Do you like hunting in all metal but find it a bit too noisy when hunting heavy iron?

All those iron grunts getting to ya making life miserable at those old iron infested spots and at the same time are you worried about all the iron masking good targets? Well then give this method a try.

Set up your detector in pattern 1 with an open screen and watch the TID to see which iron segment is the most active causing all those annoying low iron grunts, then notch that segment out. This should eliminate well over 50% of the iron grunts and if used in the following manner also help determine a good sensitivity setting as well.

Now with the threshold set just to the proper audible level pay attention to the amount of nulling going on from the notched out iron and adjust the sensitivity lower to where you eliminate a good portion of the deeper iron causing the nulling. You will need to keep up with the sensitivity setting, varying it up or down as neccessary while slowly hunting the area. The X70 control interface makes adjusting the sensitivity on the fly easy to do.

I enjoyed using this method for a couple reasons. First its easier on the ears to hunt heavy iron with the biggest share of the iron signals knocked out and secondly it makes me feel like I am being more pro-active in helping the detector "see" good targets in heavy iron.

While I do agree with the guys who feel "all metal all the time" is the way to go as it alerts you to the need to adjust your sweep speed, hearing the nulls alerts me to the fact that I need to reduce the sensitivity which is very beneficial for iron hunting as well.

Some day I would like to see the manufacturers come out with an auto setting based on this method for hunting heavy iron.

I run all metal and just reduce the sensitivity down to just eliminate some of the deeper and smaller iron signal instead of using the discrimination.. Works well..

I do the same as Cosmic but, why not try something different. The nice thing about this, with our X-70 we can do it if we wish.
 
I hunt all metal all the time, I like to hear the iron and high tones mixed in. When I am an iron infested site I just slow way down and pick out the high tones
 
lots of shallow iron of all sizes and types from nails to rusty flat pieces requiring sensitivity settings in the down in the 15-19 range on the X70. :sad: If you can hunt in all metal with sens above 21 successfully your not in the type of site I'm referring too! :biggrin:

Sorry, should have stated that in my original post!

Tom:

Yes I have a problem in farm country with iron in all metal. Makes it almost impossible to use the xterra70.
 
For sure there are better machines for hunting plowed fields especially in areas where old houses once stood. Freshly plowed ground plus heavy iron is hard for a lot of machines to handle!

Experiment with the GB in heavy iron to see what works best at your sites. Compare auto or manual GB to tracking GB and also the factory preset GB of 27 to see which method gives the best response over some found undug targets in those iron trashy spots.

Thanks for the info Tom. I'd like to add that, although using the 3 kHz coil is not an absolute solution for recognizing iron targets, it certainly provides an audio "advantage" over the mid and higher freq selections. (you thought I'd say it gave an "edge", didn't you?) :rofl: HH Randy
 
:surrender: :lol: :lol:

Digger I liked that 3 Khz coil for tough iron hunting! With the sensitivity set in the teens the edge effect is lessened and used with lots of overlap it does pretty darn good for such a big coil. Still you can't beat the smaller coils for those iron challenged sites.

Now that I have the broken wires in the connectors on my coils repaired the Advantage is once again ready to rumble! Chest mounting is tough on those connectors!! ;)

Tom
 
The 3KHz is my favorite coil!! Great in iron fields and old burn pits.. Way deep on on silver and copper that the stock and the 5x10 wouldn't give a good response on in my soil....That's what I like about the XTerra70, great versatility!!!
 
When I was hipmounting my Advantage, I also encountered a problem with broken contact in the coil connector. I improvised a strain relief clamp "set up" that put an end to my broken contact problems. Simply a split ring, a key clip and some electrical tape. I'll post a couple pics of it here. If you have any questions, don't hesitate to ask.

By the way, I've been whining to Minelab for over 2 years for a small 3kHz coil. Preferable DD. So far, no luck. In my opinion, they could have marketed the X-Terra series better. Keep the X-30 as it is, with the 7.5 kHz coils. Make the X-50 capable of 3 kHz and 7.5 kHz. And the X-70 would stay with all three frequencies. Allowing the X-50 to operate at the low and mid freqs would have resulted in LOTS more X-50 sales. Not to mention 3 kHz coil demand. The way it was released, only the X-70 can use the 3 kHz. With Prospecting mode and Beach tracking, the higher freq (and mid freq) seem to get most of the attention. :shrug: Oh well!

HH Randy
 
Digger I should have used some kind of strain relief long ago. Thanks for the pics they are very self explanatory!

Regarding the X50, I agree the low frequency would have been a better pick for the optional coil.

Tom, what do you mean? "For sure there are better machines for hunting plowed fields...", than the X-70? What machine is better for this condition than the X-70 with the 9" 3kHz Concentric or 10.5" 7.5 kHz DD in your opinion? The MXT with large a SEF, F75 with a SEF, Vaquero with 10x12" DD, or the 5 kHz Musky Advantage with a 15" DD WOT or 12.5" or 14" DD EXcelerator?? Or did you make a mistake, hehe.

Definitely not the BBS and FBS machines for sure as they are not good in black dirt plowed fields and painfully slow coverage speed to cover the most amount of ground in a day in large farmers fields. So what unit is the best then if not the X-70?

I agree with the wrong frequency pick for the X-50 Randy. We also need a 6" 3kHz DD and a round 10.5" 3kHz DD very badly. (We can do without the 9" HF Con. and the 6" MF Con. IMHO.) What was Minelab thinking, doing things wrong in these particular situations?

Great idea for the Musky hipmount strain relief! I have a black box Musky Advantage and do not have a hipmount bag yet but I want one.
