The FM handle guard is available in pre-fit sizes or a convenient adjustable version made from a choice of quality plastics: a 1.5 mm Soft, 1.5mm Black-Flex and a 1.5mm White-Flex. White Flex is the stiffest. The 1.5mm versions are very light. The Soft and Black guards are easier to roll for handle changes.

Measure your handle vee from the inside of the handle edge to the joining of the ropes to ensure the correct size is selected (see the photo below). FM Guards are compatible with 12 or 13" handle bars and can be adjusted for length, positioning and width.

Fluid Motion was first to develop and publish the very simple handle guard concept in 2004, using a thin 1/16"  plastic, fastened by tie wraps with a middle stay.  Fluid Motion proudly supports the sport of water-skiing, competitive junior and pro skiers with annual product sponsorships. Visit our team skier page on this site. This video features FM skier Dr. Hermann Nell, who assisted in the development and uses the FM handle guard.  

 The first step to rope-related injuries is prevention.  
1. With each fall there is risk. Try to eliminate all falls and crashes.
2. Make sure your ski is setup to ride smoothly and stably. In particular your fin surface area should be in spec. for safe turns and holding power.
3. Always ski behind the handle and with a tight line. If you encounter slack line discover the reasons why and work to fix them.
4. The speed at which the handle is pulled away from the skier decreases as the line gets shorter. 35 off and above are particularly dangerous if you are experiencing falls, slack rope or have a ski setup that is not able to ride the line length safely and in control. At shorter lines the skier turns back into the handle faster, and at the same time the handle is removed from the skier at a slower rate.
5. Reduce boat speed if something isn't working for you that day. Avoid situations where you feel pressured to "push it" and ski with safety as a priority. 
6. "Pros make it look so easy". While it is a lot of work and requires top athletic training, skiing a well tuned setup on a very short rope will look easy. However, the best skiers in the world are very experienced and well prepared professional athletes, some of the finest in the world in any sport. They are able to ski aggressively but do so in territory they are familiar with and most always in control. Their careers depend on it. So whatever your level, patience and technical understanding is a key element.
