Big Blue Goodman Handle This is a neoprene Goodman handle by Big Blue. Their Goodman handle is a little different that the other ones out there. They use a double retention strap. The one strap sits on top of your hand the other strap sits on your wrist this keeps the light from falling off your hand. The Goodman handle fits most lights that are the 1” diameter style. This includes the Light Monkey Rat Jr, Halcyon, Big Blue of course and others. This also works great for many other applications.
