This 40+ year old compass was my first compass using the Silva System, and at the time Dad gave it to me it was the most basic compass Silva made for the Silva System (but truly all you need since land navigation is a mental skill not truly improved with gadgetry beyond the basics). Today's Silva 1-2-3 is the current equivalent to the old Type 5, and it's really a great compass especially considering you can get one for less than 10 bucks. The biggest thing the 1-2-3 has over the Type 5 is the needle bearing. The needle on the 1-2-3 dampens much more quickly than the needle on the Type 5. Of course neither has a global needle, but there is little sense paying for one if you don't need it.
For orienteering and most land navigation tasks you really don't need anything more expensive or fancy than the simplest Silva System compass and a good topo sheet with a declination diagram.
