The Arken Targetlock TL3000 Weapon Mounted Ballistic Laser Rangefinder in Flat Dark Earth (FDE) delivers real-time elevation and windage firing solutions directly from the rifle platform. Designed to mount onto standard Picatinny rails or ring-mounted diving boards, the unit measures 88 mm × 56 mm × 34 mm and weighs 7.5 oz (213 g). It integrates an onboard DNT Ballistic Engine capable of storing up to 6 custom ballistic profiles, allowing standalone operation without a paired mobile phone in the field. Powered by a single 3V CR123A battery, the unit features an internal visible green laser for optical alignment, an included wired pressure switch for remote activation, and onboard sensors that provide angle-compensated calculations with automatic screen orientation.

Key Features

• Long-Range Laser Ranging: Ranges reflective targets out to 3,000 yards (~2,740 m) and non-reflective game targets up to 1,100 yards (~1,000 m), with ±1 yard accuracy within 2,000 yards.
• Integrated DNT Ballistic Engine: Computes real-time firing solutions displayed on the device, eliminating the need to break shooting position or reference external charts.
• Hands-Free Activation: Includes a remote wired pressure switch connecting to an integrated port, allowing shooters to ping targets without altering their firing grip.
• Sensor Integration and Connectivity: Incorporates low-power 2.4 GHz Bluetooth for pairing with the DNT Ballistic App and external Kestrel weather devices, along with onboard inclinometers for real-time shot-angle calculation.
• Direct Picatinny Interface: Attaches directly to Picatinny accessory rails and diving-board scope mounts to maintain a low-profile optic setup.

Who is the Arken Targetlock TL3000 Rangefinder for?

• Precision Rifle Series (PRS) and NRL competitive shooters — delivers immediate firing solutions via an integrated ballistic engine and remote pressure switch without requiring the shooter to break their grip, adding only 7.5 oz (213 g) to the rifle balance.
• Extreme long-range (ELR) precision shooters — provides ranging capabilities out to 3,000 yards on reflective targets with an accuracy of ±1 yard inside 2,000 yards directly from a weapon mounted ballistic laser rangefinder.
• Long-range hunters — computes angle-compensated holdovers directly on the display for non-reflective fur targets at distances up to 1,100 yards, operating on a single CR123A battery without requiring an external mobile device.

Less suitable for: Soft or fur game targets extending past the 1,100 yards threshold, where high-output military-grade weapon-mounted rangefinders or tripoded spotter laser rangefinders serve the shooter better; or fast-action bush stalking, where the additional 7.5 oz (213 g) top-heavy rail weight compromises handling compared to a handheld pocket laser rangefinder.
