In aviation there is a device (analog circle-within-a-circle calculator), the E-6B, which was and still is used by pilots to solve many different problems in aerial navigation, fuel use, pressure altitude, density altitude, etc. I have begun to eschew electronic devices in favor of tools which don't need batteries. I still use them as a "backup." LOL
Is there a nautical slide rule or E-6B-ish tool available? I have tried to find one myself, but without success.
