This is an extremely compact and space-saving electric jigging machine! A new "reverse connection prevention function" has been added. Even if you turn the power switch ON, the pilot lamp will not light up if the positive and negative terminals are connected in reverse. Of course, it will not operate. The lamp will only light up and operate correctly when connected properly. With a built-in intermittent timer, it makes a tricky movement that strongly appeals to fish! The rod rest and clamp parts use new [NAKAZIMA's universal rod rest]. The battery is 12V only. Please connect the positive and negative terminals correctly. Please note that this is handmade by an amateur, so it is full of imperfections. Please refrain from purchasing if you are sensitive to such things.
