    Re: question.

    a Mono Coil sends a round Signal in the ground
    like a Funnel Name: imagesws.jpg Views: 98 Size: 2.7 KB
    the deeper the Signal the Smaller coverage area

    a DD Coil sends a narrow signal
    stright down from front to back
    Name: images.jpg Views: 98 Size: 3.1 KB
    like a paint brush

    So when you get 8 to 10" down

    how much Ground do you wanna Cover ?

    The Mono will get a little better Depth
    but is it worth it
    when you have to be
    that tight on your Swings.
    discriminate out Spike TV and American Diggers !
