I'm not sure what you mean by a "more precise instrument", JB. I don't think that measuring SPL in db is particularly esoteric technology anymore.

Tom, if you have an iPhone or an Android device, you might be able to find a (free) app that does basically the same thing. I mean, we're not trying to launch the space shuttle here, or anything.

I'm not familiar with the Scosche. Mine is an old RS analog type. I suspect the chip in all those devices is probably the same. Looks like our Canadian brothers tend to have to pay more for this (among other things) than we do south of the border.
