BCB Explorer Button Compass

BCB Explorer Button Compass CK311

Welcome to my gear review of the BCB Explorer Button Compass, I have owned many of these small compasses most of which were included in various mini survival kits and tins that I have purchased over the years. Some of these have worked well but the majority of them have not been great quality or at all accurate.

I have been looking for a new reliable small button compass to carry with me in my Wazoo Survival Cache Belt. So I decided that in order to find a robust reliable replacement it ideally needed to be of military spec. During my research, I came across the BCB Explorer Button Compass which is Nato approved.

Testing The BCB Explorer Button Compass

As mentioned earlier I’ve had a mixed performance from previous mini compasses I’ve owned. so I decided to carry out a test to see how accurate this compass really is.

In order to conduct an accurate test, I compared the reaction and direction of the mini compass with the readings from my Casio G-Shock Master of G Rangeman watch.

I have to say I was quite impressed with the mini oil filed compass. The dial spun freely and when held flat in the palm of my hand its directional readings matched the Rangemans. As a result of this test, I am happy that the BCB Explorer Button Compass would perform well in an emergency situation and get me out of trouble.

The compass performed well when I tested it for accuracy, it’s well-built and costs very little. In my opinion, this small compass is an ideal solution for preppers wanting a backup compass and would make a great addition to your every day carry (EDC). I am confident that it would help me out if I was in a tight spot. Its small enough to go anywhere with you whether in your pocket, survival tin or wallet. It would also make a great addition to a paracord bracelet.

That’s all, for now, I hope you found my review helpful and good luck in your search for a small Button Compass to add to your EDC kit.
