Overview

The KILO3K is the value story in this category. It is small enough for a bino harness, powerful enough for practical rifle hunting, and smart enough to produce MOA or MIL windage/elevation data through Applied Ballistics Ultralight. The onboard solution is limited compared with full AB Elite systems, but the price makes that trade-off easy for most hunters.

Key Features

  • BDX-U, BDX-X, AMR, LOS, and Archery range modes
  • Onboard temperature, pressure, and humidity sensors
  • Five target modes including first, best, last, fog, and extended range
  • HyperScan with four range updates per second
  • Red OLED display with ambient brightness adjustment

Pros

  • +Best ballistic feature set near $350
  • +Excellent deer and tree range numbers for the money
  • +Pairs with SIG BDX sights and external devices
  • +Lightweight enough to carry all season

Cons

  • Applied Ballistics Ultralight is not the same as a full AB Elite workflow
  • SIG ecosystem is most valuable if you use BDX-compatible gear
