If you wish to accomplish the Defiance 2050 pursuits, you will have to find the data loggers. There are nine hidden in the Marin area. Follow the guide !
We are here at home
First of the Top-Notch recorders, this one is on one of the rocks with a wind turbine, below the access ramp. To know where to climb on the railing, it's simple: there is a post.
Aim right and jump to land on the rock, or you'll have to start over, as there's no way to get up there once in the water.
Not my most glorious hour
Second Top-Notch recorder, it's at the top of the stairs, to the right when you get to the complex.
Climb to the second floor, the recorder is at the end of the balcony.
This is your universe
You won't have to fight for this logger that's in some trash to the left of Dogstown Mine.

Go to the union headquarters and identify this large building, just in front of the entrance. Go inside (I aim for my gun door).

Go to the Towers Quarry, I advise you to do it, like me, from the hills at the back, as the recorder is in the first building at the bottom.
He's on the ground, in a corner.
The Black Mouths of 99
This recorder is in the Mill Valley mines on one of the towers. Climb upstairs thanks to the ladder, it is on the ground behind the corrugated sheets.
Subject RR24F - Session 3
The recorder is located below the dam of the Muir power plant. Approach from the east, and identify the truck that is in the screenshot below on my right, behind the barrier.
The recorder is in the dumpster:
The return of Joe the Virtue
The only recorder also in the west, it is located in the Bolinas Foundry. Enter through the main door, and turn left without passing the big truck.
Climb the yellow ladder, then walk along the building until you see, on the side, boxes that will allow you to access the upper floor.
The recorder is at the end of the kind of balcony.
It is all I have
The last and arguably the simplest recorder from this nerve center of the area, the Crater bar. It is on a table on the far left.
Well done, you have found all the loggers in the Marin region and its Mines of Madness.
