Spotter Relays are valuable uncommon recyclable items in ARC Raiders BluePrints, widely used for crafting essential in-game materials and completing various mission requirements. Unlike craftable items, Spotter Relays cannot be made through workbenches, making looting the only viable way to obtain them. These small electronic components exclusively drop from defeated Spotter Drones, specialized aerial units that serve ARC Bombardier enemies. Mastering their spawn locations is key to efficient resource farming for both new and veteran players.

A core gameplay rule for Spotter Relays is critical to remember: Spotter Drones only spawn alongside active Bombardiers. After players destroy a Spotter Drone, a new pair will respawn near the Bombardier shortly, allowing continuous farming. However, if the Bombardier is defeated, all remaining Spotter Drones will flee the map, ending the farming opportunity instantly.

Best Farming Location: Blue Gate

Blue Gate stands out as the most reliable and least contested spot for Spotter Relay farming in ARC Raiders. This map features consistent Bombardier spawns with far fewer player encounters compared to other popular zones. While its open terrain offers limited natural cover, the predictable enemy spawn pattern makes it ideal for uninterrupted farming sessions.

Players can circle the central barren open area of Blue Gate to locate patrolling Bombardiers and their attached Spotter Drones. The low player traffic here minimizes the risk of third-party interference, letting players focus solely on eliminating drones and collecting relays without unnecessary combat disruptions.

Reliable Spots in Buried City

Buried City is one of the most accessible maps for Spotter Relay collection, boasting multiple fixed high-spawn zones. The parking garage near the map's hospital building is the most consistent location, with guaranteed Bombardier and Spotter Drone spawns in every raid. The multi-story garage structure provides ample cover to avoid enemy fire while targeting drones.

Additional viable spots include Santa Maria Houses and Marano Park. Santa Maria Houses feature frequent drone patrols and close-quarters combat advantages for quick drone takedowns. Marano Park is perfect for team farming, with a nearby metro exfil point for safe extraction after collecting enough resources.

Alternative Locations: Spaceport and Dam Battlegrounds

The Spaceport map offers decent Spotter Relay spawns, though with a slightly lower drop rate than Buried City and Blue Gate. Key zones here are the ARCR Items for sale Departure Building, Vehicle Maintenance area, and South Trench Tower. Night raids on the West Hangar yield the most reliable drone spawns, and surrounding industrial structures provide solid defensive cover.

Dam Battlegrounds is another underrated farming zone. The Loading Bay near the Research and Administration building regularly spawns paired Spotter Drones. The site's stacked industrial containers and building walls effectively block Bombardier attacks, enabling safe, sustained drone farming for relays.

Pro Tips for Efficient Relay Farming

Always prioritize destroying Spotter Drones first before targeting the Bombardier. This preserves the drone respawn loop and maximizes relay drops per raid. Equipping ammo-efficient weapons ensures prolonged farming without frequent inventory resupplies.

Avoid rushing to defeat Bombardiers unless you have collected enough relays. Once the main enemy falls, all leftover drones abandon the area, cutting off all potential loot. For solo players, Blue Gate and Dam Battlegrounds are optimal, while teams can leverage Buried City's dense spawn zones for faster resource accumulation.
