Quick Summary
- Found inside shipping containers on the Riven Tides map
- Given to you by Apollo when starting the quest "Shoring Up Defences"
- Rewarded by completing Stage 1 of the Avian Alarm Raider Project
Found in Shipping Containers
The Dockmaster's Detector can spawn as loot inside the shipping containers scattered across Riven Tides. If you want to start Beachcombing immediately without waiting for a quest reward, check the containers in and around the Stacking Yard area of the Riven Tides map.
Given by Apollo — "Shoring Up Defences" Quest
Apollo hands you the Dockmaster's Detector when you pick up the quest "Shoring Up Defences". If you're looking for a guaranteed source rather than relying on container RNG, grabbing this quest is the most reliable route.
Permanent Unlock: Avian Alarm Project
Stage 1 of the Avian Alarm Raider Project rewards you with a Dockmaster's Detector. It's a field task — lay a bird trap next to the buoys along the Seabed in Riven Tides. No items to gather, no hand-ins required. This is how most players will get their first one.
See our full Avian Alarm Project guide for all five stages, item requirements, and every reward including the Bird House attachment and 250 Raider Tokens.
