You can buy the Manta Jr or Sr with what is called a cave cam. Here are 2 photos of it. The reel operates manually like normal until you turn it. When you do it locks the handle up so that the ratchet is disengaged.
You will also see how the handle is only lifted in the rear. Now imagine the exact opposite. That is how it is possible to not fully disengage the spool on deployment. Thus resulting in the reel jamming.
