it could work very well and a single excel spreadsheet will keep track of everything, however the scanners are expensive. but, so is mixing up 10k worth of hets. i've used the scanners at a previous job tracking micro chipped fish stocked in a area lake.
Oh, neat. That's exactly what I'd like to do. Why kind of chips and scanners (ie. what brand), and where did you get them from, do you remember?
