nehunter, There are a number of folks who dwell here that will insist that you must have an Oehler or Mellenium or such. They are the most expensive! Personally, I have been using a Chrony Beta Master (yes, Virginia, one of the folding kind) for years and have NEVER had a problem of any kind. I know of a lot of others who use them too, and the problems with them seem to be no more numerous than with any other brand. I am by no means an expert, but mine has worked very well for me. www.shootingchrony.com
Good luck and good shooting.
