At the very least, there should be a larger viewing area where you can line up the two points on a station and see them directly against the measurement.
And we need a better way to light the darn things. Maybe some really hard transparent plastic shell rather than metal.
Anybody want to engineer a new compass??

PS: many of the same things go for clinometers

Secondly, the size of the numbers have, I've noticed, increasingly become a problem with older cavers. Their eyes arent what they used to be
Thirdly, the light situation is a problem which is a symptom of using terrestrial surveying tools for subterranean surveys.
Like I said, it's not a terrible design, more of a mediocre one. But would you pay $200- for a mediocre light source? We pay that for the suuntos becuse there really isn't anything else out on the market. The dowside is that there probably aren't enough surveyors to make making your own equipment worthwhile. Of course, one of the reasons people don't like to survey is that its such a pain in the butt.
