Background
My name is André Boisvert, I'm based in Montréal, and I'm working on my 21st year of production sound, almost exclusively single system.
In the mid-90's, I started using a cardboard slate with stick-on letters and Velcro to identify my tracks for post. Problem was that stick-on letters become stick-off letters after awhile and cardboard isn't very weather resistant, or production resistant for that matter. In 2007, I started working on a slate that would withstand both. This is the result. Made of tough ABS plastic, Velcro, and weather resistant labels, I think it'll outlast most of my gear.
Marketing
By having your name - or your name and phone number - on your slate, the Single System Slate is also a no-effort marketing tool. I've met editors who knew my name because of my slate. Granted, I've never had a job from an editor, but getting your name out so effortlessly can't be a bad thing.
