Sonar problem

I cant figure out why the sonars on both my copters don't seem to give a proper readings when I run sonar test on CLI. Ive done a full reset and installed the firmware a few times on both. Im running 2.5.3 on APM1 . 

When I run CLI it starts off reading 20cm .. so then I lift it up to about a meter and then it reads between 35 and 45cm.. I hold it over my head about 2 meters and it never reads more than about 80cm and the reading usually hovers between 65 and 75cm.

Anyone get the same reading? is this normal?

         I've answered on the 2.5.3 release thread but maybe you just have the wrong sonar selected in the APM Setup screen?  If you're using the 1260 you'll need to select XL-EZL0.
