The Secret To Infinite Money: 7 Advanced Ways To Master The Ore Evaluator In Miners Haven
The Ore Evaluator is not just another item; it is the single most critical piece of utility equipment for any player aiming for true endgame wealth in Miners Haven. As of December 21, 2025, the meta has solidified around this Contraband-tier item, making it the foundation for the most efficient, high-value setups, including the legendary Auto Tesla Line and advanced Resetter Lines. If your base is bottlenecked or your ore value isn't skyrocketing, the problem almost certainly lies in how you are—or are not—using this powerful sorting device.
Simply owning the Ore Evaluator is only the first step; mastering its complex logic gates is what separates a novice miner from a Centillionaire. This guide breaks down the item's function, its cost, and the three absolutely essential, up-to-date setups that leverage its power to ensure every single ore reaches its maximum potential multiplier, guaranteeing exponential cash flow.
The Essential Blueprint: Ore Evaluator Profile and Function
The Ore Evaluator is classified as a Contraband-tier utility item, placing it among the most powerful and sought-after tools in the game. It was a pivotal addition to the game's economy, first introduced during the massive Reincarnation Update and later debuted in The Masked Man's shop.
- Item Tier: Contraband
- Category: Utility / Ore Progression Control
- Obtainment Method: The Masked Man's Shop, Trading, or rare chest drops.
- Approximate Cost: 220–400 Uncommon Currency (uC).
- Core Function: To redirect an ore based on a user-defined value comparison. This is the only item that allows for true value-based sorting.
- Comparison Operators: The item uses standard logical operators:
<(Less Than)>(Greater Than)≤(Less Than or Equal To)≥(Greater Than or Equal To)
Its primary purpose is to control ore progression, ensuring low-value ores are sent back through a resetter line to gain more multipliers, while high-value ores are allowed to pass straight to the furnace or final upgrader. This intelligent sorting capability is why it is often cited as one of the most important items alongside the Railgun Cannon.
Mastering the Logic Gates: How to Program Your Evaluator
The Ore Evaluator's power comes from its simple yet crucial programming interface. Understanding how to set the comparison value and operator is key to building an efficient base. The setup is always designed to create a loop, known as a Reset Line.
The Evaluator has two exits: one for ores that satisfy the condition (e.g., are less than the set value) and one for ores that do not. The correct setup should always route the "failed" ores (the ones that are still too low value) back to the start of the upgrader sequence, or at least back through a major upgrader like the Large Ore Upgrader or Daestrophe.
The "Less Than" (<) Strategy
This is the most common and effective programming strategy for creating a Resetter Line. You set the condition to be less than a specific value. For example, if you set the value to <(1(QnV)) (a high-tier value), any ore whose value is less than this will be redirected.
- Path 1 (True/Redirect): Ores that are less than the set value are sent to the side, typically back to the start of the multiplier chain to gain more value.
- Path 2 (False/Continue): Ores that are greater than or equal to the set value continue straight through to the next stage of the setup (e.g., the final furnace or a high-end upgrader like the Void Star).
This method ensures that only ores that have reached a sufficient, pre-determined value are allowed to exit the loop, preventing low-value ores from wasting time and space in the final stages of your base.
The 3 Game-Changing Setups Using the Ore Evaluator
While the Ore Repeater offers a simpler, pass-through count-based alternative, the Ore Evaluator's value-based sorting is essential for the most profitable and complex advanced setups. The following three setups represent the current meta for maximizing efficiency and income.
1. The Auto Tesla Line Resetter
The Auto Tesla Line is the gold standard for high-tier income, and the Ore Evaluator is its brain. The setup uses a chain of Tesla Refuters (or similar high-tier upgraders) to quickly multiply ore value. The problem is that eventually, the ores reach a point where the Tesla Refuter is no longer the most efficient use of their time.
The Evaluator is placed at the end of the Tesla chain. You program it to check if the ore is less than a value that is slightly higher than the maximum efficient output of your Tesla line. Any ore that fails the check is teleported back to the start of the line using a Teleporter or a similar transport utility, creating a seamless, automated loop that continues until the ore is powerful enough to pass through. This is the definition of a Shopless Resetter Line, eliminating the need for manual resets or less efficient items.
2. The Multi-Upgrader Splitter
This setup is crucial when dealing with Wide Upgraders or multiple-level Furnaces that offer diminishing returns. For example, a Large Ore Upgrader might give a 15x multiplier to ores less than 5k, but only a 10.5x multiplier to ores between 10k and 15k.
By using multiple Ore Evaluators in a sequence, you can create "lanes" for different ore values:
- Evaluator 1:
<5000sends ore to the 15x Upgrader. - Evaluator 2:
<10000sends ore to the 12x Upgrader. - Final Path: Ores greater than 10k continue to a different, more powerful upgrader or the furnace.
This ore progression control ensures every ore receives the absolute best multiplier available at every stage, maximizing overall profit and preventing value decay.
3. Railgun Cannon Alignment and Trajectory Correction
Advanced bases often use items like the Railgun Cannon or Dragon Canon to fling ores across the map into a distant upgrader or furnace.
The Ore Evaluator is used here not just for value, but for its perfect centering ability. By passing the ore through the Evaluator, it is precisely aligned, which is essential for hitting small targets after being launched by a high-speed item like the Railgun. This is a niche but powerful application, particularly in layouts where space is limited, and a high degree of ore trajectory accuracy is required for the most complex Contraband setups.
Final Tips for Ore Evaluator Efficiency
To truly maximize your base's potential, consider these advanced entity and strategy tips:
- Placement is Key: Always place the Evaluator directly after the upgrader or dropper you are trying to "reset." The ore must gain enough value to pass the check immediately before the Evaluator.
- Comparison vs. Ore Repeater: While the Evaluator sorts by value, the Ore Repeater sorts by pass count. The Evaluator is superior for high-end setups because ore value is the true measure of progression, not just the number of times it has passed through a utility.
- Schrodinger Multipliers: Pair the Evaluator with items that offer Schrodinger Multipliers or similar boosts. Knowing the exact value of the ore allows you to optimize when it hits these high-risk, high-reward items.
- Lag Management: Be aware that high server lag or ping can sometimes cause fast-moving ores to pass through the beam without being properly teleported. Optimize your base for smooth flow and check for server stability.
- The Freon Sprayer Synergy: The Evaluator is often used with items like the Freon Sprayer in compact layouts (like the Life 2K+ Centillion Setup V3) to manage ore speed and value simultaneously, proving its versatility in complex base designs.
By integrating the Ore Evaluator into your base as the central decision-maker, you move beyond simple linear progression. You create an intelligent, dynamic system that continuously optimizes the value of every single ore, providing the foundation for reaching the highest Prestige levels and achieving true financial dominance in Miners Haven.
