Weems & Plath Marine Navigation GPS Plotter

The concept is great; but, the quality of construction is not up to what a navigator usually expects from Weems & Plath equipment. Specifically, the arms and hinge points that establish the parallels are flimsy and fail to maintain the parallels required for accurate navigation. I observed a tip to tip variation of up to one eighth of an inch. Good enough for general area but not specific location.

Arrived on time. Product good. Functions as listed. Would buy again.

The unit not only arrived with missing support-feet, but was also slightly twisted.. and WORSED of all, the ruler markings in multiple spots did NOT line up with the holes for the pencil! That is junk and useless! Also, the instructions printed on the back of the plastic sleeve were so faded in half of it that they were unreadable... again a lousy job! The main fault here lies with the manufacturer Weems & Plath, as the quality of their packaging and the misaligned markers printed on the ruler are totally on their Q&A department! I ordered another one, but if this one comes out the same, I will have to have a word with the company (or AMAZON should before they accept the product and put it on their shelves to then sell it!)

As expected it was delivered when promised. I have been pleasantly surprised to find how easy it is to use, especially on the smaller folio charts. It is the right size for my navigation bag,so it will be used as often ashore, route planning, as on my yacht. One criticism; it could be cheaper!

This tool makes plotting and navigation easy. well packed and on time.

Very good, works well and is easy to use.
