I was wondering if Silva has made all of there models adjusted for magnetic dip through the 5 zones of is it just the Silva Voyager series. (see below article)

It's all in what you prefer I guess, I used the Cammenga in the military and it's been in Alaska to the Philippines and has been rock steady, but it is heavy and you could probably throw it at some body and put an eye out. I guess there are some things that we get use to and it's hard to part with but it's been a good little compass for me and I haven't got any needle sticking while traveling. I'll stay with ole faithful for me but it sounds like Silva may be it for you guys, just get one that will work in all 5 zones like the voyager series for example or a Suunto M-2G.


Geographic Magnetic Zones & Dip
The horizontal and vertical components of the earth's magnetic field vary considerably at different
locations on the Earth. This causes the compass needle to point down vertically into the Earth at
the magnetic poles – while the needle stays horizontal near the equator. This vertical magnetic
component is called Inclination or Dip.
To get an accurate reading from a compass, the needle or dial card needs to be ‘balanced’, so it does not drag on the top or bottom of the capsule. Because of the variations of the Earth's
magnetic field, a compass needle that ‘balances’ perfectly in North America will drag or stick in
South America. To accommodate for these magnetic variances, the compass industry has divided
the Earth into 5 Zones:
Compass Magnetic Zones
Zone 1: MN – (Magnetic North)
Zone 2: NME – (North Magnetic Equatorial)
Zone 3: ME – (Magnetic Equatorial)
Zone 4: SME – (South Magnetic Equatorial)
Zone 5: MS – (Magnetic South )

Most compasses are compensated for magnetic Inclination or Dip across these Zones by a
counterweight on one end of the needle. This keeps the needle level and prevents it from dragging
on the top or bottom of the capsule. Some compass manufacturers, Silva and Suunto for example,
offer normal models that are set for specific Zones – and ‘Global Dip-corrected’ compasses that
will operate just about anywhere.
Being a military specified piece of equipment, Cammenga Lensatic compasses are designed to
function anywhere in the world. Most of the compasses they manufacture are balanced for Zone 1
– but even these have been tested and used successfully even in Zone 5 by holding the compass
at a slight angle. However, Cammenga do supply models balanced specifically for the Southern
Hemisphere.


Added note: I added the bold letters so you could just read the highlights of the boringly long paragraph, I didn't want to think I was yelling or anything, I just wanted to make the point if your going to invest in a compass and plan on traveling out of country that it may be beneficial to get one that will work through the 5 zones.
