The guys recently bought me an electronic fish scale for my birthday gift. Smart eh, buy something that you need for someone else's birthday, isn't that equivalent to buying a gift for yourself?
Anyway, the truth is it really is a great gift.
The electronic scale is around palm size and it weighs up to 22kg/50lbs in increments of 0.01 kg which is 10 grams. This should cover most bases for everyday fishing such as harbour, estuary, in -shore and etc.
With this scale, you could weigh the fish the normal way by attaching the fish to the scale's hook or you could attach a bag or container and zero the scale, allowing for multiple weighing (or when fish friendly containers are used when practising catch and release).
Besides weighing fishes, this scale could be used for setting drags.
