That is a good idea, a big coil for explorer. I think 40"x20" coil would be an very usefull depth detector... or scanner for car or boat. I could not find such a commercial product, but it may be that there are S.E.F coil 21" size. Someone has already made such a big coil for explorer?
I am interested any info about it! Thanks!
