HF COIL VERSE THE LF COIL

[Calabash Digger]

A test on depth and emi to see the differences in the two coils.

You are going to be happy running the HF coil in 28 kHz at your relic sites....you will surprised how many mid conductors the LF coil missed

Ted - agree. I think running it at 28 khz will make it a button/brass magnet at relic sites. Can always throttle back to 14 khz if you want to hit high conductors, though 26 khz will ferret out high conductors at decent depth based on my beach experiences.

I used it only for about a half hour in PA, although nothing great, I pulled rivets (pictured), bullets, copper and lantern scraps that the LF coil simply did not hit.

Just a note on 74 kHz, I think I'm going to stay away from this setting for relics, it seems big iron fools it (me) way too often. I may just have to learn the length of the tone though and just dig the real quick short length tones.
