Many people have a favourite heart rate monitor or GPS watch that they use in other outdoor activities. Wearing a watch on your wrist prevents you from having real time data without stopping paddling to check your watch. An option would be to use the leash plugs in many hard boards for the bungee rigging (something like the leash plug adapters from Ram Mounts or YakAttack) - this would however mean you have it mounted on one side of the board, and you'd need a series of parts other than the adapter to mount your preferred device. This option works well with race boards that have a front leash plug in the center of the board.
A reasonably priced and flexible option is shown below:
- SUP Buddy Dashboard
- 9cm pool noodle
- 1m 3mm static cord for safety tether
- 2 re-usable nylon ties
- 2 x 3cm length of velcro (varies depending on watch strap thickness)
Simply slice off one side of the pool noodle to get a flat surface wide enough to stick the velcro to. Carve a slot in the centre to act as a channel for the watch strap. Loop the cord through the pool noodle and tie a bowline knot. Tie a an overhand loop into the other end, and you're ready to assemble.
The system is easy to attach and remove from the board and quick to disassemble for cleaning and drying. Happy Paddling....
