This mini jet ski is the latest and greatest aquatic accessory. The Seabob Cayago F7 is not what you would imagine a jet ski to be; instead of being a giant, heavy vehicle, you must hook it onto the back of your truck.

When the warm weather hits, you will want to hit the beach to catch some rays. You can use this Seabob to travel up to 9 miles an hour, both on top of the water and underneath it. Of course, since it can move speedily as you are submersed, it limits your depth—don’t try and go explore the depths of the ocean.

For your safety, all underwater models from Seabob are set to a maximum depth of 2.5 meters for the average user. However, scuba divers can set it to a depth of 40 meters.
