4000 vs 4500 are 4 years apart December 14, 2008
HMMWV (santa clara, CA USA)
I bought my 4000 about 4 years ago - since then they may have updated the firmware but it had one nasty bug. If you wanted a continuous plot over time (days lets say) you had to leave the 4000 turned on continuously to gather data. That meant batteries - LOTS of batteries, even though it ran for 3 days on 2 ea AAA cells. It also meant alot of use of the battery door, which has a firm gasket to weatherproof the unit.
In short, the battery door proved to be a weakness - I had an OD and a bright orange unit - both failed on the battery door. Due to the glued up housing design the broken part made the units unrepairable.
Today the 4500 model is available for $35 more and includes many more features, like a compass, and the ability to have the unit power up, take readings, and power down every 30 minutes. So far after 10 days, mine has only used 3% of the batteries taking measurements every 30 minutes for detailed plots of pressure, altimeter, wind speed, and a half dozen other variables.
The 4500 represents the state of the art system which is why I purchased it after destroying two 4000's. You can find the 4500 here:
Kestrel 4500 Pocket Weather Tracker. They also make an OD green version, however the backlight is optimized for night vision goggles which means ordinary eyesight won't see much at all. Unless you are using it with a $4K set of an/pvs-xx goggles then you should buy the yellow cased version which has ample brightness for night use.
