I've reprinted my comments on the use of my Beta Chrony below; I've also included the URL to the original post.

I also have the "Beta" model Crony, I've had mine for almost three years now and it's functioned for me without problems of any sort. It seems a reasonably accurate piece of equipment, but after reading Matt Norman's post regarding muzzle blast affecting the readings I think some testing of my machine will be the next order business at the range.
The thing I dislike about the Chrony's is that it's got 50 or so functions that are to be preformed with only three buttons. What I'm getting at is that if you don't use a function regularly and don't remember the push button sequence, you had better have the instruction manual handy or you�re out of luck brother! Further, it seems as though the thing has 1500 "error" codes (maybe ten or so really) that again if you've not got the instruction sheet handy, well you get the picture. The long and short of it is, make several copies of the manual and always keep one with your Crony.
I do however like the optional printer that's offered, I picked one up about a year ago, it's a great little add on tool, makes keeping track of an afternoon at the range very easy. What I've taken up doing is to attach the printout of shots fired to the target, make a note about weather conditions, date, rifle used, load data, and so on. Then put it all in a three ring binder for future reference. I find this record keeping method to be very easy to search back through for a particular bullet/cartridge/powder/primer combo that worked well for a particular rifle.

If everyone thought like me, I'd be a damn fool to think any differently!
I like the simplicity of the unit. Along with a tri-pod and pencil and pad, this unit seems to fit the bill for me.
As for the more involved Beta, I decided to go the pencil and pad route.-----Chainsaw
