Question: If you topple over, how easy is it to get back on?
Document: I bought 2 of these since they looked so cool and also like a lot of fun. I am a big fan of watersports. However, a friend of mine and I spent many hours over 2-3 days trying to get it to go, but all it did was sink every time. The blade is extremely sharp so getting it back to the dock to try again, after it sinks, can be a challenge to avoid cutting yourself.
good work out not from riding, rather towing back to dock once a stall occurs. there is no recovery when your bounce gets out of sync. Since water starts are not an option, one is left towing this awkward thing back to shore. Great way to look like a fool & clutz.
I had tried one of the at a friends cottage and decided to get my own.It definitely takes some getting used to (and ideally somebody who knows how to do it to direct you)... most people would just sink straight away their first few tries (and that was enough to make some quit).Anyway, its a fun toy that is a intense cardio workout.
We...(adult male and female, 19 yr. old male and female) all tried using this product with little success. The accompanying video makes it look so easy, but it is far from that. However my biggest complaint is with how cheaply it is made. Nearly every yellow piece of plastic has cracked and/or broken off. I even spoke with someone at "[...]" who claimed to be the inventor of this thing.
6 years ago my aunt bought an aqua skipper for our lake house. It took multiple days of trying (our lake is cold so our tries were short) before one friend got it enough to return to the dock. Once the first person had it the skills were transferable and now we can get any determined person to at least feel like they have success on their first day.
Faith matters.Now I just want to do more aquaskipping, I can't wait holydays to do more.It's great fun, I like it a lot.I guess I can teach the basics to other people, but I'm far from the expert level, it's a long way.Get in shape: when you learn there's nothing more cardio. In less than 30s my heart maxed BPM like crazy and lungs where short of air. That's the limiting factor, not the legs power.
when they bent. So they put these cheap (his words) plastic pcs. on so that people would only have to replace the plastic when THEY broke. He said they will break when, for example, the aquaskipper hits the bottom of the lake with rocks/stones, or it hits the dock. He said it is very hard to use so people are in fact going to sink to the bottom when learning to use it.
regularly. Guaranteed they will break. I heartily agree with the previous post. Save your money.
Yes, it took about 1/2 a day to learn how to use the AquaSkipper. You have to jump - really hard on the platform. But then it was a lot of fun, and a great whole body and cardio workout. I like that it doesn't use any noxious gas that pollutes the water. My Uncle has one too and since boats and jet skis are banned in the lake near his house, the AquaSkipper is perfect for him.
We'll often go out to circle around a passing boater. We can even skip through waves (which we didn't think possible at first as they would always sink us). I'm sure people with warmer water could learn faster.The limiting factor now is how long I can keep jumping. 300 yards is about my current max distance.
Answer: no
