Ultra Sonic Range Finder Review


I’ll be the first to admit that having a job as a hardware reviewer isn’t exactly a bad lot. We get to check out some of the latest pieces of kit around, and occasionally when we’re done we get to hang on to them. This of course has no impact on what score we give an item when reviewing it; but it does occasionally give rise to random items being reviewed.

Being totally honest, today’s review is of one such item. It’s a laser and ultrasonic range finder from our pals at EFO; here’s the review.
