This is a review of the #Lomvum 393ft Laser Measure - LOMVUM Laser Distance Measure with Mute Function Large LCD Backlight Display Measure Distance,Area and Volume,Pythagorean Mode Battery Included. #RankBoosterReview #Sponsored. This laser measure is quite handy when measuring large areas. I have measured quite a few things as I had to make sure there was enough room for a new couch and find out how large of a pool cover I required. Using it is simple enough, you turn it on and press the measure button and aim the laser at the glossy card that is included. The measurements were given almost instantaneously. The unit itself is quite small and would easily fit into a child's hand. I like the fact that you can measure to the front or the rear of the unit. However for areas that are smaller than the unit itself, you wil not be able to laser measure due to space limitations.
