I think this would be more of a DIY tool lol. Pretty much all those functions are things your average carpenter already does just as quick with a tape and speedsquare.
But a cool find for DIY projects nonetheless.
Its got some nice features. Sure you can do most of it without it so it won't justify a high price but it will make it easier, so would still be nice to have.
I remember seeing a video like this in high school last year...great tool, can't believe I forgot about it...whoever designed it is a millionaire by now
