digital vs naked eye you decide

[Aqua-Digital]

We recently started looking into developing another Aqua Digital product - a hand held digital refractometer using conductivity instead of prism.

The fore and against we see as this

the Fore - easy to read, highly accurate
the against - needs calibrating everytime, although a one touch event.
Peoples built in feeling nothing is better than a refractometer

Ok to pick up on this argument - How many out there really are aware 99% of refractometers are designed to read NACL not NSW? The difference being NACL has no impurities or added minerals that throw out the reading, this is why unless you have a dedicated NSW refractometer, they must be calibrated to a known and trust NSW solution such as pinpoints. Through support we come across a massive amount of lack of education in this.

The concern is how many do not do this and have innacurate salinity readings in their tank? This is the biggest support question we get when clients install expensive salinity probes from GHL and get a different reading, and the reason we are considering the digital approach.

So my question to the community is this - Would you trust a digital reader that can only read what is the correct salinity even if it differs from you old NACL refractometer. Or would we get multiple support argumetns over the reading from what people have learned to accept as correct (when on most cases it is not)

We would love to bring these to market but feel that the hobby is too biased towards what has become standard.

Your feedback is important.
