So I just got myself a Riseman (flying squirel), I’m a little disapointed with the accuracy from the sensor however and I’m just wondering if they’re generally not as accurate as protreks or whatever.
For instance I know my elevation at home is more or less 160ft, I walk my dog the same place every day and my old PRT-30 increases 60ft to 220ft which I know is right from gps. With the Riseman I set the reference altitude to 50m and at the same point where the PRT-30 always reads 220 ft the Riseman says 80/85m, so between 38/53ft off.
Also the PRT-30’s barometer has never been adjusted and is never off by more than 1mb either way. I adjusted the Riseman to read the same as the PRT-30 and yet still it can be out of line either way by up to 3mb.
Help me experts.
