18x15" SEF Butterfly Search Coil

Should You Own an EXcelerator Search coil for your Metal Detector?
Search coils supplied with all metal detectors are coils that manufacturers feel give the best all-around results. However, both larger and smaller size search coils are necessary to get the best performance from your metal detector. Experts say "One coil does not do it all " Other sizes will produce additional "finds."

When should you require an Elliptical search coil?

All SEF Butterfly search coils have an unusual blunted shape to the front and back of each coil resulting in greater depth and a wider searching scan letting you cover more ground in less time resulting in more "finds". What does an Excelerator SEF Coil do?    It creates a Symmetrical Electromagnetic Field uniquely combining both DD ( Double D) and Concentric detection signals resulting in your detector getting the best sensitivity of both types plus greater depth!

Field testers have dubbed this new addition the "butterfly coil" due to its unusual shape and they've also reported that it goes deep! The new S.E.F. design is patent protected and has proven to be far superior to many other concentric, "DD" type search coils.

The new S.E.F., or butterfly, EXcelerator coil is designed to offer better, all-around performance when compared to other "DD" coils on the market today. Better ground balancing, more stable operation, more accurate pinpointing and increased target identification are all benefits of this coil.

Field tester Don Echols in Virginia reported finding "35 bullets on a site that produced only 8 in the same amount of time with a different coil." He states: "Several of the bullets were in the 4" to 5" depth range and gave a good sound as well as a good VDI reading" with his White's MXT detector. Don also noted "The novice or rookie hunter may have a difficult time with this coil, but if they stick with it, I'm sure they can add to their collection."

Taking the coil out with his MXT to a different, more common soil location, Don reported: 'The coil was reaching down at least 10" for tiny bullets and easily getting the larger ones at a foot. The shallow targets sound and read good, but the deep items are inconclusive. To dig, or not to dig, is up to the user - I almost always dig and it pays off."
