Devices with more than 20.000 points of logging memory
This page is intended for the power loggers, the power users from the point of view of gathering and saving a large amount of track data. This means you don't want to save your tracks to a computer every day. So you need a device with more than 20.000 points of logging memory. Below is a brief list with the main parameters of devices that can handle this; see GPS reviews for more details on the units listed.
This list was mostly compiled in 2006. Prices will certainly be out of date and device options have changed. Also iOS/android smartphone options tend to be more popular these days (and tend to be pretty massive in terms of memory capacity compared to 2006 consumer GPS)

1 Caution! ─ while the dollar price is cheaper than the UK price, US$ priced units come with a north american basemap, not an european. You may want this, but you may prefer a european unit. And Garmin Germany for example won't repair any non-german units.
