Perfect for swimming, snorkeling, and diving, Geneinno S2 lets you cruise through the ocean up to 100ft deep. With built-in 97Wh capacity, it offers 60 minutes of running time at max speed of 2.7mph. It can be monitored by a smart app on your phone — speed, depth, distance, light, and battery — and share that information once finished diving. You can also mount a GoPro so you can record underwater wonders. With a child safety lock, you can control S2 when used to train kids for swimming.
