am looking for an accurate altimeter for my motorized parachute. A wrist-worn altimeter would probably be better than a golf laser rangefinder when dropping to earth from over 1,200 feet. By the time you get a reading from the LRF, you've fallen a good 100ft or so. I would check skydiving safety standards and see if laser rangefinders are an acceptable altimeter!!!

No, it works fine, only I don't like the voice activation. I struggled to turn them off...LOL

The measurement distance of the product must be more than 5m and cannot be measured through the glass. The above two methods will result in no data being measured and the measurement will fail.
