Pulse induction versus vlf detectors

[Tigerdude]

I have noticed lately people using this pulse induction detectors. THey look heavy. It seems the advantage they have is that they detect deep. I like to relic hunt. Maybe its me but I find plenty from 2 to 8 inches. If you are a relic hunter, what situations would you want a pulse detector. A clean field,for example? Do they work in trashy areas. They don't seem to "pinpoint " well as the holes dug seem large for the items recovered. Just curious. I'll hang up and listen.

From what I see they use those down in the VA relic hunts in the fields that have been hammered over the decades to try to eke out the deep stuff.

I have a water pulse and can get goodies down 2ft range - but I use my vlf
in all metal and have pulled lg musketballs and minies down just as deep
In CW areas that have been hammered
3 ringer in center of hole - down about 20 ins. others had passed over it
I got a whisper and dug

a pulse will pick up everything - tiniest nails and down deep - it will pick up cannon balls and large iron frags down real deep
so be prepared to dig a lot - I always thought it would be great to try my pulse in a field - but there is so much tiny iron
would be crazy- at least with my vlf - I can click over and check and weed out the tiny junk

There's a book called "Pulsepower" by Clive Clynick if you want to learn how to use a pulse induction unit.

There is lots to be said on the topic of VLF vs Pulse Induction (PI). Check out the threads in the prospecting forums. In a nut shell VLF allows for discrimination and typically will not go as deep as a PI. PI's are dig everything machines, though some have minor discrimination, and are relatively immune to ground minerals so they punch deeper than most VLF's. I've an associate who uses a GPX 4500 for relics however he carries a big shovel.

read Clive's book and you will have a MUCH different viewpoint. I would say not for most beginners. Don't waste your time if you can't afford about $15 for the book.
