Altimeter Professional Aluminum Accurate Clinometer Waterproof Optic Height Clinometer Battery-Free Compact Portable Handheld Clinometer Forestry Outdoor for Height & Slopes Angles Measuring

It did as expected

This is a cheap knockoff of a Suunto clinimeter. I bought this as a necessary replacement for my Suunto Tandem Compass/Clinometer, which I put somewhere where I would be able to find it. This is not an altimeter as the description calls it. It is a clinometer. I suppose you could use it to calculate your altitude with other data inputs and math gymnastics but the instrument itself is just a clinimeter. It measures degrees of elevation or depression from the horizon It seems to work OK, at least for checking my local horizon to make sure I would be able to see the Sun during the 2024 eclipse, but I find it clumsy to use. I am left eye dominant so my preference would be to hold it in my left hand in front of my left eye. But when I hold it in my left hand my palm covers the plastic window blocking the light that needs to get to the edge of the dial to be able to read the numbers in the viewing window. To use it properly you keep both eyes open and hold the clinimeter's viewing window in front of one of them. Your mind merges what you are seeing in the viewing window with what you are seeing with the other eye. The index line extends to the left so to go get the best superposition over what you are measuring it should be used in front of the right eye. The little black sighting window has a diopter adjustment but the threads are so coarse and sloppy that the only place it stays where you put it is when it is either screwed to the hard stop either all the way in or all the way out. If you need it somewhere between those settings you will find it has moved the next time you pick it up and you will have to spend time resetting it and hope you don't move it when you let go of it. You could get it close to where you want it by scratching an index mark on the bottom of the case and using a paint pen to put a corresponding mark in one of the viewer knurls. Unless you are going to put your right hand through the wrist strap you are better off not attaching it. When you are using the instrument it's the wrist strap's attachment point is aligned with and above the viewing window so the strap naturally wants to hang down between your eye and the window. The attachment point should be on the bottom corner of the instrument. It can not be used at night unless there is enough ambient light to illuminate the edge of the rotating dial. Trying to hold a flashlight there will get light into your left eye or, if you hold it against the plastic window, your hand and flashlight will be obstructing your view of the target. It looks like there is enough unused space between the viewing window and the rotating wheel that a watch battery and rheostat might have been included to power a small LED shining across the edge of the dial. This works, but I prefer using a quality, and much more expensive, Suunto. ⭐⭐⭐ Is my base rating for a product that is fully functional and fulfills it's promises

The flagrant misnaming of the device in the product title doesn't inspire much confidence for the seller's knowledge of the products they're brokering. For that reason alone, I wouldn't recommend buying here. It's an INCLINOMETER... which measures incline or grade tangential to horizontal plane. It is NOT an "altimeter", which measures height or altitude above sea level, and typically gives its resdings over an ooen-faced guage, like you'd find in the instrument panel of an airplane. The two instruments are nothing alike, bear no resemblance whatsoever, and do nothing to calculate the other. It looks like a good enough unit, but I prefer tandem units like the ones Suunto, Steren, and others sell. They also don't confuse the functions of their own products either.

The construction was high quality, unfortunately, the reticule line wasn’t positioned precisely, so the readings were off by 2%. Accuracy carefully measured in multiple ways. No way to calibrate. Had to return.

good

Thought the "altimeter" would give me current elevation as I hike. It does not. Clinometer works ok. And the height it measures, though NOT elevation, is relatve height of something like a tree or the tip if the slope you're about to climg or descend. I really needed something that would give me ELEVATION so Im returning this one.

Me ha gustado, muy practica y económica.
