I purchased the Helix with the idea that the thermometer and barometer would give me some rudimentary short-term weather forcasting tools. The problem is that I'm not sure I trust it beyond: "hmm, seems to be getting colder out here," which I really don't need a thermometer for anyway. One of these days I'm going to check them against some I know to be accurate. If they come up reasonably close then they could prove useful.
