For years I used a Vibra-tector for snorkeling local freshwater swimming holes. While it produced some nice jewelry, I was less than satisfied with its sensitivity and utter lack of discrimination (being a PI, it hits WAY too hard on nails and other small iron).
I decided to stuff the guts of my Sidewinder into an Otterbox 2500. Sheet-lead inside makes it sink. I added some submersible earbuds and an inline volume control. You have to grip the shaft in front of the box to swing it. 4" coil affixed.
Not too fancy looking but it should produce without having to dig nails and it's got better sens. than the vibra-tector ever had.
I'll be taking it out for its maiden voyage once the floods abate.
