Electronic Sensors & High Tenacity Fibers in DMZ

Electronic sensors and high tenacity fibers are two of the most sought-after items in Call of Duty: Warzone 2’s DMZ mode, used for upgrading your insured weapon slots and completing faction missions. You can find them by looting supply boxes, medical boxes, and toolboxes across Al Mazrah, with the highest drop rates in restricted areas like the Al Bagra Fortress and the observatory, and by killing specific AI commanders like the Chemist. Below is a detailed breakdown of where to look, how to increase your chances, and what these items are actually for.

Formula

This calculator works out your average pace (time per kilometer) and average speed (kilometers per hour) for a given distance and finish time. The formulas are:

• Average pace = Finish time (minutes) ÷ Distance (km)
• Average speed = Distance (km) ÷ (Finish time (minutes) ÷ 60)

Where finish time is in minutes, distance is in kilometers, pace is in minutes per kilometer, and speed is in kilometers per hour.

Worked Example

Using the default values (50 minutes, 10 km):

1. Pace = 50 ÷ 10 = 5.00 min/km
2. Speed = 10 ÷ (50 ÷ 60) = 10 ÷ 0.8333 = 12.00 km/h

The calculator shows a pace of 5.00 min/km and a speed of 12.00 km/h.

Where to Find Electronic Sensors

Electronic sensors are a common drop from supply boxes, medical boxes, and toolboxes scattered across Al Mazrah. They are also found in duffel bags and backpacks on AI soldiers. The highest probability locations are:

• Al Bagra Fortress – the underground tunnels and armory rooms have multiple toolboxes and supply crates.
• Observatory – the main building and surrounding shacks contain several electronic spawns.
• Said City Mall – electronics stores and back rooms have a high density of lootable containers.
• Airport – luggage carousels and maintenance areas often yield sensors.

Killing the Chemist (the boss in the radiation zone) also has a chance to drop electronic sensors, but the drop is not guaranteed. For a more reliable method, focus on looting every container you see in the areas listed above.

Where to Find High Tenacity Fibers

High tenacity fibers are rarer than electronic sensors and are typically found in medical boxes, toolboxes, and military supply crates. They also drop from AI soldiers in high-tier zones. The best locations are:

• Al Bagra Fortress – the same loot pools as sensors, but fibers are less common.
• Hydroelectric – the dam control rooms and worker sheds have multiple toolboxes.
• Rohan Oil – the refinery buildings and storage tanks contain military crates.
• Koschei Complex – if you have access, the underground bunker has a high density of toolboxes and medical boxes.

High tenacity fibers are also a possible reward for completing Faction Missions that specifically ask for them. If you need a large quantity, consider doing a few missions that reward them.

How to Increase Your Drop Chances

Loot spawns are randomized each match, but you can improve your odds with these strategies:

• Use a keys – certain locked rooms (e.g., the Al Bagra Fortress Armory key) have a higher chance of spawning rare items like fibers.
• Loot everything – don’t skip small containers; sensors and fibers can spawn in any box.
• Kill AI soldiers – higher-tier AI (elite and heavy) have a better chance of dropping these items.
• Check the map – the Dead Drop locations sometimes have a small stash that includes these items.

Remember that items are not guaranteed – you may need to loot several containers before finding one.

What These Items Are Used For

Electronic sensors and high tenacity fibers are primarily used for upgrading your insured weapon slots. The upgrade requires a certain number of each item (e.g., 2 sensors and 3 fibers for the first upgrade). They are also used in some Faction Missions (e.g., White Lotus and Black Mous) as a delivery item. You can store them in your backpack or in a secure backpack to keep them after exfil.

Common Mistakes and Misconceptions

A common mistake is assuming that these items only spawn in specific buildings – in reality, they can spawn anywhere, but the probability is higher in the areas listed. Another misconception is that you need to exfil with them to use them; actually, you can use them immediately if you have them in your backpack when you upgrade your slot. Also, note that dying with these items will lose them unless you have a secure backpack.

Frequently Asked Questions

Do electronic sensors and high tenacity fibers spawn in Ashika Island?

Yes, they do spawn on Ashika Island, but the drop rates are similar to Al Mazrah. The best spots are the underground bunkers and the castle area. However, Al Mazrah has more containers overall, so it’s often easier to find them there.

Can I find these items in the Koschei Complex?

Yes, the Koschei Complex has a high density of toolboxes and medical boxes, making it a good place to find both items. The underground area has many lootable containers, but be prepared for strong AI resistance.

What is the fastest way to get high tenacity fibers?

The fastest way is to loot the Al Bagra Fortress and the observatory in a single match, focusing on toolboxes and medical boxes. If you have a key to a locked room, use it – those rooms have a higher chance of spawning rare items. Alternatively, complete a faction mission that rewards fibers.

Do these items count if I put them in a secure backpack?

Yes, items in a secure backpack are kept even if you die, and they count toward your upgrade progress. You can store them and use them in a later match.

Are these items used for anything besides insured slot upgrades?

Yes, they are also used in several faction missions, such as delivering a certain number of sensors or fibers to a dead drop. Check your mission list to see which ones require them.

Can I buy these items from a buy station?

No, electronic sensors and high tenacity fibers cannot be purchased from buy stations. They must be looted or earned as mission rewards.
