Never heard of it, so I did a search and found the youtube vid
it looks OK, but its just an electric scaler that will do a faster job than a hand scaler? doesnt seem to have any other advantages. Still, Id buy one just cos I like gizmos.
my problem is that I have no scaling facilities at home, now that Ive moved into a small unit, so I have to fillet in the boat, and I dont want scales flying everywhere. A tub isnt gonna fit on a 4.1m boat ha ha.
