Description
Haglof Sweden MD II+ Digital Tree Caliper
Advanced Diameter, Species & Height Data Tool
The Haglof Sweden MD II+ is a rugged, Bluetooth-equipped electronic caliper built for forestry, inventory, log scaling and environmental measurement. At Prospectors Supplies, we’re pleased to offer a tool engineered for field professionals who need fast, reliable collection of tree diameters, species, heights and log data—all with robust electronics, durable build quality and flexible data management.
Upgraded performance in the MD II+ includes an improved 120 MHz floating-point processor that delivers nearly three times the speed of earlier models, a high-capacity flash memory able to store over 100,000 measurement registers, and a backlit graphic display that’s easier to read in low light. The interface features intuitive icons, simple menus and support for naming up to 100 different tree species, making species coding, log ID, quality and height registration straightforward. Connect via Bluetooth® Low Energy (BLE 4.0) for live data transfer to mobile devices using Haglöf Link or MD II Com apps, or use USB for charging and file transfers.
The MD II+ comes with patented foldable jaws (SmartScale) for easier transport, durable electronics protected against moisture and dust, and a battery system designed to endure a full field week of work on a single charge. Whether you're in steep terrain, wet weather, or dense forest, this instrument has been built with the kind of reliability that helps reduce resupply trips and measurement errors.
