Interested in converting our Accufloat course to a sinking version. Planning to construct a "homemade" version of an Accusink, but if anyone has a used Accusink or Wally Skier available at a reasonable price, I'd appreciate a reply. Also, if anyone has pearls regarding construction of a sinking unit from scratch, feel free to provide input.
The course is in variable water depth from 25-100 feet. Plan is to use 5 gallon sealed pails for air bladders with slightly positive buoyancy when saturated, and lead weights dangling about 10-15 feet above bottom attached to the pails. When the course is sunk, this will keep it at an even depth. When the pails are air filled, the combination of buoyant pail and negatively buoyant lead weight creates slight negative buoyancy, just enough to hold the assembly down.
1/4" high pressure air hose will supply the needed compressed air, provided by a refillable portable compressed air tank.
Thanks in advance for input.
