silva expedition compass 4, 21 September 2016

excellent product for DofE Expeditions
not as good as they used to be, 10 April 2016

I have had one of these since the 90,s and it was great. How ever I decided to purchase the new version with the 1-40 scale for my BMC maps. The first time I used it I noticed a bubble appear as I hit around the 800m mark. Now (a year on) it happens at around 500m and if I hit the altitude 800 or above I get 2 or 3 bubbles that turn into one huge bubble. Silva would not entertain the warranty.
Appalling Quality, 23 February 2014
By TreeMadDog (Staffordshire)
I'm 52 always used Silva compasses but today believe Silva are merely trading on their name and former Swedish heritage. compass is no longer marked as 'Made in Sweden', and the quality is dreadful. The compass I purchased had >2 degree error in baseline markings, when N mark on the bezel was aligned with index mark on the housing it had base grid lines which were visibly aligned 2 Deg to west of the base plate lines - serious potentially dangerous built in error. Returned to Silva for warranty replacement, which they duly did but second one still has an error in base lines ~1 deg west of base plate lines. An appalling lack of quality control! Looks like I will have to give Suunto a try.
Excellent piece of kit, 03 October 2013

The Expedition 4 is quite frankly the best on the market. It has everything you need short of military grade.
As for the review below, the compass has quite clearly depolarised- probably from being near your keys or mobile phone. You can post it back to Silva and they sort it for free.

Please ignore the first review. Assuming the review knows how to use a compass and it was reading 180 out, I assume it had been demagnetised, which can happen to any compass. Quite frankly it's the only compass taking out on the hill. It's the compass all others are measured by. Buy it and learn how to use it.
