LawnBoy If youre concerned about vibration, you might consider a certificated (i.e. TSOd) altimeter. IIRC, the certification process requires that the alt. withstand a certain amount of vibration. These are pricey, though, usually about $300 or more. Might I suggest a wrist altimeter as an alternative. I have a Suunto wristwatch that has the altimeter, baro, compass and time functions. It works surprisingly well and the LCD is large enough to be fairly easily visible. In addition, you can set the sea level pressure on it (essentially the equivalent of setting the local altimeter reading on a Kollsman-equipped alt.) in the event that you dont know the actual altitude of your location. Its also a bit cheaper than a panel-mount and one less thing to clutter up your panel. True, its nice to have the analogue dial. I probably would have put one on my racer if it had an instrument deck. But Ive decided not to install one (to keep it strictly 103-legal among other reasons).
