## 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

### ⭐⭐⭐⭐⭐ Not bad
*by J***E on May 25, 2023*

Works as intended but quality not the best. Plastic can warp easily.

### ⭐⭐⭐⭐⭐ Zoom! Zoom! Zoom!
*by J***. on June 22, 2019*

These devices are used in plotting navigation courses and in this particular instance, the constantly evolving waters in the Gulf of Mexico. A parallel ruler is rather old-school and funky in comparison to these doo-hickies. EZ to order coupled with lightning-fast processing and delivery. Happy Camper!

### ⭐⭐⭐⭐⭐ 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.
