Using the Apollo Evolution scooter hands free operation is easy for equalizing and for shooting images while riding along. Just shot a clip on the Spiegel Grove off Key Largo, FL over the weekend using a Canon G9 "still" camera. The visibility was quite poor but it seems the camera could see better than I could. I don't recommend scooter free diving in strong current and poor viz. especially in the impact and tangle rich environment of a wreck. There are other cautions that go with scooter free diving, some of which are considered at the link below.
On to the video ...
