What she said. I'm on my 4th SK7. Next I'll probably give the FS-1 a spin and see if it lasts any longer.My understanding is that there is no compass more talerant of tilt than the SK-7. The problem with them is that they don't last very long -- eventually the plastic develops some kind of micro-cracking, the compass loses fluid and sticks. Home repairs aren't very easy or successful, and the modules are $70 apiece, which is kind of expensive if you are replacing them every couple of years.
