On a new submersible course we just installed through the ice, we need something equivalent to a couple of 9" skier balls that will always be underwater and well be subject to daily 1 atmosphere compression/expansion cycles. Is there a particular skier or gate marker product that wouldn't decay and sink after several years ? Don't need or want a fixed volume float - reduced buoyancy at depth is good in this case. From experience
, is there a Brand of Skier or inflatable Gate markers that are most durable ?
Its the blue float added to the original design - it ensures there is no residual tension from the winch-line on skier or gate buoys when the course is "up"
