Review: At less than half the cost of the Weems and Plath item, I wasn’t expecting much. Man was I surprised! This is every bit as good as any other TSD calculator out there. I’m a full time live aboard cruiser going from Maine to the Bahamas every year so my tools get lots of use. I’m not going to have to replace this.
