About

Outfitted research and guiding teams with durable watches; tracks firmware support history to avoid dead-end platforms.

Core Beliefs

Ownership means control; buy tools you can keep using and moving.

Background

A field team once lost two days waiting for a proprietary charger shipped to a remote base. Since then I grade kits on cross-compatibility and support windows. Standard cables, exportable files, and real parts availability saved us money - and let the work continue while competitors stalled.

Perspective

I favor long support cycles, replaceable parts, and open data policies over novelty.
