Polymath ProductsCMP-20 Compass Necklace. Rugged and reliable navigation aid with precision luminous dial. UK-made.

While I certainly won't be using this compass as my main navigator, it is a brilliant emergency backup, or something to use for frequent bearing checks. Rather than being a cheap, poor quality novelty, this little CMP-20 Compass Necklace is actually a well-made, quality little instrument. The dial is surprisingly easy to read, given it's tiny dimensions. The fluid-damped dial spins freely, and is very accurate. The luminous paint works very well and you could definitely read this compass at night. It's not going to replace my Silva 4 Militaire. But it is a worthy addition to any backpack, or just to wear on a day in the countryside as a 'just-in-case'. Recommended.

It's small, it's portable and it's accurate. Perfect for hiking.It looks and feels vintage, in a good way.It's really sturdy (I accidentally stood on mine and it's still perfect).Best of all it doubles as a Santa detector (to distract small screaming children on public transport)A++

I didn't expect much other than I can use it for work, not easily lose it and it'll help me orientate myself when surveying trees within dense woodland. It seems well-built for its price and works well considering its size. It'll do the job nicely and should last a decent amount of time. It would never be something I'd rely on to get me from A to B or home/safe. But it'll work well for what I need it for.

Very good product and service

It's quite remarkable how something as small as this compass, built to military standards, can be so accurate and rugged and only cost £7.99It has to be said that if its neck cord is broken, then the compass may have to be either replaced, or its cord tied. It is fluid-damped as all high quality compasses are manufactured and utterly reliable. Weight around the neck is negligible.It would make a great present to a teenager or a young boy who enjoys camping. I love quality and this reliable little compass has it in spades. Made in the UK.

It’s quite difficult to find a small compass that actually works. The Suunto Clipper I purchased for three times the price failed almost instantly. I purchased two of these and they work flawlessly. Nice military styling. Good to buy British also! 🇬🇧 My only comment is that the cord, which disappears inside the body of the compass, should have a breakaway safety clip, particularly if you are going to buy it for a child. It’s easy enough to buy one and fit it though.

Good price but is a little too small.

We bought this for our grandson, aged eight, and he was fascinated by it. It's easy to read, small, with a neck string that's comfortable to wear, and the dark green surround protects it from youthful enthusiasm. Very good value.
