Fully NCEES-Compliant
NLC’s pre-programmed HP35s has all the land surveying applications you need for school, standardized tests, or the field. Each calculator is programmed, updated, and verified so you can begin using it from day one.
Straight from NCEES
NCEES, which administers both the Fundamentals of Surveying and Principles/Practice of Surveying, only allows a limited number of calculators to be used during the exam.
Test takers can either use non-programmed (basic) calculators or use HP33s or HP35s programmable calculators. For a full list of machines, click here.
HP33s and HP35s calculators are allowed to be used because they are programmable, but they (1) have no QWERTY keyboard, (2) cannot communicate with other machines, and (3) have no recording functions.
