    Experiences with different coils for Fisher Gold Bug 2?

    To those of you who own one, what have been your experiences with bigger coils? Mine has a 6.5" coil and so far all I've found are small pickers and flakes that were on bedrock areas only. Have you had better luck with bigger coils in deeper ground?

    you will have to be in very easy ground to hit a .5 grain piece at 1.5 inches.

    5 grains is around a third of a gram.

    I own a GB 2 with the shooter and the 10" coil.

    the depth given while "possible" are very "hopeful"

    Once you start getting over a half gram the depth picks up. But, for the tiny sizes mentioned you would need to be rubbing the coil on some very quiet ground.

    Even then without experience and good headphones you will be hard pressed to hear the whisper such targets give.

    I love that original made fisher 6.5 coil, new company not quite as much. Them tiny specks sure add up and getting into tight spots has produced many nice nice nuggets my larger coils can't see or get into tight places-John

    In my family we have three GB2 detectors. We all run the 6.5" coil.
    We have a larger parcel of land to detect. We have all hit it pretty hard with the GB2"s
    3/4 oz down to 1 grain size gold. Finds have started becoming sparse.

    I bought a Makro Goldracer and own almost every coil they make.
    I really thought the 15.5" x 13" coil was going to deliver a couple deep larger nuggets that the GB's missed..so far just 3-5 grain size pieces. I do like it for exploring and searching float gold because it covers a lot of ground.

    If I wanted to really get the last of the surface gold, a PI would probably be what I would buy.

    The percentage of large nuggets to small bits is very low, but it depends on where you are searching.

    The 10" Gold Bug 2 coil (compared to the 6.5") seems to be more sensitive to mineralization issues and less sensitive to the plentiful small gold. It does not seem to give any depth advantage on the smaller gold.

    I owned a GB2 for about 6 yrs, was very successful on tiny gold with it, from one grain nuggets to 5.3 grains was it, using the 3x6.5" coil, tried the 5x10 for zero, and large 7" coil for zero. The 3x6.5" was a consistent tiny gold getter for me. Vlfs are only surface machines anyway for tiny gold to maybe 4" max, if your concerned with half grammers to 2 grammers at depth, get a Good pi with good flatwire tech coils.

    MXT SNIPER - excuse a please I'm a no know what you mean by "good flatware tech coils"?

    Does that mean the wire used to make the coils is flat versus round?? Which would likely mean that the windings have the wires with the narrow edge in an up and down direction with the flat laid so they stack from the coil center outward??

    Also, what brand of coil would that be or "they be"?

    Thank you for the input, "curious George" - 63bkpkr
