Haglof Sweden T4 360° Adaptor

Haglof Sweden T4 360° Adaptor

The Haglof Sweden 360° Transponder Adapter attaches to Plot Centre Staff or a monopod and works together with a compatible transponder (such as T3 or T4) to enable full-circle (360°) ultrasound measurements with Vertex rangefinders. Available through Prospectors Supplies, this adapter transforms your setup into a tool capable of circular sample plot work, giving you accurate distance readings all around the transponder without having to realign or reposition for each measurement.

Using the adapter, the ultrasound signal is spread in a full 360° radius, allowing walk-around measurements of plot boundaries or vegetation without needing line-of-sight in every direction. It simplifies the workflow for forest inventory, ecological sampling or any project that uses circular plots. The adapter is built to the same durable standards as other Haglöf accessories, made to withstand field conditions, resist wear and simplify measurement processes rather than complicate them.

Key Features

• Enables full 360° sweep measurements with Vertex rangefinders when used with compatible transponder (T3 or T4) and Plot Centre Staff or monopod.

• Simplifies circular plot boundary measurement, enabling all-around coverage without needing multiple setups.

• Compatible replacement or upgrade for existing adapters; also works as an accessory to enhance functionality.

• Built from robust materials for field durability and consistent performance under rough or wet conditions.

• Lightweight, easy to attach and detach, designed to fit seamlessly with other Haglöf measurement accessories.

Applications

• Forestry & ecological sampling where circular sample plots are needed

• Vegetation and understorey surveys where full surround measurement improves accuracy

• Research work that requires reliable, repeatable distance readings around a fixed reference point

• Utility line clearance or restoration projects where areas around a centre point must be mapped
