I'm going to go real old school and suggest the slide rule. While there is a short learning curve, once you've mastered a few simple rules, using one is a breeze and if you keep the slide lubricated and don't abuse it, it will perform it's function reliably and accurately for decades. I have a Pickett, it's now 40 years old but works like new, but just about any brand will offer the same performance.
- dredmorbius 10y agoHow do you lubricate the slide? Metal or plastic?
- sizzzzlerz 10y agoMy ruler is metal and I use graphite to lubricate it. Just take a pencil and run it along the slots and the slide. Lightly wipe it off and then reassemble the pieces. Works great.
