How To Change Air Tank In Sons Of The Forest: A Complete Survival Guide
Struggling to breathe during your deep-sea dives or while exploring the flooded caves of Sons of the Forest? You’re not alone. One of the most overlooked yet critical aspects of surviving the island’s treacherous aquatic environments is managing your air tank. Running out of oxygen is a swift and frustrating way to meet your end, often when you’re seconds away from treasure or a crucial resource. This comprehensive guide will walk you through everything you need to know about locating, replacing, and maintaining your air tank, ensuring your underwater expeditions are safe and productive. Whether you’re a new survivor or a seasoned player looking to optimize your dives, mastering this mechanic is non-negotiable for long-term success.
The oxygen system in Sons of the Forest adds a layer of realistic tension to exploration. Unlike surface survival where hunger and thirst are primary concerns, the underwater world introduces a race against a depleting meter. Your air tank is your lifeline down there. Knowing how to change an air tank in Sons of the Forest isn’t just a minor skill—it’s the difference between a fruitful dive and a permanent respawn. This article will demystify the entire process, from identifying a faulty tank to performing a seamless swap, complete with pro tips and common pitfalls to avoid.
Understanding the Air Tank System in Sons of the Forest
What is an Air Tank and Why Does It Matter?
In Sons of the Forest, the air tank is a piece of equipment that provides your character with a finite supply of breathable oxygen when submerged. It’s an essential tool for accessing areas like the underwater cave systems, shipwrecks, and hidden loot stashes that are inaccessible from land. The tank is not an infinite resource; it has a durability or capacity that depletes with use. Once it’s empty, your oxygen meter begins to drop rapidly, leading to drowning. The tank itself is a physical item in your inventory that can be damaged, lost, or replaced. Understanding its role is the first step to surviving the island’s aquatic challenges.
How the Oxygen Mechanics Work
Your oxygen meter is the blue bar that appears when you submerge. It depletes at a steady rate based on your activity—swimming normally uses less oxygen than sprinting or fighting underwater. The air tank you have equipped directly replenishes this meter. When the tank’s internal resource is exhausted, it stops refilling your oxygen, and the meter begins to fall. The game doesn’t always make it obvious when your tank is about to run out; you might only notice when the oxygen warning starts flashing. This is why proactive management is key. You should always check your tank’s status before committing to a long dive. A good rule of thumb is to turn back when your tank’s indicator (often a small icon or durability bar in the inventory) reaches 20%.
Prerequisites for Changing Your Air Tank
Gathering the Necessary Tools and a Replacement
Before you can swap out a depleted or damaged tank, you need two things: a new or full air tank and the correct tool for the job. The primary tool is the Wrench. You can craft a wrench at a workbench using 5x Plank, 5x Metal Sheet, and 5x Nail. Alternatively, you can often find wrenches in toolboxes in abandoned camps, inside the underground bunker, or on the bodies of fallen soldiers. For the replacement tank, you can find them in several locations: inside the wrecked ship on the beach, within underwater crates, or occasionally as loot from certain enemies. Always keep at least one spare air tank in your inventory when planning any significant underwater exploration.
Identifying a Safe Location to Perform the Swap
You cannot change your air tank while underwater. The process must be done on dry land (or at least on a surface where you can stand). Therefore, planning your dive routes with safe swap points in mind is crucial. These are locations like shallow pools, rocky outcrops near your dive site, or the entrance to an underwater cave where you can briefly surface and stand. Rushing to replace a tank while drowning is impossible; you’ll die if you don’t reach a safe spot first. Scout your route beforehand and mentally note these emergency stations. This foresight can save your life and the valuable loot you’re carrying.
Step-by-Step Guide to Replacing Your Air Tank
Step 1: Access Your Inventory and Locate the Tank
First, you must be on solid ground. Press the inventory key (default I on PC). Your inventory screen will show all carried items. The air tank is typically located in the “Back” or “Equipment” slot, often represented by a scuba tank icon. If you have multiple tanks, the one currently equipped and supplying oxygen will be highlighted or indicated. Hover over the tank icon to see its current durability or oxygen percentage. If it’s at 0% or shows as “Damaged,” it’s time for a replacement.
Step 2: Select the New Air Tank and the Wrench
In your inventory, ensure you have a full air tank and a wrench placed in separate slots. The wrench must be in your quick-bar or easily accessible in your inventory. You do not need to “equip” the wrench like a weapon, but you must have it selected as the active tool in your hand when you initiate the swap. Click on the new, full air tank in your inventory to pick it up (your cursor will hold the item). Do not place it in any slot yet; you will use it directly in the next step.
Step 3: Initiate the Replacement Animation
With the new air tank held in your cursor and the wrench in your hand (or selected in your inventory), close the inventory screen. Your character should now be holding the new tank. Approach your current, depleted/damaged tank that is still equipped on your back. You will see a prompt appear, usually something like “Press E to Replace Air Tank.” Press the designated key (E by default). Your character will then play a short animation of using the wrench to unbolt the old tank and bolt on the new one. This takes a few seconds and leaves you vulnerable, so ensure the area is clear of enemies.
Step 4: Confirm the Swap and Dispose of the Old Tank
Once the animation completes, the prompt will disappear. Open your inventory again. The old, empty/damaged air tank will now be in your inventory as a separate item (it will show 0% durability or “Broken”). The new tank will be equipped on your back, and your oxygen meter will refill to 100% (or the new tank’s capacity). The old tank is now just junk. You can either drop it to free inventory space or, if you have the Recycle perk or a suitable workbench, break it down for scrap materials like Metal Sheet and Rubber. Never forget to discard the old tank; carrying it wastes precious slot space.
