From the Field Cordless Evolution Classic ProShot power … fine finish refinement By Scott Burt he Graco ProShot II rolled out last year, with some pretty significant changes from the previous ProShot and ProShot Fine Finish models. Interestingly, this second-generation handheld combines many of the best qualities of both its battery-powered predecessors and brings some new improvements of its own, while still delivering the mobility and convenience that handheld users want and need. T WHAT IS THE PROSHOT II? The ProShot II blends many of the best features of the first-generation ProShot and Fine Finish models. The original ProShot was rated up to 2,000 psi with no ability to adjust the pressure; it ran full strength all the time. The old ProShot Fine Finish, on the other hand, was rated up to 1,500 psi and did have a pressure control feature. The ProShot body was bulkier than the Fine Finish, which was narrower and more agile. The new-generation ProShot II is built on the more slim-line Fine Finish-style chassis, which makes it sportier and easier to handle. However, it comes with the higher 2,000 psi pressure rating of the old ProShot AND a ProControl pressure control system. In other words, you are not locked into a constant 2,000 psi – you can turn the pressure down. The lack of this feature in the old 2,000 psi ProShot made it a bit of a material hog and required users to modify their spray technique to keep up with material flow. On an open road that was desirable, but it eliminated the ProShot from finer work tasks. Being able to turn it down in 12 • May 2013 APC The addition of a flexible rubber suction tube in the cup allows users to spray from almost any angle. many situations is critical. This improvement also reduces overspray, which plagued the first generation of the ProShot. Being able to turn pressure down also allows the user to reduce higher-viscosity materials, which helps to further reduce overspray and produce better finishes at lower pressures. Thinning was usually neither necessary nor a good idea with the original ProShot. The battery pack has been increased from an 18-volt lithium ion to a 20-volt. It was no secret that the previous-generation battery pack was not sufficient. The new battery delivers more consistent power throughout the cycle. It comes with two 20-volt batteries and a charger. I found that the new battery functions well for approximately 4 quarts, or about 40 minutes. A further functional improvement is the addition of a flexible rubber suction tube in the cup, replacing the old molded plastic version. This allows for more complete use of all the material in the cup. It also gives the user the ability to spray at just about any angle, and the tube will find the material in the cup for uninterrupted flow. In the past, if you sprayed at certain angles, you would be moving the material in the cup away from the location of the suction tube.
