Feature: 1. Advanced Ultrasonic Sealing Technology: The boat's hull is constructed using ultrasonic welding technology, seamlessly fusing the upper and lower shells into one cohesive unit. This not only enhances the boat's aesthetic appeal but also doubles its waterproof capabilities, ensuring long-lasting durability even in challenging water conditions. 2. Stunning LED Light Effects: Featuring a transparent cover with an LED light, this remote control speedboat offers vibrant red, blue, and green lighting effects. The lights illuminate the boat beautifully, making it stand out both day and night. Enjoy smooth navigation during nighttime races and add a dazzling visual element to your water games. 3. Smart 2.4GHz Remote Control System: Equipped with a 2.4GHz intelligent frequency remote control, this toy boat provides interference-free operation up to 50 meters. Multiple boats can be operated simultaneously within this range without any signal disruption, perfect for organized races or casual play with friends. 4. Low Battery Warning System: To prevent accidental loss of the boat, an integrated low battery warning system alerts users when the voltage drops too low. The boat's lights will flash rapidly, and the controller will emit a "beeping" sound, signaling it's time to retrieve the boat. This feature ensures you never lose track of your vessel during playtime. 5. Water-Sensing Safety Start Mechanism: Designed with safety in mind, the boat includes a water-sensing start mechanism that activates the engine only when the boat is submerged in water. This prevents accidental starts on land, reducing the risk of damage and ensuring safer use, especially for children.