Troubleshooting Common Issues
“The Replace Prompt Isn’t Appearing”
This is a frequent frustration. The most common cause is not having the wrench actively selected in your hand. Even if it’s in your inventory, you must have it equipped as your active tool. Open your inventory, drag the wrench to your hotbar, and select it (usually keys 1-5). Another cause is not having a full air tank directly in your cursor. You must click on the full tank in your inventory to pick it up before approaching the old tank. Lastly, ensure you are standing on a surface where the game allows interaction—very uneven ground or water can sometimes block the prompt.
“My Oxygen Isn’t Refilling After the Swap”
If you’ve successfully replaced the tank but the oxygen meter remains low, there are a few possibilities. First, check if the new air tank itself is actually full. Hover over it in your inventory; it should show 100% or a high value. If it’s low or damaged, you found a faulty replacement. Second, you might be experiencing a bug. Try unequipping and re-equipping the tank manually by dragging it from your inventory to the back slot. Third, ensure you are not still underwater with a critical oxygen deficit; sometimes you need to surface and take a breath first for the game to register the new tank’s supply.
“Can I Replace an Air Tank Underwater?”
No. The game mechanics do not allow for equipment swaps while submerged. You must reach a point where you can stand. This is why planning safe swap points is critical. If you miscalculate and your tank dies in the middle of a large cave, you are likely doomed unless you can find a shallow ledge or air pocket. Some players use the rebreather perk (if available via mods or specific game versions) to extend their oxygen, but the fundamental rule remains: tank replacement is a surface-only activity.
Best Practices for Air Tank Management
Always Carry a Spare
The golden rule of Sons of the Forest aquatic exploration is: never dive with only one air tank. Your primary tank is your lifeline, but your spare is your insurance policy. Dedicate one inventory slot (often the “Back” slot can hold two if you use a backpack, but standard is one equipped) for a full spare. This way, if your main tank fails unexpectedly—due to damage from a creature attack or a hidden leak—you have an immediate backup. The spare should be checked and rotated regularly; don’t let it sit at 100% forever if you’re not using it, but also don’t use it as your primary and then have nothing left.
Monitor Your Tank’s Durability Proactively
Don’t wait for the oxygen meter to hit red. Periodically open your inventory (I) and check the air tank’s durability percentage. Treat it like checking your weapon’s ammo. A good habit is to check every time you surface at a safe point. If it’s below 30%, consider swapping it out then and there while you have the time and safety. This proactive approach prevents panic situations. Some players even rename their tanks in their mind (“Tank A – 75%”, “Tank B – 100%”) to keep track.
Know Your Tanks and Their Sources
Not all air tanks are created equal in terms of where you find them. The standard tank from the shipwreck has a fixed capacity. Some community mods or later game updates might introduce upgraded tanks with larger capacity, but in the base game, capacity is standard. However, the condition varies. A tank found in a pristine military crate might be 100%, while one pulled from a sunken boat might be 30%. Always assess the condition before relying on it. Also, learn the map: key locations like the cave entrance near the beach, the sunken yacht, and the military bunker are prime spots to scavenge for spare tanks.
Crafting and Long-Term Sustainability
While you can’t craft a new air tank from scratch in the base game (it’s typically found loot), you can sustainably manage your supply. The old, broken tanks you collect can be recycled at a workbench for valuable Metal Sheets and Rubber. These materials are essential for crafting other tools, weapons, and base components. This creates a loop: use tanks, recycle the husks, use materials for other survival needs. If you’re playing with mods that allow crafting, you might be able to create tanks using Metal Sheet, Rubber, and Glass, but verify your specific mod’s recipes.
Advanced Tips for the Seasoned Survivor
The “Double Tank” Technique
Some players, especially those with larger inventory mods or using the Backpack item, manage to carry two full air tanks—one equipped and one in a backpack slot. The equipped one is used automatically. If it runs out, you must unequip it and equip the spare from the backpack, which is faster than a full inventory swap. This method requires careful inventory management but can shave crucial seconds off your response time during an emergency.
Using the Watch for Precision
Your character’s watch (press C by default) shows a detailed oxygen meter with numerical percentages when underwater. Get in the habit of glancing at it instead of just relying on the color-changing bar. Knowing you have exactly 15% oxygen left is more actionable than seeing a “low” bar. This precision allows you to calculate your return trip time accurately and avoid cutting it too close.
Environmental Awareness During Swaps
When you stop to change your air tank, you are stationary and making noise. This is a prime moment for aquatic predators like the mutant fish or sharks to attack. Always perform swaps in areas you’ve cleared or that are naturally safe (shallow, with no visible threats). Have your weapon ready immediately after the animation finishes. Some players even place a flare or torch nearby while swapping in dark caves to illuminate potential threats.
Conclusion: Breathing Easy in the Depths
Mastering how to change an air tank in Sons of the Forest transforms the island’s waters from a deadly barrier into a highway for exploration and loot. It’s a simple mechanic with profound implications for your survival strategy. Remember the core流程: locate a safe spot, have a wrench and full tank ready, perform the swap on land, and always carry a spare. Integrate proactive monitoring into your routine, and you’ll find yourself diving deeper, staying longer, and returning with treasures that would have been impossible before.
The island’s secrets are often hidden beneath the waves, guarded by pressure and darkness. By taking control of your oxygen supply, you take control of your access to those secrets. Don’t let a preventable drowning be the reason you miss out on the next game-changing weapon or resource cache. Prepare, practice, and plunge with confidence. Your next successful dive—and your continued survival—depends on it. Now, grab your wrench, check your tanks, and go claim what the depths are hiding.
