In the theater of life, we do play games for enjoyment and the value of identifying what our own bodies can do. Human health, and its physical happiness, is a glorious thing. Tragic mishaps are not. I do not charge for life saving devices.
The cost of skiing snow can be an avalanche. The most correct method of protecting a skier: is to provide the personal product “like this”.
IF you produce a small anchor that is probably released with a parachute like cord. Then those anchors probably 3 of different lengths of about forty feet (high speed snow from behind); the anchors will fall behind in the moving snow/ becoming slowed and stopped as weight moves over them. The vest attached to the anchors and worn by the skier, is then slowed within that movement of snow material. Which causes the skier buried in the snow that has not yet stopped/ to be pulled to the surface by those cords coming from those anchors which have stopped moving. The anchors must be attached to the vest, so that, when stretched: they tilt the body vest and all upward; against the snow movement. Which then causes the snow to be forced down, and the body to be forced up. In a slow moving snow that you cannot escape the path of turning into the snow; with about ten feet of line is likely better. experimentation forms the choice.
The correct placement of the anchor cords in the middle to lower back: will include each anchor that look like “large plastic, cone shaped washers (each facing opposite) that are collapsible, so as to be comfortable and aesthetic; on the vest and pushed out by a suitable concave spring (stabilizes the anchor form), when released. Making an appropriate sized anchor in the snow, which can then move a bit; in relation to the pull being exerted by the body. This arrangement must also include a smell and dye packet: which will open automatically when the anchor is released. for location awareness.
The reality of turning a tumbling body in the right direction: is governed by the length of the cords; and luck. Different lengths will impact the body as each begins to tighten. Which means if the tug starts on one side of the body, the pull will expand through the center and then to the other side; in order. So as to give a turning effect. That specific element of exactly how and where; requires experimentation. knowledge about what to do when caught in the tumble will also help/ although after the first few seconds, your ability to tell which way is up or down will fade. the “parachute cord” will pull a pin on each anchor: that then releases the mechanism; and will contain enough “fragments” of style to encourage its automatic release. IF an air bag was inflated in this process behind the vest containing the anchors; so as to give a ballooning effect: that would go a long way in turning the body itself into a position that travels up, and not in any other direction. IF it contained a very slow release so as to deflate in five minutes or so: that would greatly increase the probability of survival and even escape.
