About

Hardware-minded trail runner who builds test loops and publishes open GPX datasets comparing drift, lock times, and smoothing.

Core Beliefs

If a watch can't hold a line under canopy, it's decoration.

Background

A squall erased the ridgeline on a winter traverse. With visibility gone, we looped back to the last solid fix and followed the cleanest breadcrumb through scrub. The dual-frequency unit held a tight line; the others wandered. That auditability—track over hype—got us off the shoulder before dark.

Perspective

I rank watches by off-grid track fidelity and positional stability.
