This is a new option for the A-55 which can be factory installed or bolted on to your existing A-55 with simple tools. The drag brake allows the field technician to control the descent of the sounding weight or sediment sampler from the A-55 without cranking it the whole way down to the water. Also, it is a safety feature which allows the unit to automatically brake if the operator would lose grip on the handle during lowering or if a sounding weight is snagged by large debris carried in a fast-moving flow. The operator turns a collar to select a line tension at which the brake will slip. If that tension is reached, the brake will slip, thereby maintaining the set amount of tension while allowing the line to pay out from the reel drum.
