Small scales for minimal gear set ups are a bit of a pain. Once the Avons disappeared from the market, the only real option was the Waymaster/Reuben Heaton Flyweights. Unfortunately, I regard the Flyweights as one of the worst hunks of junk ever inflicted on anglers. God help anyone that relied on these for any level of accuracy. There must be thousands of folks with PBs significantly under, or over, their true weight.
When I was looking for a small set of scales, I couldn't bear the prospect of paying a fair chunk of cash for second hand Avons. The big RH dials were out due to their size. The scales alone would be nearly as big as the tackle bag I carry on the river. Though I have few fears about the accuracy of the ebay luggage scales, I was concerned by how susceptible they may be to water ingress.
My shortlist came down to the small
(Salter or Salter/Brecknell) Electro Samson and the
RH9000s. The (relative) bulk and high price of the Electro Samsons ruled them out. The plethora of negative chatter about the Reuben Heaton RH9000s almost put me off them. However, on finding a set at a good price, I took the plunge despite the negativity. I found them good enough, small enough and light enough to buy a second set for another tackle bag.
