Nothing new about free diving with scooters, been around for decades. I used to play myself with DPVs and breathhold drops in the 1970's. Guys were probably doing long before that time too.

Despite all that, IT SEEMS NEW. There's playing and then there is doing new things or perhaps old things better. It might be free diving more efficiently, with technique developments and better scooters. I know there are mixed feelings about it but the sit on top aspect of the Apollo is a deal maker for me. I think Dive-X has developed an add on to make theirs sit on top as well. Only seen it in a video never in person. Sit on top has a lot going for it particularly when shooting pictures/video. Hands free and minute position control through unconscious fin steering are the way to go in my opinion. I wouldn't go back to a conventional scooter tow setup myself at this point despite using that system for over 15 years previously.

The mobility and freedom are amazing both in lateral and vertical dives. I am an average free diver and yet the boost in capability is sure a lot of fun. A scooter is the only way many wrecks in deeper water can be dived in this area, there is too much current for conventional diving. There are downsides and cautions of course, things like planning for and coping with power failures, DCS issues, UW collisions, etc.. Still, all types of diving have problems, contingencies, technological and technique solutions and management strategies. As you are practicing something like apnea at rest, it is easy to achieve more than practical with fins and without pushing that hard. For this later reason the degree of safety "might" exceed conventional fin swimming in some dives?

I am still learning about free diving with scooters but the more I do it, the more I like it. Something addictive about it. There are a lot of videos showing dives on a variety of sites at: Something Rich And Strange ... Diving Tales From The Water Underworld - FKA Kiteboarding Forums (http://fksa.org/forumdisplay.php?f=92) Not pushing anything but the novelty of scooter free diving but if I were in retail or instruction, I would take a hard look at it. One thing is for sure, doing this without proper training and preparation it has the potential to be particularly dangerous. With proper preparation and technique, different story I think.

Does anyone else feel this way about scooter free diving at this point?

Had a Tekna for many years, went through three rebuilds before it was time to replace it. It was a good scooter but tow behind in design. I used it with a bridle when SCUBA diving and with a PVC tee seat for easy dismounting when free diving. Went through several Seadoos in more recent years, gave up on them due to low build quality particularly the Explorer (went through four of them all with fabrication defects).

I rented an Apollo Evolution through Dive Tech on Grand Cayman for free diving on the wall there. It was an incredible experience and my first exposure to a sit on top design scooter. There's a video about that at: VIDEO - Deeper Scooter Free Diving The Cayman Wall - FKA Kiteboarding Forums (http://fksa.org/showthread.php?t=4615)

The video quality is fairly poor but there are some still shots of the scooter in there.

There are a lot of scooter free diving videos at: Something Rich And Strange ... Diving Tales From The Water Underworld - FKA Kiteboarding Forums (http://fksa.org/forumdisplay.php?f=92)

There is a recent one where I have some footage of another diver on the scooter to give you a better idea of operation. It also includes some pretty nice dolphin footage at: Diving With The Dolphins Of Sataya (Dolphin Reef), Red Sea - A Video - FKA Kiteboarding Forums (http://fksa.org/showthread.php?t=8720) If it wasn't for the scooter I probably would have had about a minute or two combined video max. Fortunately, it seems the dolphins found it interesting enough to stay around for a while. Being able to swim with them submerged for what seemed several hundred feet at times was a unique experience. Like joining the pod all be it temporarily. A still from the video appears below:

A typical tow behind bridle setup for comparison. I used something similar for beach dives to the 90 ft. ledge off Deerfield years back. You actually would have some upper body fatigue after a while from just steering particularly in current after an extended run.

Steering is extremely easy and response using fins. You don't even think about it after a while, can do 360s, barrel rolls, effortlessly. The power on the Apollo Evolution is applied by pulling up on a rod secured to the side of the saddle. This is one potential problem area as you need to push the rod down to kill the motor. In theory, the scooter might run off without you should you separate. I put in a simple deadman turnoff on mine consisting of a nylon line connected to a quick disconnect and weak link to my belt. Another issue is if you hit, you hit head first. I've done a lot of wrecks, penetrations, etc. to where this hasn't been a problem, yet! Still, it is something to be careful about, even thought about wearing a helmet for limited protection on wrecks, sinks, etc.. Despite all this, wouldn't go back to a tow behind design lightly at all. If you're a diving instructor, Apollo even has a discount program.

A contrasting opinion in some ways from an experienced scooter free diver:

The Cuda system is not really heavy. We have taken our Cudas around the world (quite literally) with only two checked bags (that includes scooters, complete scuba gear, clothes, everything).

I am reasonably sure that there is a bit of performance difference between the Dive-X offering (Cuda with a saddle) and the scooters you've mentioned (SeaDoo, Tekna, Apollo w/saddle).





Although I would agree that scooter freediving gives one a safer dive, my experience is that this is only if all things are equal: depth, dive time, breathe up.

The nature of scooter freediving makes it very easy to get deep and stay there for awhile. Your mind is occupied by all the things whizzing past, so, it's easy to get distracted. This makes it a perfect setup for deep water blackout; and to make things worse, buddy contact can become problematic, too, as a buddy on the surface is noticabally slower than the one submerged. All these conspire to make scooter freediving actually more dangerous, IMHO.

Thus, whenever I work with a freediver who is starting use of a scooter, I emphasise the hazards. I kind of made up the "rule of halves": don't scooter deeper than half your performance depth or longer than half your static (this is a work in progress). I limit myself to 20 meters and 2:15, and in fact I have the alarms on my D4 set to those specs.

Scooter freediving is an awesome enhancement to what is already an intoxicating sport. Enjoy!


All the best, James
