Good to hear your views. As for the digitals, I think you'll find the higher poundages they weigh (ie. 50 lb scale compared to a 10 lb scale) the higher of a chance to be out. I don't fish for musky or salmon anymore, so only carry a 10lb scale. For the last 7 years, it has weighed precise. This year it was off 1.6oz. The only downside to spring scales, is for the most part, they only measure in either 1/4 or 1/2 lb increments. Great for 30+ salmon, not so accurate if you want to know if you broke the 6lb mark with a largie or smallie. (Now, I'm sure the higher end spring scales may show ounces, but I'm not 100% on that..)
I'm presently working on an article for OOD (due out in March) that will showcase all of the scales currently available in Ontario. I will be showing their merits and downfalls, and will be spending some time on the water with most. It will be interesting to see the differences in spring versus digital, and also the new models that are currently out. Berkley has a new model coming out for 2007 that looks pretty sweet~!

Good Fishing,
Justin
