Here is what each one does well:

1. GemRed Digital Angle Finder

Click for Price

This multi-purpose tool is a digital protractor and a ruler in one. It is compact and easy to use, with two stainless steel ruler arms joined at a hinge that holds a small digital display.

The arms have etched markings for measuring, and the digital readout shows the angle between them. It offers good accuracy for both professional and DIY use. It runs on a lithium coin-cell battery.

Pros:

The stainless steel arms resist wear, and the etched markings are easy to read.

The readings appear on a small digital screen, so you do not have to interpret a dial.

The arms are straight and flat, so they sit well against the surfaces you are measuring.

The hinge locks it in place. With just a simple twist, you can effectively lock it in place.

The zero function is easy to use as well. You can even use it to create odd obtuse or acute angles.

It is affordable for a digital tool.

It folds to a small size, so you can easily stash it in your kit or pocket.

Cons:

Some said the on/off switch is very sensitive. Even just a small movement of the arm sets it on.

2. Johnson Level & Tool 700 Magnetic Angle Locator

You don’t need to spend a lot of money to find a good angle finder. This analog angle locator reads from 0 to 90 degrees in each quadrant, with the scale printed behind a clear lens.

A magnet in the base holds it on steel surfaces, such as a saw blade, conduit, or ductwork. The molded body stands up to bumps on the job site.

Pros:

Its low price is one of its strongest features.

It is durable. The body is made from an impact-resistant plastic material. You can easily bring it with you and not worry that it will get damaged from all the transport and the usage.

The orange color makes this easier to spot against your other tools.

The magnet holds it in place on ferrous metal, so you can read it hands-free.

You can easily read it. The numbers are large, and the needle is easy to see. As an analog tool, it reads to the nearest degree, so it is less precise than a digital gauge.

This product is compact and lightweight, so it fits easily in a toolbox.

Cons:

There were those who find it too big for their needs.

3. Wixey WR300 Type 2 Digital Angle Gauge

One of the easiest angle finders to use is this one from Wixey. Magnets in the base let it stick to a saw blade or cast iron table. Set it on the table, zero it, then place it on the blade to read the bevel angle relative to the table.

According to Wixey's specifications, it has a range of +/- 180 degrees, 0.1-degree resolution, and +/- 0.2-degree accuracy. It runs on one AAA battery, has a backlight, and shuts off automatically to save the battery.

Always unplug the saw before you put a gauge on the blade, as OSHA advises when adjusting or servicing power tools.

Pros:

This is very easy to use, and zeroing it takes seconds.

It reads quickly, and the screen is easy to read.

It is durable for a small electronic tool. Still, remove it from the blade before you start the saw.

It is compact and lightweight. You can store it in your tool kit easily.

It has a good magnet. You can simply hang it on the blade, and it will allow you to input the angle you want to cut.

The backlit display is also a nice feature. It allows users to see the measurements even in low light conditions.

It makes use of an inexpensive battery. You can also find the battery easily, so if you run out of juice, you should have no problems finding a replacement.

Cons:

There were those who wished it came with a 0.0 reference built in the system.
