 The advantage of this method is that it is less prone to outlier points.  The disadvantage is that it is hard to aim at thinner walls.<br><br>
 For tube walls with high-reflectivity with burrs or saw marks, we recommend either a coating (see below) or the most precise [[End-Scan Using End Targets]].

 When scanning the end walls of highly reflective tubing with striations like shown in the image on the right, it is better to either cover the end with a coat of Maganaflux, Dynaflux, foot powder spray, white marking paint pen, or cover it with an end target to avoid outlier points.<br><br>
 The image below shows an end target plastic label attached to the end of the same tube.  In this case, there are no striations visible.<br><br>

-We recommend this for increased precision where it is possible to strike the end wall.  high-reflectivity and burrs are not an issue on the end wall of the tube.  The End Wall method is also very useful for thicker wall tubes.
