............in other words everybody else on this forum.This is going to sound weird but stay with me if you can. Over the last 2 yrs I have alternated working tot lots and parks with detectors using elliptical coils and round coils. Often I was using the same models alternating between both types of coils in relatively mild conditions. Here's what I've concluded.................the round coils simply produced better finds ,more often, and a more consistently as well!!! I mentioned this to a fellow who owns a Garrett Scorpion Gold Stinger,,,,,,,,he has both the round and the elliptical coil and he also can't put his finger on it....but prefers the round coils over elliptical as well, I get the feeling that Monte who is a very knowledgeable detectorist might agree.Same goes for my Troy units and the Tesoros.There really is no scientific proof but rather just a "gut feeling", any body else feel the same......or care to comment. Thanks.

Hi Ivan

Are you refering to round coils as concentric and elliptical as DD coils? I've seen and used round coils that are DD and also eliptical shaped coils being mostley DD but there are elliptical shaped coils that are concentric geesh thats confusing.

Then by all means......I like round concentric coils the best, they hunt deeper. The concentric coil covers less area than a DD coil during the sweep of the coil, and if hunting for deep targets you have to move forward with more coil overlaping. The concentric has better discrimination, especially biased against the pesky, rusty, steel crimp type bottlecaps. Pinpointing is also a high point with this style of coil, they are all I ever use now.

I prefer the concentric coils due to more depth, seemingly less chatter and crackle over the iron crud in the soil too when compared to a DD type.

My hunch is that the push for DD coils is because of the smaller shipping box size required for shipping and of course storing in a warehouse.

Have you ever shipped a tesoro detector with a two piece rod? Its not fun. The box has to be HUGE to accommodate the upper S-rod section only. As soon as you bring this into the USPS office they whip out the ruler and smile because its an easy 5 bucks more just for the size of the box.

The three piece rod probably wasnt made for OUR convenience, it was for their own, to save on shipping and shelf space not to mention shipping box size costs too.

Same with say, an imaginary (for example only) 12 inch round concentric vs a 12x6. DD or even concentric. The storing and shipping footprint is smaller.

You multiply this times a few hundred times and you may have some serious money to be saved by pushing one over the other.

Hunting location dictates the style coil that should be used. Heavy mineralization calls for a DD coil for better depth. As far as the shape goes, I always assumed the elliptical coils on a gold detector were for getting into tighter spots a round coil couldn't reach. I could be wrong but it makes sense. Concentric coils have always been my choice of coil for my area. I get better depth and less bottle caps with the concentric coils, plus I prefer the superior pinpointing abilities of the concentric coils.

I use the 5x10 elyptical DD for better sweep coverage. Working modern soccer fields I am not looking for depth beyond 4 inches. But I have noticed that the DD tends to "skip" over objects without barely breaking the silence when swinging too fast.

I use a Tejon with a 5X10 elliptical coil most of the time. When they first came out with the coil on the gold detectors it was to be used very slow. Two feet per second max. Less would better. I use the Tejon at ghost towns, and construction site where there is trash. Your best coil would be 12X10
