Just use my phone with NZTopo 50s on it and have topo maps on my Garmin Epix watch also. Mainly use the phone to have a look and make plans etc while at camp and then just use watch on the hill. I usually have a pretty good idea where I am anyhow but always mark camp on my watch, works good, saved @Philipo and I when we were stumbling around on the tops in the fog would never have found camp again that evening without it
