## Questions & Answers

**Q: What is the maximum distance between the 2 rulers?**
A: I don't have mine here but I'd estimate 2 to 2-1/2".  It really doesn't matter since you can walk the parallel ruler across the chart to a compass rose or wherever.  Check the Power Squadron video at https://www.youtube.com/watch?v=xKSBYfscA80.

**Q: What shape is the product in (the packaging was damaged...is the ruler damaged?)**
A: Are you getting? That is a plotting device aka parallel plotter or ruler,  http://www.weems-plath.com/store/product-list.php?id=20566for Weems and Plath.Good Luck

**Q: What shape is the product in (the packaging was damaged...is the ruler damaged?)**
