Description of General Tools 823 Protractor Increments

PREVENT WASTE- This digital 10” stainless-steel ruler and angle finder combination tool makes precise, easy and fast measurements. LOCK IT AND REVERSE IT- Digital protractor has lock and reverse angle functions. Place the angle rule where you need to measure your next cut, LOCK it in place with knurled locking nut, make a mark and use your miter saw to make your cut. The angle finder will automatically display the reverse angle. MEASURE 360-DEGREES- Hinge mechanism on the angle rule allows a full range of 0 to 360-degrees to measure inside outside and reverse angles, accuracy +/-0.3 Degrees. Center check notches are on the ruler ends enables exact ruler placement marking. Display has a hold function to freeze movement for accuracy. PICK YOUR ZERO POINT- Woodworking tool can be zeroed at any point in the swing plus the display can be inverted for easy reading. LARGE LCD DISPLAY- Easy to read LCD display eliminates guessing or eyeballing the angle and length with one convenient protractor tool.

Can be very accurate. The time will show.

Easy to use. Has no switch; turns off automatically. Well how accurate it is. I measured the angle and cut a piece of plywood. Because the size was so large, I had trouble using a real line marker tool accurately, so I did some math and used the tangent function to calculate the second side of the triangle. I cut it out using this line given to me by the angle measured by the tool. At steep angles of 0.53.8°, slight deviations from the vertical result in huge gaps or it doesn't fit at all. My…

Pros
  • Great design
Cons
  • Many functions

It should have been many years ago!

Instead of experimenting with different cuts with my saw or blueprint and halving the angle (and then putting it on the corner fence), I can now use this digital gauge by reading the result divide by 2 and set the angle on my miter saw. As anyone who's done some refinishing knows, there's rarely a true 90 or 45 degree angle in a house (hence heel or toe gap corners and/or extensive use of caulk in painted trim joints). This tool doesn't work magic and your miter saw will need to be adjusted for

Pros
  • LOCK AND RECOVER - The digital protractor has locking and reverse angle functions. Place a square ruler where you want to measure the next cut, SCREW it down with a knurled lock nut, make a mark and use a miter saw to make the cut. The corner finder will automatically show the reversal angle
Cons
  • Slightly torn

Very accurate, repeatable and easy to read

the "straightness" of both scales and the driver's 90-degree square, both were accurate. I used a precisely made Woodpeckers triangle to test 45 degrees and it was accurate too. It's a bit long for checking angles on a miter saw, but it can be made to work. Works well for miter cuts with a table saw. There are many applications for this sensor and so far I am very happy with it. I've found that getting the "knob" at the right angle isn't difficult if you tighten it fairly slowly. It hasn't been

Pros
  • LARGE LCD DISPLAY. The easy-to-read LCD eliminates the need to guess angles and length by eye, with a handy protractor
Cons
  • I'll add later

Great tool with a serious design flaw

This is one of those tools I couldn't believe I lived without. The instrument is well finished with finely engraved markings for the rules. They are very accurate and the angle measurement is accurate to 1/10th of a degree. I would give 5 stars if it had an on/off button. It turns off with a timer. The battery must be pulled out to switch off. battery connection problem. Mine died 8 hours later. I thought maybe the battery in the kit was bad so I put a new one in. It will not work. I ended up…

Pros
  • 360 DEGREE MEASUREMENT. The swivel mechanism on the angle ruler allows you to measure inside and outside angles over the entire range from 0 to 360 degrees with an accuracy of +/-0.3 degrees. There are central control notches at the ends of the ruler, which you can use to mark the position of the ruler precisely. The display has a hold function to accurately capture movement
Cons
  • boring packaging
