Mr. Rawles:
I recently purchased one of these units from Laurus Systems. Upon opening the package, imagine my pleasant surprise to find that this piece of electronic gear was made in Finland, not communist China! While a bit pricey at $375, it is definitely a piece of lab quality gear, but rugged enough for field use. Clean, compact, easy to read LED display. Pocket clip, audible alarm and powered by a standard AAA alkaline battery.
