Cant fault the Salter scales,have used them for 4-5years now.
As long as you look after them and dont let them get wet they will weigh every fish accurately,and as Jim says the buttons could be better.That said,im not sure if they are worth the £80.They could do with more waterproofing
You can get them on ebay for £35 if you`re lucky,at that price they`re worth it....
