Eyeball Accuracy V2

Do you feel you have lost your sense of proportion or are simply looking for an upgrade? Many everyday estimates are still made with old formulas like π × thumb. These formulas usually lead to gross estimation errors that can become dangerous in practice. A few examples: “I reckon I can jump down from here without breaking anything”, “the bridge isn’t that low, we’ll fit under it easily” or “the police will never catch us, we must have a 2 km head start”.

With the certified Etel-Tuning Eyeball Accuracy you can easily re-check your estimates in future and make standards-compliant guesses.

The Etel-Tuning Eyeball Accuracy V2 puts the factory-fitted eyeball out of its misery.
