Stalker I SDR Stationary Directional Radar Speed Gun

The Stalker I is an economical law enforcement radar suitable for many speed enforcement applications. Its die-cast waterproof case is rugged enough for motorcycle duty, while the backlit rear display is adjustable for all lighting conditions. Digital Signal Processing enables Faster Speed tracking and target direction sensing. The rechargeable battery handle provides many hours of service between charges.

Direction-Sensing Technology
The Stalker I SDR, Stationary Directional Radar, is the ideal choice for speed enforcement. Available in models with and without Fastest Mode Tracking, both employ patented direction-sensing technology. Its die-cast metal case is waterproof to a depth of 2 feet, yet it is smaller and lighter than most hand-helds.
Backlit Rear Display
The 3-window backlit display presents an intuitive user interface with clear messaging and control buttons. Its LCD window displays the Strongest Target, Fastest Target (if enabled), and Arrows Icons indicating direction of travel for both target types.

12-Month Warranty
Both models - Stalker I with Fastest Mode (828-0002-00) and without Fastest Mode (828-0001-00) - include a high-capacity Li-ION battery handle, desktop battery charger, tuning fork, operator manual, and quick reference card. Each is warranted for 12 months.
