Just what I was looking for to set up my home theater reference levels. I also calibrated my brother's setup. Here are all the important factors you need to set up your home theater - weighted, slow and different areas. I love that it also has a tripod mount (remember to set it up so it's pointing straight up). It would have been nice if a carrying case was included, but that's not a big deal considering how durable the plastic feels and there's a foam windscreen to protect the mic. One suggestion for future versions would be to be able to input a desired decibel level into the device and then have a beep or indicator light when it's reached. This would be very useful when calibrating subwoofers, for example, where the volume on the subwoofer might need to be manually adjusted while leaving the meter in the main location. exhaust, how loud my roar is and the difference the baffle makes to my motorcycle exhaust.
