What to know before buying

Listing details to confirm

Listing details conflict on scales: the title and map-scale field give 1:25k, 1:40k and 1:50k, while a feature description also lists 1:24k. It also describes the model as having GPS functionality without explaining that claim. Confirm the scale markings and intended GPS meaning before purchase. The four-hour illumination claim is conditional on activating the markings in light.
