I must confess that is not my MD. I saw it while inspecting a house in Alabama for Hurricane Katrina damages (I work as a FEMA Housing Inspector after disasters). I told the applicant that I HAD to have a pic of me with that HUGE coil (biggest I have seen). It was 24" in diameter if not larger. I'm not sure how good it is for depth but it would halve the time it takes to cruise through a park looking for surface treasures.
Yep. It was real. The guy that owned the MD did not know how to use it at all. I happen to own the same MD (White's XLT) so I offered to give him a quick lesson but his batteries died seconds into the lesson. I really wanted to see how that mammoth coil would perform.
Notice that coil has braces to support the additional weight cantilevered out there. I would expect your arm would get tired pretty quick swinging that thing around.
One thing I really like about that coil is if it rains you can just get under it to stay dry.
I have a coil something like that but I use it as a kitchen table you can put the trash
can right under the hole in the center it works great.
Magnum Force Loops are designed by Jim Karbowski for use by Cache and Relic Hunters. Both the 15" and 25" loops are maximized for high sensitivity for larger, deeper targets and are extremely lightweight for their size. Both loops are designed for use on all White's Pro's, Eagle's, Quantums and Spectrums.
The 15" Magnum Force loop is best suited for finding targets in coffee can size or larger and will achieve depths up to 3 to 5 feet depending on the detector used and the size of the target. This loop is a favorite among Relic Hunters.
The Magnum Force 25" loop is the "Big Daddy" of the deep searching loops and is designed for the serious Treasure Hunter. Relic and Cache Hunters can achieve depths of 6 to 9 feet, again depending upon the detector used and the size of the target. Although the 15" Magnum Force Loop may be used in the discriminate mode, such as when relic hunting, large loops perform best in the "all metal" mode and achieve their best depths when searching for larger targets. The 25" loop should only be used in the "all metal" mode following the instructions enclosed with it. For ease of operation, a Sierra Arm Support System is included with the 25" loop.
