Does this answer your question? [what are the minimum number of micro/hydro-phones needed to perform 3d tracking?](https://bioacoustics.stackexchange.com/questions/74/what-are-the-minimum-number-of-micro-hydro-phones-needed-to-perform-3d-tracking)

Is this a pamguard question? It has a pamguard tag. Should it?

Hi @dickson! Your question is very vague, and there is a fair amount of research on this topic available. Please show that you have made an effort to answer this question yourself using traditional research techniques. This will also help narrow the focus of your question.
