Pressure-port opening in Jolly Logic Altimeter Three

[MetricRocketeer]

Hi everyone,

Could someone please tell me where the pressure-port opening is in the Jolly Logic Altimeter Three (JLA3), which I purchased a few weeks ago.

I am looking at the instructions for the Jolly Logic Altimeter Two, and those instructions advise being careful not to block the pressure-port opening underneath the attachment point. So I want to exercise the same care with my new JLA3. As I am looking closely at it, however, I cannot see any such opening.

Thank you.

Stanley

The first-generation AltimeterOne/Two have a slot in the case under the attachment point. The current-generation AltimeterOne/Two/Three appear to use the space around the micro-USB charging socket as the air vent to the pressure sensor inside.

Thank you Bernard. That explains everything.
