You will find that they are probably not "pseudo" caches, but are genuine. But due to the Sponsorship Deal between the NT and Garmin, are solely listed on Garmin's Listing Site. Part of the Deal was the supply of GPSr's for each site, a selection of boxes and Posters advertising Garmin's Listing Site.
The NT loan out the GPSr's so people can go and find their caches.
