The 45″ is 10 inches wide and 45 inches long weighing only 9 pounds. The riffles are designed for superior recovery under different water and gravel conditions. The first few riffles are stream riffles to make it easier for the water to start to move the material, followed by Hungarian riffles to enhance recovery if greater stream volume is available. A section of diamond cut raised aluminum is included for enhanced fine gold recovery. The steel riffles are plated for decades of durable service. Accessories are available to convert the 45 inch sluice into a power hibanker or a dredge. The 45 inch sluice has a removable flare.
