Excellent sighting compass. Just be careful using the sighting system when wearing spectacles
By Waypoint Charlie
A while ago I bought the Silva Expedition 4 but then rather regretted not paying the (not insignificant) extra for the Expedition 54 with sighting system. When I lost the Expedition 4 (the tide came in a lot faster than expected) it gave me the justification I needed to buy the Expedition 54.The simplicity and accuracy of the sighting system make it an absolute delight to use. As the previous reviewer commented, a GPS is no substitute for a good compass. My Garmin GPS is good for telling me where I am, how far I've walked, for how long etc. However, I still want a compass for map reading, accurately sighting my next waypoint and for identifying landmarks.Elsewhere I saw a comment from a user who was perplexed as to why they noticed a discrepancy of several degrees between bearings taken using the conventional baseplate and those taken using the sighting system. I sometimes noticed the same thing, until I realised that when using the sighting system my steel framed sunglasses were causing a deviation - rather obvious with hindsight. Most spectacles probably contain some steel parts (eg arm screws) so be careful if, like me, you're a permanent spectacle wearer. In future I'll try to ensure I buy spectacles that are magnetically inert, although I suspect Specsavers will be a bit bemused to see me running my compass over their latest designer frames.For maps with a wide grid (eg 4cm with OS Explorer series) the sighting mirror in the housing can be a bit of an irritation because it obscures some of the orienting lines. This is one disadvantage over the Explorer 4 compass, but you get used to it.Like the Explorer 4 the paint is phosphorescent. For night use I'd have preferred it to be radioluminescent tritium. I believe it is still possible to obtain the tritium '54B' version.The compass card is graduated in 1 degree intervals but the housing is graduated in 2 degree intervals. When tired you have to be careful to remember this when moving between map reading using the housing and sightings using the compass card.Unfortunately the Expedition 54 costs getting on for three times that of the Expedition 4 compass, probably making it an expensive luxury for many people. However, it's worth paying the price for good tools. Just be sure not to leave it on the beach!

Great little instrument.
By E. Hulme
I had been using a smaller Silva compass for a few years and decided to upgrade to the Expedition 54. I should have done it years ago.The extra length of this product made it so much easier to align it with the grid lines on the map and the addition of a prismatic facilityhas made following a bearing so much easier and more accurate. Coupled with a cheap, six inch plastic ruler, this compass has transformed mynavigating skills. GET ONE NOW!As for Amazon's speed of delivery, no need at all to change that.Eric Hulme.
