I guess if all you are wanting to do is combine a little cardio with your swimming then this might be ok. the motion to peddle the propeller creates a lot of disruption in the water requiring you to expend an excessive amount of energy to propel yourself through the water. If you are wanting to actually go somewhere while conserving energy, then get yourself a pair of US Divers Jet or Rocket fins and learn to use your ankles with a slight scissoring action with your legs.

Those were the fins to have back in the day, still have a pair in my old dive bag. Probably just rubber mush by now.Quote:

Likely the video provider gave barest glimpses to avert onslaught of patent infringements. Short of a battery powered propeller, vented fins are still the way to make distance.Quote:

I will admit to being an ignoramus WRT patent law Toolmaker51, but how does showing a photo or video of a patented device violate patent rights?
Oh, we have a diver thread! Yeah! I have poor circulation in my feet and subsequently foot cramps are a big limiting factor for my bottom time. Any suggestions for that, aside from losing another hundred pounds?

i.e. shorting his opportunity, possibly a patent pending.
That's minimal display of the mechanism, mounting to the body, about any feature assisting another party design, getting a product marketed before the original. A brief intro like the video is 'Kickstarter'/ GoFundMe type fishing for partners or funds.
I'd compare this to my own issues. Within my not small toolroom, envision tying in sensible courses to a select public, igniting interest in the trades. Think I have banners, descriptions and neon all over town before getting the doors open? Any one with more resources could easily ruin this plan.
I've been moving in shop furniture; storage cabinets, bookcases, worktables etc. Ideal exercise to generate circulation and frequently alleviates cramps as a result. But next load of 6 is Saturday, the last for awhile.Quote:
