## Questions & Answers

**Q: Is the cm is displayed?**
A: Hello! Unfortunately just inches are displayed.

**Q: For taking basic nav course, could this be used instead of the standard par. rulers/divider/prot? iow, could i take base course using this? thanks**
A: I would use this as an adjunct. You need to know how to use parallel ruler, dividers etc on a map for the navigation course.

**Q: What is the maximum distance between the 2 rulers, commonly called the opening width? Thanks!**
A: Hi Caroline, this ruler does not open up, it is a rolling type of plotter. Regards Mark

## Customer Reviews

### ⭐⭐⭐⭐⭐ Nice
*by M***. on December 30, 2025*

Not used it yet

### ⭐⭐⭐⭐⭐ Very high quality
*by M***. on July 13, 2021*

This is handy when plotting your courses.

### ⭐⭐⭐⭐⭐ It Works
*by K***M on May 14, 2018*

Works good. Made out of 1/8" sturdy plastic (probably won't take bending at all). Wheels seem to grip plotting and chart paper reasonably well. It is about 12.5 inches long so you need a bit of room to use it - especially to keep the wheels on a level, gripping surface. It will go in my chart kit and out to sea.
