I didnt find it performing any slower. There were times it was more susceptible to EMI from power lines. The area Ive been pounding by the swim center will be a good test for the MF setting to see if it can hit anything the 15Khz setting missed. At some point I will venture back to MF in some of the fields also. So many frequency settings and so little time to thoroughly explore and test them. Im anxious for that SuperFly coil to arrive so I can play around with it. Its intended purpose will be the beach but using it in the open areas while running in MF just might make it shine.
