The Hawke Universal Balance Plate (Model 64105) is a mechanical mounting accessory designed to correct the center of gravity for spotting scopes and optical setups mounted on standard tripod heads. When digiscoping adapters, cameras, or heavy accessories are attached to an optic's eyepiece, the resulting rear-heavy weight distribution can cause tripod head droop and strain pan-and-tilt mechanisms. Constructed from aluminium with a matte black finish, this balance plate provides a linear adjustment track to shift the mounting point, reducing mechanical torque and eliminating image vibration during high-magnification observation.

Key Features

• Linear Adjustment Track: Provides approximately 70 mm of continuous forward and backward sliding range to fine-tune optical balance.
• Secure Locking Mechanism: Features a sliding 1/4"-20 male thumb bolt with a knurled lock-nut to clamp optics firmly in place once balanced.
• Universal Base Interface: Integrated 1/4"-20 threaded socket on the base mounts directly to standard photographic and shooting tripod platforms.
• Lightweight Metal Construction: Weighs approximately 0.3 lb (136 g) to minimise added bulk on portable field setups.
• Passive Mechanical Design: Requires no batteries, external power, or electrical connections for operation.

Who is the Hawke Universal Balance Plate for?

• Digiscoping photographers — Corrects rearward weight bias by using the 70 mm sliding adjustment track on this universal balance plate to re-centre spotting scopes fitted with heavy DSLR, mirrorless, or smartphone camera adapters.
• Target shooters and hunters — Mounts standard 50 mm to 85 mm spotting scopes via the 1/4"-20 threaded socket and bolt system to eliminate tripod head droop and reduce pan-tilt strain during high-magnification viewing, while adding only 0.3 lb (136 g) to the field kit.

Less suitable for: Tripods utilizing 3/8"-16 mounting studs without a separate thread adapter, as well as oversized multi-kilogram telephoto camera rigs or precision rifle chassis systems that exceed single-screw torque limits and require dedicated Arca-Swiss balance rails, multi-point barrel supports, or Picatinny mounting plates.
