Who Should Buy This

Digital angle finders are used for measuring the inside and outside of angles. They are used in many different tasks that one might need on a regular basis for projects including installing crown molding, framing projects, building stairs, constructing patios, automotive repairs, installing flooring and tiling and woodworking, carpentry and contractor projects.

They are used by woodworkers, contractors, floor installers, framers, remodelers, construction workers, tile workers, automotive workers, carpenters, satellite dish installers and others who need a precise angle measurement on their projects.   These tools are often seen in woodworker’s tool boxes and are very beneficial to building projects of all kinds.

What Makes a Good Digital Angle Finder?

There are several things that you will want to look for when it comes to choosing a great digital angle finder. One of the most important features to look for is a locking feature that allows the users to lock the arms in at any angle. This is important because if you can’t lock the arms, you will have to try to hold the arms in place which makes it difficult to get an exact reading.

digital angle finderThe display should be easy-to-read and large in size so you are not squinting to see the readings.  If the display is a back-lit style, then that’s even better. An auto-off feature is important for extending battery life. Sometimes a tool gets set down and not needed for an hour or so and you wouldn’t want the battery to continue to be used during this time. The auto-off feature allows the device to power off on its own and save its battery.

You want to choose a model that has strong, durable construction materials like stainless steel which is rust resistant and corrosion resistant.  You also want to make sure that the measurement markings are deeply etched so they don’t wear off with extended use.

A built-in level is always a favorite feature with users so they know that the surfaces and objects they are working on are level. Reversible display is also good and allows the user to flip the display toward you,

You want to find models with a good memory function that locks in the angle that you have set.  This prevents the user from having to repeatedly re-measure an angle that is used often.
