HAMMERHEAD DIVING SHARK is an aquatic marvel that mimics the realistic swimming motion of a real shark! Featuring a dual motor drive system and bionic spine, this innovative design allows it to swim in all directions – forward, backwards, left and right – while diving up to 1.5 meters (appr. 5 feet) all controlled from the surface with a waterproof remote control. The HAMMERHEAD DIVING SHARK also boasts eerie red glowing eyes and an “auto-pilot mode” that lets it swim straight or in a figure-eight pattern at the push of a button. Not intended for use in salt water. Includes rechargeable LiPo battery (3.7V/350 mAh), USB charging plug and 2 replacement propellers.
