    ARC Raiders – How to Use Dockmaster’s Detector

    By Kirthana KApril 28, 2026Updated:May 3, 20264 Mins Read

    ​Key Points​

    • The Dockmaster’s Detector is a unique gadget that is to be used during the Beachcombing event.
    • You can loot it around the various maps, especially around Riven Tide.
    • With this, you get to find valuable treasure spots to dig and get items.

    The new Riven Tide map in ARC Raiders offers the Beachcombing map event. But this event has a requirement, as you can’t participate without a Dockmaster’s Detector. This device acts as a metal detector and will trigger whenever it finds treasure nearby.

    ​How to Get the Dockmaster’s Detector

    ​The Dockmaster’s Detector is a critical instrument that lets you detect treasure buried underground. If you haven’t obtained the Dockmaster’s Detector yet, there are three common ways to get it. After progressing through the new questline a bit, you will encounter the Shoring Up Defenses quest. Completing this quest will give you a Dockmaster’s Detector.

    ​Besides this, you will also get this gadget if you have completed the Place Bird Trap quest objective for the Avian Alarm Project. And finally, you might find this item on the bodies of fallen players, or by looting containers during map events. If you are going for this option, then the best way I found is to wait around for the Beachcombing event, since this event triggers a higher drop rate of Dockmaster’s Detectors.

    ​How to Use the Dockmaster’s Detector

    ​Head into your inventory and equip the Dockmaster’s Detector in your loadout’s quick slot. To use the device, just press down on the activate button to start the device. Then, walk around the area while aiming at the ground. If it starts beeping either orange or green, then you are close to or on top of the treasure. The faster the beeping gets, the closer you are to your target.

    ​Once the flashing stops and the green light stays on continuously, then this is the spot to dig. Be careful, as some of my digs yielded some nasty surprises like Ticks or surprise bombs. But the effort is worth it, as I also had some stroke of luck in finding extremely valuable materials.

    ​The best use for the Dockmaster’s Detector is during the Beachcombing event that appears occasionally around the Riven Tide map. I found one particular area that always had hidden treasure. The area in question is in the northern section of Riven Tide, near the Seabed. Use the device around the dried-up shoreline to find a unique treasure spot with valuable items inside.

    ​FAQs​

    Is participating in the Beachcombing event worth it?

    ​This event is a high-risk, high-reward occasion, which means that you might find valuable treasure at the cost of defending your spot from other players and/or enemies. If that seems like the right challenge for you, then you should definitely give this event a go.

    ​I can’t find any Dockmaster’s Detectors while scavenging. What do I do?

    ​You can try the other two quest methods to get the Dockmaster’s Detector quickly instead.

    ​Someone looted the Dockmaster’s Detector off me. What do I do?

    ​There are other Dockmaster’s Detectors to find in the wild or through quests, so go ahead and use those methods to get another one.

    ​Is the Dockmaster’s Detector craftable?

    ​No, you cannot craft the Dockmaster’s Detector nor purchase it from vendors. The only way to get it is via the above-mentioned methods.
