Formula Used
Target range before damp: base targeting range × (1 + target range bonuses ÷ 100).
Scan resolution before damp: base scan resolution × (1 + target scan bonuses ÷ 100).
Range factor: 1 inside optimal. Past optimal, 0.5 ^ (((distance - optimal) ÷ falloff)²).
Effective damp strength: base strength × script factor × skill factor × hull factor × rig factor × overheat factor × implant factor × resistance factor × range factor.
Stack factor: first module is full. Later modules use exp(-((position - 1) ÷ 2.22292081)²).
Final attribute multiplier: product of (1 - effective strength × stack factor) for each module.
Lock time: (40000 ÷ scan resolution) ÷ asinh(signature radius)².
How to Use This Calculator
Enter the target ship values first. Add its normal targeting range, scan resolution, and any positive bonuses already fitted or active.
Choose the number of dampeners and the script mode. Use the focused multiplier for a scripted module. Use custom split when your item window gives special values.
Add skills, hull bonuses, rigs, overheat, implants, resistance, optimal range, falloff, and fight distance. Press the submit button. The result appears above the form and below the header.

Advanced EVE Sensor Dampener Planning
Why the Estimate Matters
Sensor dampening is a planning problem before it is a button press. A pilot must know whether the target can still lock at the chosen range. The same pilot must also know how long a fresh lock may take after scan resolution is reduced. This calculator joins those two questions in one view.
Inputs That Shape the Result
The inputs start with the target ship. Enter its normal targeting range and scan resolution. Add any positive bonuses already active on that ship. Then add the dampener strength, script choice, number of modules, hull bonus, skills, rigs, overheating, implants, and resistance. These values create an effective reduction for each module.
Stacking and Range Control
Stacking matters. The first matching effect applies at full strength. Later effects are reduced by standard stacking factors. That prevents unrealistic totals when many dampeners hit the same attribute. The tool lists the final range multiplier, scan multiplier, damped targeting range, damped scan resolution, and lock time change.
Range control is also important. The calculator includes optimal range, falloff, and current engagement distance. Inside optimal range, the entered damp strength is treated as fully available. Past optimal range, the expected effect drops through falloff. This gives a practical estimate for long range fights, kiting, tackle support, and fleet screens.
Scripts and Lock Control
Scripts change the job. A range script focuses pressure on maximum targeting distance. A scan script focuses pressure on lock speed. An unscripted module spreads pressure across both attributes. The script multiplier is editable, so you can match your own fitting window, market item, or balance notes.
Use the lock-break note with care. A dampener does not work like a jammer. It can make an existing lock fail only when the final targeting range becomes shorter than the distance to the locked object. Otherwise, the target may keep that lock, while new locks become slower or impossible at range.
Planning Better Runs
For planning, run several cases. Test one dampener, then three. Compare scripted and unscripted modes. Add resistance for capital or special states. Export the result when you need a doctrine note or a quick briefing table. The goal is not guesswork. It is a clear estimate before the fight starts. Small changes can decide whether a hostile tackle, logistics wing, or sniper platform stays useful under pressure today.
FAQs
What does this sensor dampener calculator estimate?
It estimates final targeting range, final scan resolution, and lock time changes after sensor dampening. It also adds stacking penalties, script focus, range falloff, resistance, and bonuses.
Can this calculator match any module item?
Yes. Enter the damp strength from your item window. Then adjust the script multiplier, skill level, hull bonus, rigs, overheat, and resistance to match your fitting.
Why is there a stacking breakdown?
Multiple effects on the same attribute do not apply at full value. The breakdown shows how each later dampener contributes less to the final result.
Does a dampener always break an existing lock?
No. It mainly reduces lock range and scan resolution. An existing lock may break only when the damped targeting range becomes shorter than the current distance.
What does scan resolution affect?
Scan resolution affects how quickly the damped ship can lock a target. Lower scan resolution means a longer lock time, especially against smaller signatures.
What should I enter for signature radius?
Enter the signature radius of the object the damped ship is trying to lock. Use your ship, drone, or expected target size for the scenario.
Why include optimal range and falloff?
Electronic warfare pressure depends on range. The calculator keeps full effect inside optimal and lowers expected effect through falloff for distant engagements.
Can I export the result?
Yes. After calculation, use the CSV button for spreadsheet work. Use the PDF button for a simple report that can be saved or shared.
