While on the subject of the 18.75 Elliptical

[NH Bob]

Just so happens I came here to pose a question to the users of the elliptical coil.
I'm not comparing machines but using the two as a reference. I own a Shadow X5 with a 5 X 10 DD coil. I also just purchased a 5 X 10 DD for my 70.
The shadow is a very deep and sensitive machine and runs at 19 kHz
The new coil for my XT70 is an 18.75 kHz. Seeing both are high frequency machines, do any of you that use the 5 X 10 DD on your XT feel it has good depth on coins? (silver and copper) I know the HF coil is good for gold and small items. But is it any good for coin and relic hunting? Getting old and the coil is nice and light.
Thank you in advance
NH Bob

Packed gravel, not the greatest soil for depth. The HF DD used was the 5 x 10.

Thanx Bill.

Hey Bob----Just two days ago my wife dug a copper penny at an honest 8 inches with that coil on her 705.--Granted, the soil was moist but I thought that was very good depth for that 5X10 coil.-----Del

That's good with a coin signal. Digging the iffies should get you anothr couple inches in good soil.

What i find strange that the American detectorists do not do when they go into detail about their finds is that few few give us thier settings as well. Its little use giving us a small story if we do not know the settings guys are using ,so, we can either avoid or employ them depening on the story .
Barnacle bill tells us a great little story but told us he GB and his sens was 16. Not all his settings were told. Why not ?

 

[NH Bob]

One reason might be that the GB & Sens. are about all that are the main settings on the X-Terras.
Vol, NC, #Tones and Threshold vol. are usually things you have set when you start out at your site.

Thankyou Bob.

To All You X-Terra 70 Fans,

Compared to you all, I'm a green horn with my X-Terra 70 but I think I found the magic recipe to finding silver coins. Obviously we begin with the X-Terra 70. Add one 18.75DD 5" x 10" coil, set your program to Patterns #2, set noise cancel, ground balance, and hunt! This morning, in a little more than two hours, I found seven quarters, three nickles, two dimes, one Canadian penny, a hunk of silver soder as big as a pinpong ball, a bar of aluminum, and a Susan B. Anthony Silver Dollar. Of course several pull tabs and other junk was thrown into the mix. Last week I found a Sacajawea Dollar but this is my first 'Susan'. If you haven't tried this combination on your X-Terra 70 ~ give it a try. What have you got to loose? My average finds were 6"+ with the deepest being 8"+ and the shallow being less than 2".

Unfortunately none of the quarters were silver but, in three day hunting 2-3 hours each day, I have found $9.50 in quarters, $2.00 in dimes & nickles, a handfull of pennies, and one 'Sunan' silver dollar. I thought that was good for the six+ hours invested. Oh ... did I mention ... that the first day I used the 'standard' 7.5khz 9" coil w/Pattern #1 and couldn't find a thing? Changing coils to the 18.75DD 5" x 10" and using Patterns #2 made all the difference. So the majority of the coins were taken the second and third 2 hour days. The 18.75DD 5" x 10" coil & Patterns #2 made a belieaver out of me and proved to be a great combination.

Believe me I tried using the 9" 7khz standard coil in Patterns #1 but there were so many signals that the standard coil couldn't separate the targets. I also tried the same setup in AM but too many sounds. When I put the 18.75DD 5" x 10" coil on and chose Patterns #2, everything settled down and target separation was incredible. I wasn't hunting for gold ~ only silver so Patterns #2 worked well for me. Patterns #2 finds all silver coins, as well as clad and it's great on nickles. It would be hard to argue with the results. If you've got the 18.75DD 5" x 10" coil, give it a try. You may just be very surprised.

No doubt the type of ground and or site your hunting in would make a difference in which of the 3 Patterns you choose, if in fact you chose to hunt in a Patterns Mode at all. When I wrote the above mentioned article, my sole interest was in finding silver and clad coins and eliminate all the extraneous noises I had gotten in Patterns #1 and in AM Mode, so Pattern #2 was a good choice. If I were detecting at the beach, for instance, I probably wouldn't use Patterns #2. I may hunt in AM or Patterns #1. There have been a few times when I chose to detect in the Prospector Mode and dig everything! By choosing Patterns #2, I don't think I missed anything deeper. Occasionally I had gotten signals, on quarters, that turned out to be 8" - 10"! How deep do you want to dig? And I noticed too that I dug many different types of metals in Patterns #2 but the majority of the signals were silver, clad coins, and aluminum. I really like the 18.75DD 5" x 10" coil and, by using it, I won't be missing any gold providing, of course, I'm hunting in AM, Prospecting Mode, or Patterns #1. Does that answer your question Turnmaster?

I nthink your targets were close together nd that's why your stock coil was not separating signals.
The DD eliptical is much better in that situation than a concentric coil.
I am Air testing a foot on Large coppers even though I haven't dug one that deep with this coil yet.
I have been using it since I posted this topic and am learning to like it.Now, if they would only make the eliptical in the other frequincies, that would be awesome.
I hunt old sites only. No schools or parks.
