Review on Eyoyo Original Professional Underwater Recorder by Christian Bennett

I didn't think it would be useful; but i tried it because i need something for kids to play with. As luck would have it, at night when I bring this to the boat I throw my keys in the water! After trying unsuccessfully to fish them out, I'm going to start the thing and start looking. It's 10pm now so I didn't think I'd see anything. But. GUESS WHAT!? Infrared light shows the bottom and the water even in the dark! It didn't take long to find my keys; Then take a broom and tie it to the web to grab them from below. It's worth it! I don't know how well this works during the day but it has saved me from calling a tow truck or finding someone brave enough to get my keys.
