Arc Raiders Beachcombing Guide (May 2026) Riven Tides Loot Tips

The Arc Raiders Beachcombing map condition is the single weirdest thing Embark has dropped into Riven Tides, and I’ve been hooked on it since launch night. It’s part metal-detector minigame, part PvP death trap, and part “why is there a bomb in this suitcase.” This guide breaks down exactly how I run it.

Here’s what’s inside:

• How Beachcombing actually works on Riven Tides
• Three ways to grab a Dockmaster’s Detector
• Where to dig (and where you’re wasting your time)
• The light/sound signals so you stop guessing
• What I’ve pulled out of the sand so far
• How to not get clapped by the new ARC Turbine while you’re staring at a beeping stick

I spent most of my first night on the new map thinking the detector was busted. Spoiler: it wasn’t. I just had no idea what the orange light meant. Let’s fix that for you.

What Beachcombing Actually Changes on Riven Tides

Beachcombing is a minor map condition that came in with the 1.26.0 Riven Tides patch. The key word there is minor. It’s not a major event like Night Raid or an Electromagnetic Storm where the whole map mood flips. It’s a quieter modifier that just unlocks a new loot system on top of normal Riven Tides runs.

The way the rotation works in 2026, map conditions cycle every hour. So Beachcombing isn’t always live — you’ve got to actually check the matchmaking screen for that little tag before you queue up. If it’s not there, your Dockmaster’s Detector is a paperweight. I learned that one by queuing into a regular Riven Tides game with my detector equipped, scanning every dune I could find, and getting absolutely nothing for 20 minutes. Don’t be me.

When the condition is active, buried loot spawns under the sand in specific zones. You can’t see it. You can’t hear it. The only way to find it is by sweeping the ground with the detector. That’s the whole loop: queue → land → run to the beach → scan → dig → run before someone shoots you in the back.

Compared to other map conditions, this one’s pretty chill on paper. It’s not actively trying to kill you. But here’s the catch nobody mentions until you’ve eaten dirt a couple of times — the richest dig spots are way out in the open. Wide-open coastline. Zero cover. Zero excuses.

How I Got My First Dockmaster’s Detector

There are three real ways to get one. I’ve used all three. Ranked by how fast they get you scanning:

1. Pick up the “Shoring Up Defenses” quest from Apollo. This is the fastest path. The second you accept the quest in Speranza, Apollo just hands you a Dockmaster’s Detector. You don’t even need to complete anything. Walk over, grab the quest, walk out with a free metal detector. This was easily the cleanest unlock for me.
2. Knock out Stage 1 of the Avian Alarm project. This is the new player project tied to Riven Tides. Stage 1 just asks you to lay a bird trap next to one of the buoys buried in the sand in the Seabed area, northeast of the Port Authority Building. Reward is a detector plus 25 Raider Tokens. If you’re already going to grind the Avian Alarm for the Bird House backpack and the Fist In Air emote (and you should), Stage 1 is basically free.
3. Loot containers on Riven Tides while Beachcombing is active. This is the RNG path. Detectors spawn in shipping containers and other crates, and the Stacking Yard area seems to be the most consistent spot people are reporting. I’ve personally pulled three out of red lockers in a single run. Once you’ve got the project going and the quest done, this becomes your “I died and lost mine” backup plan.

Quick note on losing it: yeah, you can. The detector goes on your quick-use wheel like a gadget, but it lives in your inventory, which means if you get knocked out and someone loots you, your detector is on their character now. So if you’re carrying a fat stack of dig loot, get out before you get greedy.

The Seabed Is Where the Loot Lives

This is the part I really wish I’d known before my first run. Buried treasure mostly spawns in the dried-up Seabed area in the north part of Riven Tides. Not the resort beaches near Panorama Azzurro. Not the random sand patches near the docks. The Seabed.

The Seabed is that big, exposed flat in the upper section of the map — what used to be ocean floor before whatever the heck happened during the Exodus dried it all up. It’s basically one massive cracked-mud-and-sand expanse with old buoys sticking out of it. Visually it’s gorgeous. Tactically it’s a nightmare. There is nowhere to hide out there.

I tested this on my second night. I queued five Beachcombing runs and made a point of scanning everywhere — the south coast near the resort, the dockyard sand patches, even the random sandy bits around the Stacking Yard. I pulled exactly zero buried items outside of the Seabed. Inside the Seabed, I was hitting orange beeps within about 30 seconds of activating the detector.

So if you’re trying to be efficient, your spawn-to-Seabed route matters more than your loadout. Land, sprint, scan. The longer you wait, the more likely it is some other Raider has already worked that section of the beach.

Reading the Detector Without Getting Sniped

The detector itself is dead simple once you know what the lights mean, but the in-game tutorial does a terrible job explaining it. Here’s the actual flow:

1. Equip the detector from your quick wheel (it occupies a slot, just like a grenade or healing item).
2. Hold the activation button to sweep. This drains stamina, which is honestly annoying.
3. No light, no beep = nothing buried close. Move along the beach.
4. Orange flashing + slow beep = treasure is somewhere in your zone. Walk in different directions and watch how the beeping speed changes.
5. Faster orange beeping = warmer. You’re closer.
6. Green flashing = you’re basically on top of it.
7. Steady solid green light = stop. Put the detector away. The dig prompt should pop up.
8. Hold the dig prompt. Wait through the animation. Loot pops out of the sand.

