Old School Stingers??? (Spring-loaded vs. screw-type)
Apropos getting in and out of a puddle while it still is hot:
Actually the screw type is the old school stinger. It allows you to mount two electrodes. Bend #2 out of the way to be stand-by, and continue within seconds after #1 has been spent.
That is something you can not do with the spring-loaded.
