Ever wonder how much discrimination is too much? The first of my blogs that Minelab has selected to post to their Treasure Talk should help answer that question. Here is a link to Minelab's Treasure Talk. http://www.minelab.com/treasure-talk?category=17465

From what I understand, Part 2 of this article will be added next week. HH Randy
 
Well written piece Randy! It is great that your expertise is getting out to a large audience. As always, thank you for your work as moderator/coach/VHF psychiatrist!. More than once, your posts have kept the X-70 from wrapping around a tree!

Congrats on being asked to blog on the Minelab site Randy. It is well deserved.:clapping:
As an interesting extention to your comments about using the multi tones and dragging the coil back and listening to how the audio changes (or not on good targets) to a lower tone; I've been noticing that when I use the 5x10 coil on the 70, when I get a reading in screw cap (Aussie $1 and $2 coin) range. A screw cap very often lowers its tone, while a coin usually stays at the same pitch. But you are spot on when it comes to iron targets. Regardless of coil, once the receive coil has gone past the target, it always reveals it's sell to be iron, if that is what it really is. It sure is a useful piece of knowledge.
BTW. That was a remarkable find that you made for that family, in regards to the large cache of coins you found! Even though there no monetary reward, it must have been a sweet moment, not to mention, the good feeling that something that was long lost, was returned to it's rightful owner! I've only had the joy of doing that once. When I found out a bit more of the background of the dad that had lost it and the hardship that their family had gone through prior (unrelated to the wedding ring that was lost) it was an extra special moment. Makes you glad and proud to be a member of the human race.
I look forward to reading other blogs that you write down the track.

glad you got something out of the "dragging the coil" information. And thanks for commenting on the silver cache I found. It truly was an honor to find it for the family. So far, I believe you and Turnmaster are the only two who read far enough to see that part of the introduction!

Thanks again. HH Randy
 
Very good article Randy. I do have a question. You refer to using the multiple tone mode. By this I am guessing the (2:geek: tones? My question is this. I have tried and tried but I can not process more than 3 tones. It may be due to my Tinnitus, or my hearing loss. I am not sure. I pretty much stick with 3 tones. Does the application of less tones negatively affect my finds? Thanks in advance, Beale.
 
I appreciate your kind words. If you get a notion to wrap that thing around a tree, drop me a line and I'll try to help you through it! LOL HH Randy
 
Multiple tone mode is 28 tones. I know the earlier series X-70 referred to it as 99 tones. But since there are 28 notch segments, there can only be 28 different tones. To answer your question, the way that not using more tones could affect your number of finds would be that you have to spend more time looking at the TID instead of covering more ground. Regardless of how many tones you are able to effectively "process", rest assured your detector will beep when the coil passes over a target who's conductive value has been set to accept. It's just a matter of looking at the meter to confirm the target ID.

The reason I prefer multiple tone mode is two-fold..... one is that it allows me to "hunt by ear" and I don't have to look at the display to determine whether or not I want to stop and dig. As I said, each notch segment has it's own separate tone. Matching an audible tone to a display number allows me to keep my eyes on the soil under the coil. If I'm in an area that I want to cherry pick for quarters and dimes, I can do that with multiple tone mode.
two.... when I come across a deeply buried target, it will sometimes give me a "wrap around" high tone and make me think I've hit big silver. When I look at the numbers, they may bounce between +46, +48, -6 and -8. When I get a squeaker of a high tone, the first thing I do is slow down my sweep and go over it again. 75% of the time a slower sweep will lock in the actual TID value. But if it still gives me that little bleep of a high tone, I hover the coil over the target and center it under the coil. Then, while still slightly moving the coil back and forth over the target, I slowly bring the coil toward me. As the target gets near the edge of the coil, deeply buried iron will produce multiple different low tones as it leaves the field of detection. I refer to that combination of tones as harmonics. If I were to be using any of the other tone settings, (one tone, two tone, three tone or four tone) all ferrous targets (negative numbers on the TID) produce the same singular tone, and I wouldn't have those harmonic tones to let me know it is very likely a chunk of iron with mixed ferrous properties. JMHO HH Randy
 
I can't decide wether you are an English major or a Physacist, or a Humanitairian. LOL

After using the Explorer, I think I will give the 99 tones a shot again.
