I don’t use Bucks, shovels or locaters much, won’t keep or breed a ferret that stays with the kill, haven’t lost more than 4 ferrets in over 45 years and put away more in a year than anyone I know, so must be doing something right. Proof is always in the pudding.
It isn’t rocket science, a big buck will kill more underground and get stuck behind more than a Jill, each to their own but the digging game isn’t really an option here, so you learn fast to avoid it at all costs, yes a buck will kill them fast and move on ( If you keep a line with this trait. I do) trouble with that is they have a tendency to drag them backward into stop ends and get caught behind them sometimes. I have tried both and found the way I do it now seems to be the most time efficient method for this country anyway, thats my two bobs worth a bit different here than UK, wish we had soft ground to ferret and run dogs on.
