For garden or agricultural purposes why would you need
accuracy down to decimal points of a pH unit?

One decimal point my be important, as soil pH changes in rather small
range - and the difference between 6.5 and 7.5 is rather important,
while every soil in this range will be measured as just 7 (perfectly
neutral) without any decimal digits. But IMHO you don't need the pH
meter in a garden, for most cases pH stripes will be enough.

Seems fair. Such would probably be cheaper and easier to use too.
