As the designer of the F-POD and the KERNO-F classifier I can say that the big difference is in dolphin detections - short broadband clicks. The detection rate goes up by a large factor, typically more than 3, even though the false positive rate has gone down. For porpoises and other narrow band high frequency species the increase in detections is much smaller.  The F-POD does have clock and knows its start and end times.

<p>My lab recently went to purchase some replacement C-PODs (made by <a href="https://chelonia.co.uk/index.html" rel="noreferrer">Chelonia Limited</a>), and were given the pitch up about upgrading to the F-POD.</p>
<p>Does anyone have any experience with these? Are they different? What are the practical points of upgrading? Is the data comparable to the C-POD?</p>

My lab recently went to purchase some replacement C-PODs (made by [Chelonia Limited](https://chelonia.co.uk/index.html)), and were given the pitch up about upgrading to the F-POD.

Does anyone have any experience with these? Are they different? What are the practical points of upgrading? Is the data comparable to the C-POD?
