I currently own a 5 and 8" lazer hand auger. I use the 5" mostly when I'm targeting perch/gills/crappies. I was thinking about switching up to a 6" just for the crappies. I've caught some nice size crappies last year. The biggest ones where white crappies. I think if they were black crappies they wouldn't of been able to fit through the hole. I just want to know what your guys/gals thoughts are on using a 6" hole for crappies.
