The tube inside is made of glass :/

I purchased mine for my Winter Mountain Leader assessment and it had a small bubble in it which stalled the ball bearing for a few seconds every time it had to enter/leave the bubble. I phone facewest up and they said all of them had bubbles. Over the last year the bubble got bigger and more annoying until rest of the liquid has disappeared so the ball is no longer damped and moves around rapidly. Being well out of the returns period I dismantled it. The tube inside is glass and it has a tiny crack where one end is glued into the base. I had expected plastic. Hardly back country proof, I'm less than impressed.

Handy little slope meter.Light, small, easily fits in a pocket, simple to use and read.Useful for developing judgement on slope angles for avalanche awareness - shows that eyeballing angles can be significantly off actual angles.Good to use in conjunction with checking slope angles and route planning on a topo map or website (e.g. Avanet has a slope angle overlay).

The inclinometer was bought for a recent avalanche course and preformed well in measuring slope angles.It was mostly used when doing a snow profile when static and using other pieces of kit.In hindsight, I would have purchased an inclinometer that remains fixed to my ski pole so I could measure slope angles on the move much easier.

The compass did not appear to be too reliable and I would not rely on this alone.

I was looking for an inclinometer and a few friends have the, Pieps digital one that fits on a pole, the BCA one is very compact and is easily stored in a jacket pocket and has a great little hole that's big enough for your thumb and forefinger to fit in. Easy to read with the ball bearing as a measure and in a lot better than using your iphone. Great piece of kit.

The Slope Meter measures slopes to a reasonable accuracy (+/- 2 degrees), much better than the estimating angles from ski poles. It fits easily into a pocket and will not break should you land on it when falling off piste. The red/ orange markings are a useful reminder of the most dangerous slope angles. It should be noted that a bubble within the glass tube can prevent the black pointer from moving, this is easily rectified by holding the instrument vertical. This is a useful piece of kit for ski touring. Buying the Slope Meter, Crystal Card and Temperature probe was cheaper than buying the snow study kit.

This was purchased after a 4 minute argument with a vastly more qualified mountain guide, stupid me! I used the old and bold two ski pole method of guessing a slopes angle and getting it wrong by 9 degrees! Gulp. The Bergfuhrer then produced one of these from his pocket and proceeded to belittle me in the fatherly way they do.

Feather-weight, very accurate and nigh-on indestructible. I was a little peeved that my wife told me she had one of them on her iTouch which is a free application, but £30 and bomb proof beats £200 and fragile every day. Oh and on a personal note always listen to your mountain guide!!
