Digital Compass vs Analogue Compass

Hi guys,
I'm currently using an analogue compass to assist with the initial stages of polar aligning my SCT. However, I have noticed that the needle is influenced heavily by a few factors:

1. Being too close to the ground (blue metal dust under terazzo tiles)
2. Being too close to my back fence (colourbond)
3. Being too close to my telescope

Unfortunately, my telescope is close to a colourbond fence and is sitting on the blue metal dust / terazzo tiles.

I was wondering if anyone here knows if digital compasses are as easily influenced as the analogue ones.

Dean
