coil, swing, and listen... Size should be small..
I dig coin size only.. Once in a while they'll be a sweet sound in the middle of Iron that I can't resist... Some times it pays off.

Practice and listen.
As Dan mentions, sweep speed can help with some targets. The iron sound with the Tejon is one that can be learned with practice and observation. Not a 100 percent identification of iron, but can get much better than when first starting off.
Most iron will give sound differences when compared to non-iron targets in discrimination mode. The edge of the beep (both leading and trailing edges of the beep) will be sharper, more abrupt. That sharp edge on both sides of the beep is more characteristic of smaller iron pieces with the discriminator set in the low iron range. Large iron, even when fairly deep, gives an echoing sound in the middle of the beep; sometimes the echo will extend past the normal trailing edge of a beep. The echoing is different that a non-iron target. A big piece of lead, like a melt spillage or a large sinker can give a bit of a saturation overshoot in the sound, but it doesn't echo or boom like a similar sized piece of iron does.
I needed to go over many many targets to get the sounds mostly worked out. Hopefully you learn faster than I do!

Some great tips folks, many thanks.
As important, you've given me some hope that I'll get better at this. Right now a flat button, a musket ball, a piece of kettle scrap and big iron with a good halo all sound the same to me. I keep searching for differences in tone and ramping or middle tones but they're just not there for me.
Next step, a test garden.
Thanks again,
Harry

Harry,
Headphones help with hearing the subtleties an awful lot. They also don't attract as many curious kids and some adults who hear the speaker beep and are drawn in. Batteries last a little longer with headsets. Yes they do make it more difficult to hear what is gong on around you. I don't hunt without headphones unless I'm showing someone something about a detector or a target.
I like the Koss QZ99 headphones. I keep two pairs of that model on hand just in case one dies. They shut out the outside noise very well so they may not be a good choice for you if you want to hear what is going on around you. Ask for some other suggestions that get good audio response and still let you hear some of what is gong on around you. I'm sure this group will have some suggestions.
Cheers,
tvr

Rattlers - one ear cup
Or just use cheap over the ear phones...radioshack sells a decent set for $10 with inle volume control... You'll need an adapter.. I prefer the light weight cheap ones... I can still hear my surroundings and get better audio info

Yes a good set of head phones is a must. I have a pair of Grey Ghost. My dad has a pair of Black Widows which does have a different sound than the ones I have. They are hot a sweaty in the summer and nice and warm in the winter. When working out trashy spots and deep signals. It really helps hearing the sound your looking for. When hunting in the big city. I always keep the head up looking around for dogs or people. I try to hunt with a partner.
The subject of headphones brings up another issue...cheap or expensive. I've read posts that say cheap work as well as expensive while other posts insist that cheap headphones are worse than none. My experience with a cheaper model of White's headphones is they do little more than keep my ears warm on cold days. That may just be my lack of experience.
I'd welcome any knowledgeable feedback on this subject. If it warrents it, perhaps it might be best to open a new thread.
I've tried some of the tips on IDing iron and I've gotten better. Analyzing tones still leaves me in the dark but rapid coil movements have produced some encouraging results. The really odd thing is difference in results at two sites. At one site the Tejon discriminates out iron about 95% of the time while at another it gets fooled about 95% of the time. Any ideas at what might be at work here?
Thanks,
Harry

Harry lots of good headphones out there from inexpensive to expensive but a good rule of thumb buy a pair to your liking and stick with the phones and don't keep changing phones as your question does have merit.
Personally the pair I am using are inexpensive Calrads made for metal detectors and still going strong after 8-9 years and do have a brand new backup pair in the trunk..Used many expensive
detectors over the years and they served me well but again many swear by the X or Y model so your call...

Harry,
Agree with Dan on headphones. I tried several until I found an affordable model that I like.
As to iron discrimination at the two different sites, did you happen to look at the dirt dug from around the recovered iron? I've had some locations where the target just disappeared when I dug. The digger and the hole would have big red rust streaks that the detector hit hard until I dug, then did not hit at all once the rust clump was broken up. Smaller iron discriminates out better than big and if the big iron is nearly disintegrated in the ground it can still fool me and I'll dig a shovel full of nothing but ugly red rust. Could be that the iron from the target at one of the sites is leaching in to the soil more than the other. Could be that the general soil characteristics are more mineralized at one site and the detector ground balance setting is more critical. May have to spend more time adjusting and observing the two sites and targets dug to draw better conclusions. That's part of the fascination for me.

Thanks again folks, obviously I'm going to have to try those headphones again.
Oh yes, many of the objects disappear or are clearly IDed as iron by the detector once out of the ground. One explanation may be the "bad" site has more iron with halos while the iron in the other site is right beside my house and has been moved around a lot over the years, hence fewer halos. Yes, I should have removed every iron piece found.:blush: Another very experienced friend suggested the difference may have come about about because the "bad" site holds a lot more moisture. This could make sense too.
