Oceanic Geo Air vs Shearwater Peregrine - Please help!

[jellycatsdad]

For digital compasses, of the ones I have used, they are okay for knowing which direction is north, or which direction to go back to shore, assuming you remember to calibrate it every day/dive. Anything more complicated than that and I have found them almost useless. If someone put a rotating bezel on a dive computer, I might feel differently, but there is more to a compass than a north seeking needle.

my beef is that a digital compass on a dive computer needs constant calibration and there’s no legend to indicate a lubber line to align with the body centerline. Of course, an analog compass is also affected by magnetic fields as well. When calibrated, the digital compass on my Peregrine TX is a few degrees off from my analog compass pointing towards true north.
