After the high-grader up front (which recovers an important portion of your daily gold), there is initially a 3/8-inch classification screen which allows all the larger-sized material to be immediately discarded as tailings.
The most valuable part of this dredge is the double classification system. Very low hours on the twin 9-HP Honda motors with authentic Proline pumps (best in the world). The 263-Gast compressor allows for two divers. Two additional floatation modules have been added, along with decking so one or two people can get onto the dredge even when it is operating. This is a huge time saver because it allows you to leave the super-fine gold recovery sections alone (without any worry of gold loss from them) until they are worth the time to clean-up. This 6-incher is a step up from my own Pro-Mack 5-incher (which is the 3 rd generation of double screen classification) largely because we have added a high-grade gold recovery section at the head of the box which recovers all the larger sized gold and has preliminary fine gold recovery section that can be cleaned up every day with minimal effort.
