Review on 📐 Contractors' Self-Leveling CO Z Horizontal Dual Module by Mike Walters

Works great indoors but useless outdoors in daylight. The laser seems very weak unless used in a dark place. We are installing a swimming pool in our backyard and I was hoping to use it myself to ensure the base of the pool wall is level so we can proceed to the next step of the installation. I had to bite the bullet and buy a Dewalt Optical Transport Kit, which would require someone else's help.
