TEC-HRO sidewinder is a holder for Scatt-sensors which can be mounted on the rail for the rear-sight (also at the front-sight-rail- if it is Anschütz, Feinwerkbau or Bleiker!).
With the “sidewinder”, the center of gravity of the weapon remains almost the same when using Scatt and you do not influence the barrel vibration as it is when you attach the sensor to the barrel with the steel tape supplied by Scatt.
The use in performance centers has confirmed the product as “very good”!
(delivery without Scatt-sensor!)
