6" DD vs 6" MF

[Anonymous]

Can anyone tell me which is deeper? I have a 6" 7.5, but am curious if the 6" DD 18.75 goes deeper on coins.
Thanks

1. Depends on soil.
2. Depends on high conductivity vs low conductivity coins.

I'm in a low mineralization soil, and mainly looking for silver, and if lucky, jewelery.
Thanks

if your looking for silver, I'd vote for the 7.5 med freq coil

Lower Frequencies tend to penetrate the ground a little deeper and are good for coins (especially silver) and Higher frequencies will detect smaller targets (like smaller-than-coin Gold nuggets). For Gold nuggets, in different sizes and at different depths, anything close to 20khz is considered "ideal"

All in all, the depth will be similar with these two coils. The smaller 6" coils tend to be more sensitive to smaller targets and this may likely relate to field-density being stronger/thicker on smaller coils. If you are a coin/relic hunter, the Medium frequency or even the Low frequency coils are best when hunting in parks or areas of low mineralization...but the Higher frequency 18.75khz coils are arguably better for hunting beaches where salinity or mineralization

Cheers,

Thanks guys,
I have a 6" MF, and just wondered If the 18.75 may be better for what I'm hunting for even though I also want jewelry, but I'm sure you are right, and the MF will do fine as well. There was a 6" 18.75 for sale on here, ans just wanted to jump on it if it would give me and edge. Really thinking about a 9" 3kHz, even though it will probable not be very good for jewelry.
Thanks everyone.
