Point measurement techniques, notably hot-wire anemometry and laser doppler anemometry, have been pivotal in advancing our understanding of wall-bounded turbulence. Their distinct advantage lies in their ability to resolve smaller time and length scales, historically outperforming field measurements. As cutting-edge facilities like CICLoPE push the boundaries with increasingly higher Reynolds numbers achievable in laboratory settings, the smallest length scale in the flow further reduces, posing a challenge for the physical size of the probe/measurement volume. This presentation will provide an overview of the current state-of-the-art in point measurement techniques, delving into their capabilities, strengths and uncertainties. Moreover, it will explore the future prospects of these methods, particularly their potential at even higher Reynolds numbers.
