Earlier in September I had a chance to dive with Peter Scott and check out his new Dol-fin. It is basically a monofin with a high aspect ratio blade. Interestingly, the blade has much the same dimensions as the power blade of my Aqueon. However, unlike the Aqueon, it is very light in weight and low in drag. I think the Aqueon has more power though.

Peter's Dol-fin is a prototype, built by someone in Arizona. So, sorry, you can't buy one yet and I don't have a link to the inventor/manufacturer.

Have a look at the video below to see the Dol-fin in action:

I've made a third video of my experiences with the Aqueon. This one is about constant ballast diving on a line.

I had the Aqueon in the water for the second time on March 1. I knew this time to keep the kick tighter and to rely mostly on the backwards surface dive. I was much more comfortable with it this time and spent some time zipping around on the surface and seeing how far I could launch myself out of the water with it.

Below is a video from that day's experience:

I took my Aqueon for a dive at Porteau Cove on February 23, just a few days after receiving it via courier. I was very excited to be using it for the first time but there were a number of things that I had to relearn:

The Aqueon is a swim fin unlike any other that you will see. Unlike monofins or bifins which mount on and extend the feet, the Aqueon is mounted on the lower legs. The swimming blades are actually forward of the mounting point, moving up and down below the wearer's navel. This device was invented in the early 1970s by Calvin Gongwer of Innerspace Thrusters.
