In this case, common in the eastern US, the 24K map shows 40’ contour intervals vs. In the images below, a 100K scale Garmin map is shown at top, with TOPO US 24K below it. The TOPO US 24K maps give you greater detail, with more closely spaced contours.

Sure, you won’t hear audible directions, but you don’t have to transfer waypoints to a second device (like a nuvi) just to navigate to the trailhead. This means that if you have a waypoint for a trailhead, you can mount the GPS receiver on your dash and get turn-by-turn directions on compatible Garmin handhelds (as shown at right). The other is that these roads are routable. TOPO US 24K maps use the more accurate NAVTEQ road data however, just like Garmin nuvis. People look at their unit and think it’s a GPS accuracy issue, but it’s just that the road is misplaced on the map. Garmin’s 1:100,000 scale topo products utilize TIGER data for roads, which are almost invariably off from the road’s true location. Strangely enough for a topo product, this is one of the best reasons to buy TOPO US 24K.
