5.0 out of 5 stars Good product with some annoyances, February 22, 2009

This model was released in 2003 and Amazon started giving it away for under $100 recently. For that price, it does everything you expect it to do. The menu system is simple but takes a bit getting used to. The contours are like a continuous mathematical function without surprises or sharp edges and the extra clip on lanyard is quite good too.

I use a Garmin 60CSx and compared its altimeter to Brunton ADC Pro's. My calibration was at a shipyard: set both devices to measure 1M above sea level, and stayed there to see how they report after some time.

The Garmin altimeter jumped as much at +/- 5 meters within 2 minutes while the ADC continued reporting 1M, and sometimes 2M for few seconds. Then I continued walking to a spot of different elevation, known to be 12M. The Garmin totally flipped out and the error difference increased to +8M, while ADC reported the altitude correctly (12-13M). The first unit I purchased was out of control when altitude was concerned, Amazon shipped a new one that seems very accurate.

(Update June 24, 2009). The second Brunton sent by Amazon was accurate but its Reset button died out when DST change occurred. After returning it again I finally got one that seems to work properly (nice people at Amazon). On the date/time issue there might be another minor bug undiscovered by me: the data logging seems to suggest that ADC is programmed with 2003's DST settings which might not be accurate anymore.

Brunton forgets to mention that its impeller is magnetic and one of its blades is painted red to identify magnetic north (for use as a compass). It seems that ADC measures wind speed by the current generated when the fan blades move i.e. their logic is: measure how fast the magnetic flux is changing and translate that into wind speed. The coil is most likely enclosed in the plastic tube that surrounds the impeller. I'm not sure if they're using rare earth magnets for this purpose, but upon losing their strength, the impeller can start reporting lower wind speeds.

Another gripe. If you happen to change the batteries or reset the ADC, you'll have to leave it in the same place for 12 hours so it can accurately understand our current altitude.

A small button (upper right corner of the controls) turns the backlight on: a timid green that disappears after 3 seconds.

4.0 out of 5 stars Not Bad, September 6, 2008

I bought this mainly for the barometer and anemomter features to have along for fishing and hunting trips. Both of these features work very well, as well as the hygrometer. The unit shows these in real time, tracks changes and records minimum and maximum events.

The only feature that doesn't work well is the altimeter. I don't know what theory or system is used but it isn't accurate, at least not on my unit. I can be sitting in the same place and watch the altitude go up and down without moving it. It's very seldom that it remains stable. I can understand some fluctuation +/- a couple of feet but it goes beyond that. Since the altimeter wasn't an important feature for me it's not a bother.

The unit seems to be made well and hopefully proves to be reasonably durable, which I think it will. It's a bit pricey but I got a better deal on Amazon than I found anywhere else. All in all it's not a bad little unit.

It does everything I need it to do.

I use it to collect data during test periods, and while it's not highly accurate (i.e. you can't get it NIST certified), it does what I need it to do. I then use the USB/infrared port data connector to download the data from the device to my laptop.

I also monitor temperature and pressure while on air flights and in conference rooms. It helps when instead of saying "I'm cold" you can say "can we turn down the AC: it's 65F in here!"

It's great on hikes - monitor elevation gain as well as temperature and wind speeds. The built in compass is small, but it works. So should help if you get lost, too.

One downside - the temperature response is slow. You need to leave it in an area for at least 10 minutes to get a real temperature reading. But, you can watch the built in trends to see if you've leveled out yet, too, which is helpful.
