Speedway Motors Liquid Level Tool with 12 Foot Hose, Dual 12 Inch Impact-Resistant Containers for Leveling Scale Pads, Wheel Alignment Setups and Chassis Setup Accuracy

A very simple and inexpensive solution to a necessary issue, leveling your setup area. No instructions included but simple if you know whats going on. Learned when I was a kid from a ""Lassie"" episode that ""water seeks its own level"". Add a bit of the dye to water, I used distilled and added a bit of cool suit conditioner to prevent mold buildup. A couple drops of bleach will work. Add enough water so that both tubes read ""zero"" when placed next to each other. Tap tubing to remove all bubbles. Tube markings don't perfectly match but they are close enough. Level individual scales and then match each scale with the Liquid Level. Sure beats Longacres $200+ laser solution!
