The ikan Tablet Production Slate, a.k.a. the T-Slate, is designed to perfectly integrate with the MovieSlate app. via an iPad, but it can certainly also be used standalone, at the employ of a marker like in the old days. The clapboard is white acrylic with engraved lines and titles, and the clapper is made of durable wood and drops with a loud and crisp clapping sound.
But ideal use would be with an iPad and MovieSlate. MovieSlate's built-in clap detection function can detect T-Slate's clap by measuring a combination of sound and vibration.
Setup requires an iPad case and is simple. Slide the case into a slot and secure it with a waistband. A waistband isn't included but most any kind can be used. And most iPad cases can be used except for magnetic ones such as Apple's Smart Cover.
