The 3 khz 9"coil made a difference for me!

[Jack Flynn]

The 3 khz 9" coil I aquired "used" here does make a difference! I hunted a 40X40 foot piece of dirt around of all things a sealed top "wishing well" at an over a century old park last week meticulously. I gridded it very well with the 7 khz CC coil and then raked it with an 18.75 DD coil. I targeted some 25 pennies and a dime and a nickel. All this was in the planning for hitting it with the 3 khz 9" coil when it arrived. There is a lot of iron here and a bunch of non repeatable signals in the dirt, "pull tabs" evidently. Today I got one hour in that little 1600 sq ft area. About 3 swings into it I popped a quarter out right at 8"s. Then five pennies in a row 4 to 6"s. I hadn't done a 6X6 spot for these 6 coins. I did "try" to dig what I was sure was deep iron but when my wrist is past the entrance to the hole that's at least 12" deep while holding a Lesche trowel. I just don't like digging that deep for nothing with a hand tool. What I did notice is the definate resonating sound that is different on those low iron tones with this coil. Digger is right on with that one. The most cool thing about all of this is there are and still is several people who hunt this park regularly the park attendant told me today when he stopped for a conversation and asked if I had hit the motherload yet. I'm tickled to death and can't wait for the rain the next several days. It is dry dry dry. The moisture should help out the wrist some

When you get done with that 40 X 40 patch, run through it again diagonally. You may hit a few more that are on edge or partially masked. Nice job, so far. Keep us posted! HH Randy

The 3KHz is a different animal...In a good way.

If you are a copper and silver coin hunter you will want to use all 3 kHz (LF) coils(only one available now). It also handles iron better, some say also has better depth, and maybe better on outside interference.

Then what is the downside of a LF coil, not as good on small gold items as the 7.5 (MF) and 18.75 (HF) kHz.

Would be nice to have a 6" LF DD and 10.5" LF DD. Although Barnacle Bill said the 6" HF DD is very good on trashy iron areas and having the best of both worlds picking up the small gold jewelry better than a LF.

Tell you the truth I would like an SEF or slimline, rectangular or elliptical, 10" x 18" or 12" x 15" DD for my X-70 for the large areas to cover on old virgin homestead-farmers fields I want to hunt this summer. May have to revert the my Musketeer Advantage with a CoilTek 15" WOT DD for this work. If I had a MXT I would pick up a 12" x 15" or 15" x 18" SEF DD for it. A 12" x 15" is available for the F75 or T2 in Europe. The BBS and FBS units with big SEF coils are too slow to use on large area fields for this purpose.
