Testimonials
So all day long, I'm checking for flatness, measuring things and checking scale length and the Tri-beam has been indispensable for that. It has really simplified my day by having 1 tool hanging on my bench rather than having to go find a ruler, straightedge or do the math to measure scale length. Also, what I really like about the Tri-Beam is the accuracy of the edges. I also like the triangular form factor. It makes it very easy to hold when assessing a neck for flatness or using the SAE or Metric ruler.
