Kastaway's Magnetic Diver MAGNUM
Now at last, a diver that actually resets itself. No more reeling in yards and yards of line every time the diver is accidentally tripped. Simply lift the rod tip, and then quickly lower it to create slack in the line. This then causes the line to slacken and the diver's magnetic release resets itself. It can be adjusted for light or heavy strikes. All you do is slide the metal plate forward or back to change the sensitivity of the release. Max debth is 60' .
