I previously had an Ainsworth pocket transit and found my Brunton to be much more reliable and sturdy. The Ainsworth needle would get stuck due to the design of the copper coil and wasn't waterproof (even by itself in an airplane cargo hold). I haven't had that problem with the hanging design of the needle. The workings and features are much more fluid than those of the Ainsworth. I was also impressed that for the price, the housing was metal and not plastic as I've seen.
Pros: Sturdy, quality craftsmanship
