A stainless steel angle finder with an LCD head: open the two arms against a corner, and it reads the angle to a tenth of a degree instead of leaving you to eyeball a bevel protractor. It has a hold function so you can lock the reading, carry it to the saw, and set the miter without the arms shifting on the way. The 7-inch arms are the practical size for crown molding, baseboard returns, and picture framing, and it ships in a hard case so the head does not get crushed in a tool bag. Best fit: trimming out a room where no corner is actually 90 degrees, deck railings, and anyone whose miters keep closing on one side.
Pros
- Reads to a tenth of a degree instead of an eyeballed protractor mark
- Hold function locks the reading so it survives the walk to the saw
- Stainless arms and a hard case, not a flexing plastic body
- 7-inch length suits molding, framing, and railing work
Cons
- The 7-inch arms are short for measuring across a wide panel or a long rafter
Frequently asked questions
Does it show the miter angle or the corner angle?
It reads the actual corner angle. For a miter cut on two pieces meeting at that corner, halve the reading.
Does the reading stay put when I move it?
Yes, the hold function locks the display so the number does not change as the arms shift on the way to the saw.
What powers it?
It runs on a small battery in the head. Keep a spare if you are working a long trim job.
Can I use it as a straightedge or ruler too?
The arms are marked and stainless, so they work for short marking tasks, but at 7 inches it is not a substitute for a combination square.
