I went to my lfs today to speak with the marine guy and get some advice. He mentioned how I'd need a hydrometer and I explained how I'd read on here that refractomers are far more accurate and does he think they're better as well. He said that hydrometers are quite accurate and would suffice at a fraction of the cost.
He then showed me how the hydrometer works compared to the refractomer and how the hydrometer has large spaces between the marks whereas the refractomer's marks were extremely close together and small, and therefore hard to read.
So now Im confused. How can refractomers be so much better if they're so hard to read? Are hydrometers really that inaccurate? I don't want to spend £50 if £10 will do.. But, saying that, I don't want to spend £10 on something on to regret it and go and spend £50 on a replacement!!
