The minimap in Abyss helps you navigate the vast underwater world without wasting oxygen or getting lost. It displays discovered biomes, teleport points, and the overall map layout as you explore deeper zones. Unlike many navigation tools, the minimap isn't available at spawn—you'll need to reach the second biome and purchase it from a specific vendor.
Quick answer: Travel to Ancient Sands (around 230 meters depth), locate Crazy Jeff's Shop inside the large stone arch tunnel, and buy the minimap. Equip it in your hotbar (press G to open backpack) and press the assigned number key to view the map.
Requirements to Reach the Minimap
You cannot access the minimap location immediately. The starting zone, Forgotten Deep, sits above the depth threshold required to reach Ancient Sands. You'll need to upgrade your tube first—specifically, you must equip at least a Zeppelin Tube or Boat Tube. Weaker tubes have depth limits that prevent you from descending far enough to enter the second biome.
Oxygen capacity also matters. The journey to Ancient Sands consumes a significant amount of oxygen, so prioritize tube upgrades that extend your dive time. If you attempt the trip with insufficient oxygen or a low-tier tube, you'll drown before reaching Crazy Jeff's Shop.

Locating Crazy Jeff's Shop in Ancient Sands
Once you have the necessary equipment, head west from the starting zone. Continue swimming west until the environment transitions to a brown, sandy seabed. The game will display a notification when you enter Ancient Sands.
At the center of this biome, you'll see a massive natural stone arch—a bridge-like structure with a large tunnel running beneath it. Swim into that tunnel and descend to the very bottom. Crazy Jeff's Shop sits at the tunnel's lowest point, marked by its entrance.
Enter the shop. You won't lose oxygen inside, so take your time. Activate the teleport point inside the shop to unlock fast travel for future visits. Then locate Crazy Jeff and interact with him. He may offer quests, but your primary goal is to purchase the minimap from his inventory.

Using the Minimap
After purchasing the minimap, open your backpack by pressing G. Drag the minimap into any of the numbered quick-use slots (1 through 9). Once assigned, press the corresponding number key to open the minimap interface.
The minimap displays everything you've discovered so far. This includes biome boundaries, the layout of explored areas, and the locations of unlocked teleports. As you venture into new zones, the map updates automatically to reflect your progress.
The minimap does not show real-time fish locations or mutation types—use the radar for that purpose. The minimap's primary function is spatial navigation: preventing backtracking, identifying unexplored regions, and planning efficient routes between teleport points.
Why the Minimap Matters
Oxygen management defines survival in Abyss. Without a map, you risk swimming in circles or venturing too far from teleports. The minimap eliminates guesswork. You can glance at it to confirm your position relative to known landmarks, measure the distance to the nearest teleport, and avoid dead-end paths that waste oxygen.
Later biomes sprawl across larger areas with more complex geometry. The minimap becomes essential once you start completing quests that require specific fish mutations or artifact locations. Instead of memorizing routes, you can reference the map to plan the shortest path to your objective.

Common Mistakes
Players sometimes attempt to reach Ancient Sands too early. If your tube can't handle 230 meters of depth, you'll hit an invisible barrier or run out of oxygen before arriving. Always check your tube's depth limit and oxygen capacity before making the trip.
Another mistake is forgetting to activate the teleport inside Crazy Jeff's Shop. If you skip this step, you'll have to swim the entire distance again the next time you need to visit. Activate the teleport immediately after entering the shop to save time.
Finally, some players expect the minimap to reveal hidden items or fish. It doesn't. The minimap only shows terrain, biome boundaries, and teleport locations. For fish tracking, you need the radar, which scans nearby creatures and displays their mutations.
The minimap transforms Abyss from a disorienting dive into a structured exploration experience. Once you purchase it from Crazy Jeff's Shop, you gain permanent access to a tool that reduces oxygen waste and streamlines quest completion. Prioritize upgrading your tube first, then make the trip to Ancient Sands as soon as you can survive the depth and distance.
