[2025-10-02T03:39:27.524913] [PI reasoning] **Exploring apex locator accuracy**

I’m looking at the accuracy of apex locators, particularly with open apex situations. It seems there isn’t much direct evidence on this, so I want to delve deeper. I’ll search for information specifically about "open apex electronic apex locator" to gather more details and clarify any uncertainties. Let's see what I can find!