The triangulation part is where most people screw up. You can’t just stand still and rotate — you have to actually walk a few steps in one direction, scan, walk a few more, scan again, and read the rate of beeping like a hot/cold game. If the beeping slows down, you walked the wrong way. Turn around.

The other thing nobody tells you: the detector takes up a slot you’d normally use for something else. So you’re not running it on top of a grenade — you’re running it instead of. That tradeoff matters more than you think. I usually drop a flashbang or a smoke for it, because at least smoke gives me an “oh god they spotted me” panic option.

What I’ve Actually Dug Up So Far

I’ve done probably 20 successful digs at this point and the loot variance is real. Here’s a rough breakdown of what I’ve personally pulled:

• Buried suitcases stuffed with crafting materials (most common)
• Weapon cases — yes, full weapon cases, the same ones you find around the map
• An Il Toro shotgun straight up sitting in the sand
• Several of the new Ship Model trinkets (Wind Sprite was the most common, I got a Leviathan’s Crown once and almost cried)
• A bomb. An actual bomb. With a timer. More on that in a second.
• Ticks. Multiple Ticks. They jump straight at your face the moment you finish digging.

The Ship Models are the big sleeper here. They’re worth real XP at extraction and they feed straight into the Last Resort event for merits. So even on a “bad” dig you can come out ahead if you pull a model.

I learned the bomb thing the hard way on my third dig of the night. Detector goes solid green, dig animation plays, and instead of a suitcase I get a beeping cylinder that needs to be defused before it cooks me. I panicked, ran in the wrong direction, and ate full damage. Whole run dead because I dug like a tourist. Now I always crouch a half-second before the dig finishes so I can move fast if it’s a “surprise.”

The ARC Turbine Almost Wiped My Best Run

I have to talk about this because it changes how you approach Beachcombing. Riven Tides shipped with a brand new enemy called the ARC Turbine — a floating drone that just sort of drifts across the Rust Belt. It’s chill if you ignore it. The second you engage, though, it’s a whole encounter with mechanics most of us are still figuring out.

Here’s why it matters for Beachcombing: the Seabed is exactly where the Turbine likes to drift over. Wide open sky, no terrain to break line of sight, your character is staring at the ground holding a beeping stick. You’re a free kill if you’re not paying attention.

My rule now: every time the detector goes orange, I scan the sky before I commit to walking deeper into open ground. If I see a Turbine drifting in, I either book it back to cover and wait, or I peace out to a different stretch of beach. The dig isn’t worth dying over.

The new White Flag deployable from this patch is sometimes useful here too. If you spot another Raider out on the Seabed and they don’t seem to want a fight, dropping a flag signals you’re not looking for trouble. It works some of the time. Other times you eat a sniper round mid-animation. Read the lobby.

Why Solo Beachcombing Is a Different Game

If you’re queuing solo like I usually do, Beachcombing is significantly harder than it looks on YouTube. Everyone showing this off is in a squad with one person scanning and two people watching their flanks. That is not the experience.

Solo, your routine has to be:

• Listen for shots before you ever pull the detector out
• Sweep in short bursts, not constant scans
• Always know which direction your nearest cover is
• Extract the moment you have anything worth extracting

That last one is the discipline I’m still working on. There’s a real urge to do “just one more dig” because the orange light is right there and the beep is so close. That’s how you lose three suitcases worth of loot to a level 12 with a Bratchny.

In a squad, the meta is way more comfortable. One scanner, one or two overwatches with long-range builds. The scanner doesn’t worry about anything except triangulating. It’s almost relaxing.

Stuff I Wish Someone Told Me Before My First Dig

A handful of small tips that don’t deserve their own section but absolutely matter:

• Beachcombing is only on Riven Tides. It will never appear on Buried City, Dam Battlegrounds, Spaceport, Blue Gate, or Stella Montis. Don’t waste a detector slot anywhere else.
• The detector is technically a Common gadget, so it’s not rare — but it’s only useful inside this map condition.
• You can scan while crouched. Slower, but way less visible to other Raiders.
• The dig animation locks you in place for about 3 seconds. Pick your moment.
• Loot quality reportedly scales toward the more exposed parts of the Seabed. The richer the dig site, the worse the cover. That’s by design.
• If you’re going to extract early with a fat haul, the southern extracts are usually a safer route from the Seabed than backtracking through the resort area.
• A bug at launch reportedly stops the “Off The Radar” quest from being completed on Riven Tides — that’s an Embark known issue, not your fault. Don’t grind your head against it until they patch it.

Beachcombing FAQ

---

Beachcombing in Arc Raiders is one of those mechanics that looks dumb on paper and ends up being the most fun I’ve had on a new map in months. Once you’ve got the Dockmaster’s Detector, you know the Seabed is the spot, and you’ve stopped panicking when the light flashes orange — you’re basically printing loot. Just don’t get cocky out there. The sand has bombs.
