Good job done by developers team to make it simple to install, configure and run any kind of machine or drill rig within minutes. The ability to save my work as soon as I have finished with every operation makes me feel safe while using this product. I haven't encountered anything bad about winlog drilling application. If you are looking for an efficient tool which helps you keep track of all boreholes operations, then definitely go for WinLog.

Keeping records of each borehole and its status is made easier by keeping it organized; thus giving us time to check out our performance at regular intervals.
