Exactly that Will. Digital have a powered digital readout and some sort of silicon chip circuitry/strain guage to do the measuring.
Non- digital usually have a spring of some sort incorporated, attached to a dial or linear scale. Digital tend to be smaller, lighter.
What sort of maximum weight do you want it to be able to measure, Wisker?
Accuracy of spring balance types is usually fairly good, provided the factory has checked them before sale. If treated well the accuracy should remain. Just test the scales with a known weight before purchase. I use a few bags of sugar.
I have no idea how accurate digital scales are: I have two identical ones, and all I can say is that they both give the same reading. Unless you aim to break records, I don't think there is much of a problem to be found with accuracy. In my opinion accuracy is probably "good enough" for most people no matter what you buy.
I have started to have a few chucks for catfish, catching my first ever wels just yesterday, not huge, just scraping into double figures. So in anticipation of improving on that, I am probably going to be looking soon for some digital scales that can cope with greater weights than my current 40 pound set ( no point in aiming low :-) ). I would hate to catch a fish and have to guess how much of its tail is still supported on the ground.
