Designed for the quality-conscious shop with a lower service volume, the DSP7705 from Hunter Engineering is a rugged economy balancer with features that ease service and provide fast, accurate results, according to the maker. The DSP7705 handles a wide range of wheel designs up to 44 inches in diameter and 20 inches in width. The powerful motor can spin assemblies up to 150 pounds repeatedly without overheating, Hunter said. The display uses easy-to-understand graphics and simple controls to help operators enter wheel dimensions, determine the best weight placement and navigate through balancing procedures.
