How to use Forums
Our forums on Land Surveyors United are here to be used as much for finding help with problems in the field as the are for you to express your opinions on anything that has to do with land surveying in general. Feel free to share anything that is on your mind, as long as it isn't meant to damage another member's reputation. Please keep it clean and help insure that everyone has the opportunity to enjoy the benefits of being part of a community that grows together.
We are committed to allowing freedom of expression for all of our members, and that includes maintaining a safe space for people with opposing views to express themselves. We get posts from all over the country and even the globe, so needless to say, people come with different viewpoints on lad surveying practices and processes. We see this diversity and variety as a real strength-- dialogue and debate are an integral part of the educational process, as well as an important tool in exploring different sides of complex issues.

Community Hubs inside the community have their own forum for asking specific questions to other surveyors, by location, equipment type, etc.

I don't know how it ranks with the others as the one I have (D'Zign) is the only one I have experience with. The HP 50 is a scientific calculator made for folks that work with higher math. It takes some getting use to. It is harder to use than the HP 41 due to a more sophisticated & more complicated operating system but if you can navigate a HP 48, I would think a 50 will work about the same. If I am not mistaken, the HP 50 is just an upgraded HP 48. My memory is a little fuzzy on the evolution of the HP calculators. Wasn't the 48 followed by the 49 & then the 50? Maybe some of the other programs are more user friendly. What aggravates me is if you are not in the right "mode" doing ordinary survey math, you will get a math expression instead of a number, ie: answer. I used my 41 until it died then went to the 50. It does work directly with degrees minutes & seconds without the need to convert back & forth to decimal equivalents.
