Question

Question: On the 705, can all high conductive coins be discriminated out. In other words can the 705

be adjusted where only the nickel coins are heard?....When I hunt mainly for gold rings I don't want any coins other than the nickel be heard......Jack

you will be excluding many other gold rings...both big and small.

I think you would be making a big mistake.

In our soil just about every ring that any one of us has found ID'd much higher than a nickel. I found a monster of a men's wedding band earlier this year that was a 32. Many of the others have been in the 38-44 range. I'd think twice or even three times about notching stuff out. With rings, you have to take the bad with the good to be successful.

A lot of people say that they get rings down in the 6 or 8 range. You can't prove that by any of us because not one of us in our family have pulled up a ring that low in nearly 4 years of using a 705 so I guess it really depends on the soil or the makeup of the ring. My brother an I always joke with each other when digging a 6. We always say "let me dig this ring and then we say.....huh, it's junk". I'm not doubting that people get rings as 6's but one day I scanned about 25 rings that either belonged to people that we knew or were previous finds with older detectors and not one of them was a 6 or even 8.

Have fun!

Starting off, notching out can be a detriment. It's much better to know your conditions first, what may possibly be in the ground in the areas that will be hunted, and what some of the pesky targets ID as, prior to bringing in the notching aspect.

Last thing...don't under estimate the exact opposite. The 705 in all metal mode provides tonal variances on targets that may actually HELP more than the ID. Great thing about the AM button ! Get an iffy target in discriminate, press that AM button and listen.

I can show several gold rings that TID 4,6,8,10.............but I'll leave it to this one! Solid 6TID 18k

Some very good advice here,, but to give you a direct answer to your question. YES you can notch out everything except where a nickel reading might fall.

I love it when someone answers a question instead of giving a bunch of reasons why you should not do something. Most of the time is because the replies don't really know the answer.

Well done.

Relating our experiences is what this forum is all about, so sharing reasons why it might not be a solid approach is prudent.
Yowow is correct, the 705 has 28 target segments that can be individually manipulated, and four custom programs can be saved as desired.

As for where gold comes in....I've found it anywhere from 6 to 40. Mass has a lot to do with TID!

Not unlike bob.oz, this 14k was a solid 6.

Thanks for all the comeback. Maybe I did not make myself understood. Number one when possible I dig everything but high conductive coins I think while I am digging clad coins, I can spend that time looking for gold rings. I want every target I dig to be a potential gold ring..If the area is completely littered with pull tabs I go to the discrimination pattern I mentioned.I do not have the back or time to dig every pull tab, After all who wears the most rings. Women. They are mostly very small and light. some have stones. I think of all the rings lost, I think about 60% are in the nickel, foil range. Been detecting 38 years. I have found 116 gold rings using this type of discrimination. Maybe I will miss a silver ring or silver coin. What are they worth compared to gold. A silver ring maybe 1.00. just my style. I have 4 detectors that I can eliminate coins I have come across a 705. A pretty good price, but I was wondering about the discrimination. Thanks a lot for the comeback.....Jack

That's great that you guys have found those on the lower TID's. Luckily I can say that I doubt we've ever missed anything like that because we dig those TID's, they just come up at a higher TID for us. It's just a pain that we've dug so many lows and not turned up anything in that range. We might not have anything with a stone as big as Bob's but I would say definitely similar bands to what you guys have found. As long as we're finding them, that's the important part.

This is definitely one hobby that in a few short years or even in one find you can easily recover well over the price of your equipment.

This is definitely one hobby that in a few short years or even in one find you can easily recover well over the price of your equipment.

One reason that I like the hobby, is that beyond the price of admission there is little associated cost. My biggest annual expense is fuel, but with every other endeavor you need to spend for fuel anyway, and then you add the cost of whatever the activity is on top of it.

Back on topic......around here if you want to enjoy any frequent success finding jewelry you need to get into the water. The ratio of jewelry to clad & junk is more in your favor in the water.

The discrimination scale of the 705 is broken down into 28 "notch segments". Four of those notch segments (those with a negative number) represent ferrous targets and the 24 with a positive number represent the non-ferrous targets. (non-ferrous = a formulation of inductive properties and conductive properties). You can set any of the notch segments to be either accepted or rejected. Actually, the 705 will detect all targets, regardless of whether it is set to be accepted or rejected. Rejecting them merely shuts off the audio for that notch segment. So in essence, you can set your 705 so that it only provides and audio response on the notch segments you want. If you set it so that the only notch segment that is accepted is the notch segment representing nickels (typically TID 12), then you will only get an audio response from those targets whose properties register a TID of 12. Everything else will still provide a visual response on the screen. You just won't get an audible target response, other than nulling of the Threshold.

IMO....the TID of gold rings will vary, (in part) based on size, shape, purity (K), alloy incorporated and whether the band is intact or broken. Depth of the target, angle of the target and soil matrix can also play a role in the stability of the TID. JMHO HH Randy

Hey Randy: Thanks for the information.....Jack

I agree that sharing experiences and thoughts are prudent but so many times I see questions ask (some that I would like to know the answer to) that never get answered.
Happens all the time.
