how to find bunkers?

[JFJ]

last time I played this bunkers were easy to find since they were marked with a green blip.
Those are gone now, I found a laptop that highlights the 3d printer cave but i can't seem to find anymore laptops in any easily accessable caves to highlight the bunkers, how am I supposed to find them naturally without a guide?

I feel horribly lost now.

The caves are the key. The rebreather cave, the cave closest to the crash site at the ocean, has a laptop computer inside. I believe that laptop will GPS-tag Maintenance Bunker A (shown with a green circle). Each bunker, in turn, will have a laptop that leads to another bunker. Eventually, you'll get through all bunkers.

The unlockable locations by laptop were added quite some time ago, you need to explore more caves and any locations you manage to uncover to find more, I wish you luck in your exploring.
