    This has been shown to be as accurate as an analogue instrument can be. I’ve checked it against GPS and USGS survey markings.
    It’s usually within 50 to 100 feet.

    Make sure you read the short instructions before you do any adjusting. Don’t mess with the screw on the back unless you are SURE of what you are doing. That changes the barometric pressure setting. The outer ring on the front changes only the altimeter reading.

    This in combination with a topo map and compas is far superior to a GPS on thru hikes because you don’t need batteries. Nice to know that this device will keep functioning indefinitely unless pegged out somewhere like Nepal. Make sure you adjust properly if you are above 14000 feet.

    This is a good basic altimeter, which has the benefits of being an old-school analog device. It is intuitive to use and easy to calibrate as the barometric pressure changes with the weather. It is easier to read as an altimeter than as a barometer, but for most that is a good trade off.

    A great product but could really
    use a calibration lock.
    A small screw clamp for the calibration would get it a 5 star review. Until then I’ll keep using a small bit of duct tape on the face and rim.

    On my John Muir Trail hike, I compared the accuracy with known heights. It was very accurate. Easy to recalibrate if needed to be done too.

    One thing confusing about it, I wanted to remove the lanyard to reduce weight, I thought I had to rotate the middle back screw. Leave that one alone. I did attend to the tiny side screws on the back. When done, you just have a little difficulty doing a pop out of the altimeter.
