Very good in low light, so good for deer stalking and running shots at driven game.It was the common continental reticule on the run up to the war. Fine crosshairs are no good at all, once the light starts to go. Nowdays they have illuminated reticules, so the thick No.1 reticule is a bit redundant, however still favoured by older continental deer stalkers. I prefer the No.4 reticule myself in 8 x 56 flavour
