Verified Purchase(What's this?)
This review is from: Casio Men's SGW300H-1AVCF Twin Sensor Multi-Function Digital Sport Watch (Watch)
I purposely bought this watch for the altimeter feature. I have set and reset the proper altimeter reading, but it doesn't remain constant. It will change almost every time I change altitudes. I live in a hilly area where it isn't uncommon to have a 900 ft. elevation change in a 10 to 15 minute drive. After I have driven this distance, the setting will change anywhere from 200 to 600 ft. It is very unreliable. I am very disappointed in the product.
