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."
