Why Should You Purchase an EXcelerator Search Coil for Your Metal Detector?
Excelerator Search Coils are Made to go Deeper Than Factory Coils!!
The search coil that comes standard with most metal detectors are ones that manufacturers feel give the best all-around results. However, both larger and smaller sized search coils are neccessary to get the best performance from your metal detector, not to mention making sure you leave no treasure unfound! EXcelerator search coils are world-renowned for their depth and manuverability. Small, medium or large, any EXcelerator coil you add to your metal detecting arsenal is almost guaranteed to show you treasures at unheard of depths or in places you never thought you could detect!

- Accurate pinpointing
- Easy to handle
- ID targets "right-on!"

When Will You Require a Larger Search Coil?
It's happened to us all at least once: You're detecting and finding lots of good targets like U.S. Civil War bullets or wheat pennies from the turn of the century. After a while the amount of hits becomes less frequent and the audio signals from your detector become weak; letting you know that your search coil has reached its maximum detection limits. But you KNOW there are still deeper, more valuable targets in the ground. With an EXcelerator search coil you don't have to leave those valuable, deeply buried targets to be found by someone else!
Kellyco's 14" EXcelerator search coil's maximum detection limits can be as deep as 15 or 20"! One of our more powerful EXcelerator search coil is the 18", which can penetrate to depths of 20 or 26" and locate a single coin! It can go even deeper than 26" for caches and other small or large treasures that other detectors and average search coils simply cannot reach!
By using larger EXcelerator search coils, such as the round 12.5", 14" or 18", you will be able to detect deeper; find older targets; and even search a wider area in less time! To go even deeper to find the more valuable old coins, relics and other treasure including gold nuggets, use EXcelerator S.E.F Butterfly 15x12", 18x15" and 21x17" coils.
When Will You Require a Smaller Search Coil?
By using smaller EXcelerator coils, such as the 5"DD, 6"DD and 8"DD, you will be able to search for older, more valuable coins in "hunted out" areas. Smaller EXcelerator search coils are extremely selective in heavily trashed areas where its size can see coins below trash; even when surrounded and covered up by junk items!
Kellyco's 5" EXcelerator search coil is perfect for finding thin necklaces and bracelets that are virtually impossible for other detectors and larger coils to locate - jewelry is where the smaller EXcelerator coils prove their value. Whether gold or silver, rings are no match for these dynamic, DD search coils! Most users realize that one valuable ring find will easily pay for their entire metal detector purchase.
Regardless of your metal detecting preference - coins, rings, jewelry, relics, artifacts, caches, small and large treasures as well as gold nuggets - all can be found with detectors using EXcelerator search coils!
