Buying Guide

Battery Life

A PLB with GPS functionality can be a lifesaver in an emergency situation. Look for a device that can provide your exact location to rescue teams, as this can help them find you more quickly and easily.

Durability

Your PLB needs to be able to withstand the rigors of hiking and mountaineering, so look for a device that’s built to last. Consider a PLB that’s waterproof, shockproof, and able to withstand extreme temperatures.

Additional Features

Some PLBs come with additional features that can be helpful in an emergency, such as a flashlight or strobe light. Consider what additional features you might need based on your specific hiking and mountaineering needs.

Why Trust?

At Crave the Planet, I’m all about honest and relatable reviews of outdoor products. As a physical therapist, hut to hut hiker, downhill skier and mom, I’m constantly trying new gear to make my outdoor experiences more comfy and fun but with science in mind.

I’ll be real with you, I don’t do every outdoor activity. But, who does? I’m just a regular person who loves exploring the planet. Perfectionism is my enemy and I hope to help you ditch that vibe too.

My review process involves testing each product in real-life outdoor situations, but if it’s a really horrible day I’ll probably find a hotel in the valley. I’ll let you know what worked for me and what didn’t, so you can make informed decisions about your gear choices.

I don’t do sponsored reviews or take payment for my reviews. All comments are based on my personal experience. Sometimes I’ll test something and then send it back for a refund. Usually there’s a hefty fee. Bummer. So, if you’re looking for a relatable and honest take on outdoor gear, you’re in the right place.
