Question: the product shows a kite surfing dvd is bought together with this, can this actually be used on the water?
Document: used few times in various conditions, easy to use, good to learn the basis of kite handling...good quality construction.
I really like this kite. Its simple and has helped me better understand the wind windows and the general kite patterns that I'll need when I learn to kite surf in the water. Great for fun, and for learning kite-boarding fundamentals.
You need decent wind to launch this kite, but it provides a nice training experience for windsurfing. Overall good product, but sometimes difficult to launch in lighter wind conditions.
The kite has a nice bag that holds the kite and the bar and lines, but I also cary a harness so the backback helps.I self launch this kite by laying it on its back andputting 2 water bottles on the traiing edge. When the lines come snug the kite fills with air and stands up. One little pull and the bottles roll off and the kite soars into action.
My 14 year old son and 12 year old daughter love to fly as well. I purchased a pair of bicycle gloves to cut down on blisters. Even though it is only a 2-line kite it's easy to self launch - just face into the wind and place a couple of water bottles on the trailing edge then lift the bar up and start pulling. I rarely crash anymore so relaunch is not a problem. Even when I do crash, it's not that hard to fetch the water bottles for relaunching.
I bought this kite in the autumn of 2012. After a couple of flights by myself, my daughter and several friends, we have all mastered it's speed, power and agility. Just recently, it was put to the test as Hurricane Sandy approached the Massachusetts shoreline. In the 30+ mile per hour winds it was a handfull but flew beautifully! We had it up for at least an hour, trading off when each of us got tired.
This kite is great! It has tons of power and i love the control bar it comes with. i would recommend it to anyone. it is the best 3M kite out there hands down. It does not come in the color in the picture which i am happy with. It comes in black and yellow. I dont even live by the beach, i just bought it for when i visit the beach. i took it down to a small field with a light breeze and the thing wore me out.
Bought this kite to gain some flying time in preperation to learning to kiteboard this spring. I've only flown it a few times, but have a grin on my face everytime I get it flying. Even in 8kts of breeze the kite once brought into the power window will still pull pretty good. And in breeze over 15kts it gets really fun. If your looking for a kite to practice and keep sharp this is the perfect choice.
I bought this as a birthday present to myself about 5 months ago with the intention of learning how to kiteboard. I fly it on my lunch hour at work nearly every day and often after work on the way home as well (winds permitting). It's a great workout. I live in Oklahoma, "where the wind comes right behind the rain", and while there are a number of nearby large lakes I train on the grass lands and not the beach. This kite is well made and durable.
My son and I have been having tremendous fun with this kite. It's really easy to fly. In four outings we have already learned to do fast loops.
