I was trained as a machinist, and finding angles always drove me up the wall. For some reason, I find it really hard to trust my own math when creating fixtures with Joe blocks and sine plates, and wind up verifying everything seven ways. Denali has a little something that may take the sting out.

While digital protractors like this have been around for a while, it’s hard to pass up Amazon’s $23 price on this one. Strictly speaking, it may not be accurate enough for precision work, but +/- 1 degree is more than enough for woodworking and sheet metal layout. +/- 1 degree is probably the best you’d get with a steel protractor. More accurate versions are available from Bosch, but ninety percent of the time, Denali’s little 11-incher should be plenty, and it’ll save you a lot of close-up guesswork.

    if this thing has digital capability for the angle, why not also get digital for the level??? this seems like an incomplete product.

    Because digital levels have to be calibrated, level is a matter of relationships, not reason to digitize what does not need to be…..

    I bought one about six months ago and love it. Question –
    How do you remove/replace the battery on this thing? I can’t find the manual and don’t want to scratch it or dent it by forcing the battery compartment.

  4. On the end were the on/off switch is you should see a 4-40 set screw on the back side, remove the screw and pull out the switch assembly you will see the battery.
