This new underwater drone could revolutionize fishing

During our current golden age of drone technology, "the sky is definitely not the limit." With submersible drones invading our oceans, rivers, and lakes, the Power​Ray ($1,799) might be the one that changes fishing the most. When fully outfitted, the device can detect fish to a depth of 70 meters, use sonar to measure fish distribution, transmit real-time video, and help place your bait at an exact depth. For $90 more than the price below, you'll also get VR goggles — "so you can feel like you're riding the drone's body as you navigate it through the depths."
