Starrett ProSite Miter Protractor Angle Finder with Two Laser Engraved Scales - Ideal for Carpenters, Plumbers, and DIY Home Improvement - 12 Aluminum - 505A-12

Dont order it on the internet....go to the tool store with your speed square. 1st 1 I checked was out a 1/2 degree, 2nd 1 was on the money.

Yeah, roll your curser over the picture on the product page for this protractor. Dont the numbers and lines look like so many precision Starrett tools? Not so. You get stickers! $70 for stickers? This is a $30 tool at most. I cant say this tool is worthless. Its just not the precision $70 tool you think youre getting. Good for trim around the house, but not for accurate wood working, IMHO.

Starrett continues to make durable and practical tools. The ProSite Miter Saw Protractor is an accurate measuring devise in a compact size for efficient use and easy handling. This is a very cost effective measuring tool saving booth time and materials by reducing the likelihood of mistakes.

I bought this as soon as it came out, last fall. It is wonderful. I use it often, in the shop and on the road. It is unmarked, undamaged. It can be hard to read the dial, but I am getting older. It holds an angle as you carry it around without a care. Treat it with care, own it for life.

Great tool to assist with crown molding and many other types of work. I do welding projects also and have used this to find the angles to cut square tubing and angle iron.

After receiving 2 of these items, both with the same problem, I opted for the new 7 inch version. The problem with both units of the 505A-12 was that they were not even close to being true with their own calibration marks. I believe that 2 degrees or more are definitely out of spec for any measuring device, especially one that carries the Starrett brand name. I almost think that this type of accuracy would even be out of line for items coming from Harbor Freight! Amszon would not send out a third, so I had no choice but to go with the 7 inch version - which did not have any of the calibration issues of the 12 inch version. Im glad I was not needing one of these for an immediate job...

Works great with wood working but costs way too much.

Unlike some of the reviews posted here have indicated, my prosite was dead on accurate when I measured it against my speed square. On the other hand, I trimmed a whole house and never really needed it. I just used a $6 bevel guage on the corners that were visiblely out of square. It might be more useful for crown, but for base and casings it just wasnt necessary.

This tool made cutting meters and angles so much easier to figure out.

I am a DIYer and have been looking for an inexpensive tool that will help with determining various angles for installing modeling and building various projects that are not always at 90 or 45 degree. I couldnt justify to myself to buy a digital version that for a reliable one typically starts at well over 100$. I came across the Starrett and know what it is a good name brand so figure I would give it a try. This is worth every penny. I recently used it to put up a built in bookshelf on a kick wall in a finished attic. The wall is at an angle so needed to determine the slope of the wall in order to build a level bookshelf. I used the tool to determine the cuts. It worked perfectly. I put the tool along the wall to determine the angle I need to cut to make a level shelf against a slated wall. I was able to determine all the cuts using this tool and never once had to calculate an angle I used to the tool for everything!!! Since then I have put in some baseboard model in an odd shaped room the tool helped tremendously with making accurate cuts to create tight joints. I would consider buying the smaller version too! Which I recently did.
