Went Ground Sweeping Today

[nad]

With the weather still mild, I decided to go back to the playground. Yesterday,the ground was frozen under the chips, today mud and wet..Figured the other guys would be around.As I walked around the building ,they were driving off. I wanted to get a time estimate for the 3 by 18 Ground Sweep coil compared to the standard "V" coil.....Normally the area would take a bit under two hours,to cover. Left the house at 11;30 ,got back at12;25..Walking time each way seven minutes..Found eighty seven cents,and a small kid's pendant..Deepest item was a nickel at a measured seven plus inches.Smallest item in the quarter inch range..I have been using the wide scan coil in various areas before, but in no place where I could get comparative times...The coil was used as a big X to pinpoint, then use the end of the coil to get in closer..A pin pointer will be needed out on the soccer fields...I knew the wide scan coil covered ground faster, but not that much faster. A very pleasant surprise....Ground balancing is very easy to do with the 3 by 18 coil....Sensitivity was not really jacked all the way due to electrical interference..I didn't have the machine set up for the coil, so it was slightly awkward and needs to be adjusted..For all day hunting ,I may consider a sling.....Working in and among the iron supports is not any different from using the standard coil, cordially Nad

Nad,
When you say working in and among the iron supports is not any different, does that mean you can get as close but not closer to the posts with the 3 x 18 as compared to the standard 9 x 8?

Glad you could get out!

I just purchased the widescan 3X18 for myself for Christmas. Took it out today for the first time. I have it mounted to a Cibola. My first impressions is this: You may need to adjust your rod out one notch - I found this to work better, as the rear of the coil is too close to my feet. Of course, this makes it weight a little more - kind of hard on my right shoulder. I still managed to swing for 5 hours with it! Man - can you cover a lot of ground with this thing! I hit the soccer fields that I have hunted off and on over the summer. I came out of there with $5.07 in clad and a coaches whistle. This coil is kind of a sleeper - not well known to detectorists who own Tesoros. If you own a Tesoro - this would definately be a coil to own - next to the 5.75 incher. Keep in mind, it is not the best coil for trashy areas, but, in soccer fields and the like that are less trashy - this coil really shines. I easily covered twice the amount of ground today in the same amount of ground, and coil overlap is not a concern with this 18 inch monster. If it is in the ground, then this coil will likely find it.

I still have a few hundred acres of gound that I can think of where this coil will excel compared to standard coils. This coil will definately help you in more finds. Tesoro has a winner with this coil.

TVR,, posts.About the same distance..However, changed my search pattern.With the standard coil, I would work into and through the Jungle stuff,trying to keep even slices of the yard. With the wide coil,I come close, go around, then come back later. Seems to work much faster...With this coil,I find that I am swinging once as opposed to three times to maintain over lap..I also, had the long side towards me..The coil cover is loose, so that added to the stress.Keep on meaning to do something about it...I have to check out some of the small gold found with other detectors and coils, and see if there are any problems..Ground is firming up, windy, and temps dropping, so this was the last train for the year...

Some target distances..I have several 1 inch thick boxes filled with dirt....I ground balanced the "V"( with the 3 by 18 inch coil), and put the first target on the ground, and covered with a box, and so on , until no more signal First target a 14K earring stud,1/2 inch long,1/16 diameter. Clocked in at one inch, not at second inch....Singapore gold Tiger 1/20th of an ounce..In at four inches,just made it at five..Small gold plated ring 3/4 inches in diameter. there at 5 inches..14K diamond ring 7/8 inch diameter nominal,.a good seven inches.(no more boxes) On that last ring, no wonder I found it, the darn thing must radiate signals.The small gold coin was about 9/16 inch, a dime is 11/16...My concern was that small gold rings would not show up .Sensitivity was maxed, I used discrimination below nickel and above small iron nails..Speaker sound only.This is just as I would hunt in the fields..Cordially Nad
