Does anybody have any info on the HotFoot Coils? If so, what advantages does this have over the 4x6 or 6x9? I have been using the 4x6 over the stock 950 coil and have been finding alot more items with the smaller coil. Easier to pinpoint too. The only thing that I am worried about is that I am not covering alot of ground with the smaller coil and thought the HotFoot might be a nice comprimise. I am relatively new with the MXT and any help would be appreciated. Thanks.
