"Thank you a million times over! That's about how many times I have used it in the field to calculate all kinds of numbers in feet and inches. This gem has saved me a lot of money and is a no-brainer for anyone working in the field."

Tim Newsome,

Martinez, GA

"I use it on every house. I just tote it like I do nails in my nail apron. You really need one if you are going to put rafters on a house. It's just highly invaluable. You figure up the measurements one time and you cut the rafters. You don't have to check them."

"Well Worth The $$. I have had many Construction Masters over the years and love the format. Now with the app on my phone I never am without it. The format is just like the hand held units so nothing new to learn. Like the heading says it is worth the money."
