DN/ST - Total Energy Probe - for ST1 mounting adapters - Most Popular
This "V" style TE Probe is the latest and highest performance TE probe available. It offers very good Total Energy compensation. It is exceptionally good at accommodating horizontal air movement caused by horizontal gusts or yawing of the aircraft. This version is compatible with ST1 mounting adapters - which have been built into many sailplanes.

Here's a nice sailplane high-speed / low-altitude pass video which clearly shows a correctly mounted DN TE probe.
