cheap solution for working professionally with cheap tripod.
I bought this level to use with my DV camcorder (a Canon GL-1). I am an artist who uses video footage in multi-media works. I use a tripod that I've had since the 80's and it isn't equipped with a level. This little 10 dollar device allowed me to get fabulously level footage by sliding it right into the shoe plate on top of the camcorder. A great work-around if you don't have $500 bucks to drop on a manfroto tripod quite yet.
