I purchased the Digi-Pas® 2-Axis DWL3500XY (Bluetooth model) on the recommendation from Hurco. It was mainly for leveling the 5 axis equipment. What I found is I use it for every leveling process we perform regardless of the application. The Bluetooth feature is the best. You can set and calibrate the level in one single spot and it will give you X and Y real time feedback to your laptop. This is great on large machines. You can make a leveling screw adjustment while being on the floor behind the machine and if you have your computer or Android device you can see it as you make the adjustment. This level will cut a leveling process by 75% no joke! It is the best purchase I have ever made for our service department.
