Red oled with ballistic! - Astra Optix OTX2400B Laser 6x21mm Rangefinder Monocular

This one has Red OLED display, so the display is easy to read under very dark environment. When hunting at sunset period, it is very useful! Also, I don't need to use blue tooth or any connection, the ballistic is build-in, as long as I choose the group, it will automatically show me the holdover value. This is very helpful!
The Ranging distance is 2400 yard, so it is enough for almost every target I need to know the distance! The unit is very fast in response as well!
