Sounds more like something from TomTom, meant to give driving
directions for on-road usage...
Even the smallest Garmin eTrex model should handle what you want
https://buy.garmin.com/shop/compare.do?cID=144&compare=compare&compareProduct=6403
500 waypoints; they don't mention how many coordinate systems and datums
are sup****ted. Typically you can toggle the coordinate system after
recording a waypoint in one format to view it in another. You'll also
want to take note of the datum -- native for GPS is WGS-84, but most
USGS topographic maps are still in NAD-27; to use a coordinate from the
GPS you'd want to set the datum to NAD-27 so the numbers match what the
map was referenced against.
My current unit is
https://buy.garmin.com/shop/compare.do?cID=145&compare=compare&compareProduct=351
1000 waypoints/50 routes (digging up my manual as the site doesn't
mention how many points per route -- 50 routes of 250 points each). This
unit is probably more than you are interested in (and 4.5 times the $$$
of the basic eTrex). It even has a parachute "jumpmaster" program in
which you preload expected winds at altitude intervals
(speed/direction), the expected jump altitude, the expected chute open
altitude (HALO freefall jump or immediate chute open HAHO no freefall),
and the landing site -- the program will then indicate where/when you
reach an appropriate jump location to account for wind drift. And silly
games (a virtual "whack-a-mole" where you have to run over something the
size of a football field to get to the "mole" before it disappears). I
have it loaded with the extra$$ US street and Topo maps for California,
Nevada, Oregon, Wa****ngton, and Michigan -- took about 200MB of a 1GB
memory cartridge.

As mentioned, you can change the coordinate units at any time and
see the waypoints in that way.

Don't trust a stream... a few springs of good flooding could move
its channel a few dozen feet <G>
