The Safe Harbor quest continues the story about the research data and tech created in Stella Montis, which has seemingly made its way to Arc Raiders' new Riven Tides map. You need to follow clues left by the hotel's restaurant kitchen staff to dig up a buried Exodus part.

Finding the chefs' clue is hard enough, so if you're not down for piecing together the information, then figuring out where the next part is buried will be a pain. I've saved you the trouble.

Find the clue left by the restaurant kitchen staff

Firstly, you need to head to the top floor of the Hotel Panorama Azzurro in the southwest of the Riven Tide map. I recommend accessing the roof using the staircase on the east side of the building. Be careful since a Shredder can spawn up here, and a Bombardier or Turbine can spawn outside, too.

Once you're on the roof, head past the open bar and into the restaurant area where you'll find the small kitchen in the southwest corner. Between the countertop and the cupboards on the west wall, you'll see the restaurant kitchen staff's clue: a tennis racket, a sign, and a bench. Interact with the prompt here to take a photo of the clue and progress to the next step.

Find the area portrayed in the sketch

Now all you need to do is go to the northwest side of the Tennis Court area, just a short walk southwest of Hotel Panorama Azzurro—there's a convenient zipline behind the hotel kitchen that'll take you to the ground floor.

Against the western fence of the Tennis Court, behind a billboard and a bench, you'll find a small shovel in the ground. Interact with the shovel to dig up the Precision Gimbal trinket item.

You then need to extract with this item, so I recommend placing it in a safe pocket if you have one, since it's a bit of a trek to an extraction lift—the closest is the Customs House, though there's no guarantee it will be open, and there's often a Rocketeer and a Vaporizer patrolling nearby.
