I've posted on this before. All versions of the digitial scales will work for awhile and are accurate with fresh batteries. However I have killed them all but weigh literallyt 1,000's of fish spring-fall. I still use a digitial but only on fish bigger than 5 lbs. I have for the past year used a kitchen scale from Walmart. It is accurate to 1/8 ounce so great on small fish up to 5 lbs. At $35 I can afford to replace them often compared to soem of the hihger end flat scaels offered in aquatic catalogs.
