This is the most temperamental scale and I don't know how it could be used for fishing as it prefers warm, dry conditions...something that doesn't come to mind for fishing. I purchased it to weigh hay and other feed in the barn. I've had a past version of this scale that worked decently as long as I kept it warm and dry (sometimes difficult in the PNW), but once you changed the batteries, the cheap screws used for the battery cover would mangle, making it impossible to change the batteries again. So when I ordered this new version, I was happy to see the design change to the battery cover fixed that problem.  But now the scale is even more temperamental than before, very slow to register a weight or lack of one, and has trouble maintaining the tare. I am searching or a replacement that is durable enough for daily barn use, accurate, and able to be maintained (battery changing issue...). This is cheap, so I guess that earns it a second star.

Edited Feb 16, 2013...on the second set of batteries already. I thought maybe the scale was being so temperamental due to low batteries, but new ones did not change anything. Loses tare all the time. If you wiggle it while weighing things, it resets. If you hold something up to weigh, you have to hold it up for several seconds to get a final reading...the display goes here and there (up and down in weight) before finally registering something that seems "final". Light works only some of the time and seems random as I can't see the pattern to it. Not at all heavy duty and can't see it functioning for fishing as it has trouble after 15 minutes in a cold, damp (but enclosed, so not wet) barn! I keep it in a heated room and only bring out to weigh hay, and then if it is really cold, have to put it in my inside coat pocket so it stays warm or it really goes haywire. Bad product. Bad. Took away the second star this time as I find it so terribly frustrating to use!
