How to Choose a Snow Depth Sensor: A Field Buyer’s Guide

Deciding between snow depth sensors can be difficult. This guide was created to help you make the right choice for your application with confidence, covering the specs that actually predict field performance and how to tell a vendor’s marketing language apart from a documented, field-tested claim.

What’s inside:

  • A priorities matrix showing which specs are Critical, High, Moderate, or Low depending on your application (DOT, avalanche/backcountry, hydrology/research, or ski resort operations)
  • A breakdown of the six specs that actually matter, with the exact questions to ask any vendor for each one
  • A guide to reading a datasheet like a buyer, including the tricks vendors use to make a spec look better than it performs
  • A total-cost-of-ownership framework that goes beyond the sticker price
  • A vendor scoring rubric with a worked example, so you can compare vendors side by side before committing to one
  • A realistic evaluation timeline, mapped to actual months, so you’re not scrambling to get a sensor installed before the season’s first snowfall
