Handy Altimeter-Barometer with Compass + Thermometer + Carabiner Clip

Pros: - Alti-/Barometer, Thermometer and a compass in a handy small package. - The Barometer is very accurate. - Very easy to use. - Easy to attach to your pack or belt.

Cons: - Altimeter scale ends at ~5000 meters. - The scale can be difficult to read in low light or bad weather conditions.

Other: Nice, inexpensive device to keep track of your altitude, weather and temperature changes on treks. You'll also have a back-up compass. NOT suitable for skydiving or serious mountaineering. I carry mine for treks and as a quick reference/back-up on mountains.

Pros: - Sturdy design - Feels nice, doesn't feel cheap at all. - Temperature gauge seems working like it should. Not sure whether it is accurate enough. - Carabiner works good and spring is good and tight. - Manual was in English and Chinese.

Cons: - Compass stammers a bit. Not a problem for me, because those compasses aren't accurate enough. I use a good compass for orientation and map reading. The compass on this this is just to give you a hint in which direction you are going.

Other: I would definitely recommend it to any hobby walker/trekker or small time adventurer.

Pros: Very useful little gadget for trekking and climbing. Carabiner is in good quality and it doesn't need any batteries. it shows almost the exact altitude.

Cons: it is easily effected by weather conditions like rain and clouds. compass in the strap is not effective. It is a little slow when you are climbing a hill driving a car.

Other: For an outdoor lover this gadget is just the right one for this price. I wouldn't recommend other battery used types for an outdoor walker.
