How the Dockmaster’s Detector actually works in-game
The Dockmaster’s Detector functions as a proximity-based scanner that reacts to hidden loot buried beneath the environment. When equipped and activated, it begins emitting audio signals that guide your movement.

The key mechanic revolves around sound frequency. At a distance, the device produces slow, spaced-out beeps. As you move closer to a hidden stash, the beeping becomes faster and more intense. This creates a natural “hot-and-cold” tracking system that you can follow intuitively.
You can see visual markers as colors. You also have to rely on sound cues and positioning. This makes the detector especially useful for players who enjoy exploration-based gameplay rather than direct waypoint tracking.
How to use Dockmaster’s Detector in Arc Raiders
Step 1
Equip the Dockmaster’s Detector from your inventory before heading into Riven Tides. Make sure it’s placed in a quick-use slot so you can activate it instantly.
Step 2
Activate the detector while exploring open areas, especially sandy or coastal zones. These are the most common locations where buried loot appears.

Step 3
Listen carefully to the beeping pattern. A slow beep means you’re far away, while faster beeps indicate you’re getting closer to the target.
Step 4
Move in the direction where the beeping intensifies. Adjust your path gradually instead of sprinting randomly, as subtle changes in direction help pinpoint the exact spot.

Step 5
Once the beeping becomes rapid and continuous, search the immediate area closely. This usually means you are within a few meters of the buried loot.
Step 6
Interact with the ground or highlighted spot to dig up or collect the hidden item. Rewards can vary depending on spawn RNG.

Understanding durability and maintenance
One of the most overlooked aspects of the Dockmaster’s Detector is its durability system. Every time you use it, the item slowly degrades.
You’ll notice visual cues like smoke or damage effects when the detector is close to breaking. This is your warning sign to stop overusing it or prepare for repairs.

If the detector breaks completely, you risk losing access to treasure scanning entirely, especially since it cannot be easily replaced.
Repairing it is possible, but you’ll need the right resources and access to a repair station. Always keep an eye on durability before heading out on long runs.
Where to use it effectively in Riven Tides
The Dockmaster’s Detector is most effective in open, sandy, and coastal regions of Riven Tides. Areas near docks, beaches, and abandoned shoreline structures tend to have higher chances of buried loot.

Avoid using it excessively in dense urban or indoor areas, as the chances of finding buried treasure there are significantly lower.
Patrolling wide-open terrain in a systematic pattern yields the best results, especially when you combine slow movement with careful listening.
What kind of rewards you can expect
The loot you uncover using the Dockmaster’s Detector can vary widely, making it a high-risk, high-reward tool.
| Reward Type | Examples |
|---|---|
| Crafting Materials | Durable Cloth, Components |
| Utility Items | Rare tools and consumables |
| Event Items | Special collectibles like ship models |
| Random Loot | Unique items tied to region RNG |
In some cases, players have reported finding rare collectibles and event-specific items, making the detector especially valuable during limited-time events.
Practical tips to improve your scanning efficiency
Moving slowly and methodically is far more effective than rushing around randomly. The detector is designed for precision, not speed.
Use headphones if possible, as directional audio helps you track signal changes more accurately.
Avoid scanning in combat-heavy situations, since distractions can cause you to miss subtle audio cues.
Combine scanning with map awareness, focusing on areas that logically make sense for buried loot, like shores and abandoned zones.
The Dockmaster’s Detector transforms exploration in ARC Raiders into a rewarding treasure-hunting experience. When used correctly, it gives you access to hidden resources that most players overlook.
Mastering its audio-based tracking system is the key to maximizing its value. Once you get comfortable reading the beep patterns, you’ll start locating loot faster and more consistently.
If you treat the detector carefully, maintain its durability, and use it in the right areas, it can become one of your most valuable tools in Riven Tides.
