View Full Version : Magnetic Protractor vs. Digital Angle Finder?

Our local Chinese import tool ***** has two different angle measuring devices on sale right now. One, the magnetic protractor, I've used before and they seem to be OK. The other, the Digital Angle Finder, is something new that I haven't seen before.

Has anybody tried one of these and, if so, are they useful enough and accurate/reliable to be worth the extra money?

Any comments from someone who's got one?

I have this digital angle finder:

Absolutely love it -- measures up to 359.99 degrees. It has come in handy more times than I can remember -- HIGHLY recommended. Like it better than the one you show because it is smaller and can go in more locations. A really useful cool device.

The small square one finds the angle but assumes that the item that you are referencing is level. I guess you could work around that by measuring both pieces then subtracting as necessary.

No I have not worked with either one.

I do have the plastic needle angle finder and don't like it much. It seems the needle doesn't move freely enough so it sticks at not the exact angle.

Not true -- you can zero the degrees at any point. Let's say you wanted to find the angle between two things but they were not level;
1. Put digital angle finder on piece one -- press the zero button
2. Put digital angle finder on piece two -- the readout will show you the angle in degrees.
Done deal -- easy peasy

I tried the protactor and will be in the market for a digital.
With my luck with angles I need all the help I can get!

Hey **** ***, you just reminded me: I bought one of these when they were on sale from Lee Valley Tools

I'd forgotten all about it until now. Doh! :rolleyes4: Is it senility, or just bad meds, LOL?

Harbour Freight don't operate in Canada & that's a darn good price.

However, I've been reminded that I purchased one of the "box" type electronic angle finders from Lee Valley Tools the last time they were on sale. I had forgotten all about it. [Don't even ask how I came to forget about it....]

So I guess I needn't buy a plastic protractor, and will keep my eye out for the "scissors" type of electronic ones. If Harbour Freight are selling them for $25 stateside, some store in Canada will get some in at under $30, I'll bet.

P.S. after a quick look 'round:

Not precisely the same item, but close enough for Zombie Werkx.
Thanks very much for the feedback, David. I feel better now. :jester:

Trike Lover before getting that one read the others comments about the small square electronic one. I was incorrect in some of my comments about it. You can zero it out on one piece then measure the joining piece. I think I might prefer that one as it will fit in tighter places.

I had the Starrett version of the right-hand end of the tool in your first picture. Then some turkeys broke into my shop and made off with that any my Mitotoyo caliper. Hanging's too good for them.....

Thanks, David. As it turns out, I already have one of the small square electronic ones. I bought it on sale a while back, and then forgot that I had it.

Just losing too many brain cells....
