Ive been detecting since 1975 - neevr heard of this guy Cory
I know a guy that was finding gold coins on a Calif. wreck yrs ago
great whites came in after he hunted for a short while each time - bout the 6 time out - one got him
so his machine did not scare them away
I know others that have had close encounters too - met a guy at a Ct. bch yrs ago
said he used to live in Clearwater area and "USED" to detect in water - he was hunting
waist deep and all of a sudden lifeguard and others were screaming from shore - "shark!"
as he truned toward them - something ripped his long handled scoop from his hand and took off with it
After crapping his pants (which i think will scare them away) he practically walked (ran) on water
to get in - Life guards said he could see dorsal fin and tail fin and it was a good size one
Ive heard other stories over the yrs too
Have seen professional treasure hunters vids where sharks were hanging around
too - so dont know where he got his info - I dont believe he did any research himself
now magnetometers I think make a knocking sound underwater and may disturb them
but we are talking MD'ers
Tthink of this - if they did repel sharks - then Why hasnt someone made a mini box that
has the same circuitry as a detector - for divers to wear

or large buoys with large boxes with detector circuitry to place in swimming areas
like off Australia's beaches as well as a lot of ours - who ever develops one would be rich world wide
Ive had fishermen get po'ed when Im in the water and say Im scaring all them fish away
both in fresh and salt and had them yell at me - Ive told a few guys to cast near me cause there was
a ton around me - that my coil was attracting them - I thought yrs ago (in the 90s) of placing
one of my old PIs way out on the bottom and leaving it on - (batteries last long time in old PIs)
trying to see if it could be used as a fish attracter and if so - i could sell the idea
