What is the difference between an aluminum and carbon probe?
Carbon probes are lighter than aluminum probes but aluminum probes are more durable and are more suitable for every day use.

How do I choose the appropriate probe length?
You should choose your probe length depending on the depth of your snowpack. In a shallower Colorado snowpack, a Stealth 240 is sufficient. If you live in an area with a deeper snowpack or travel to areas that have deeper snowpack you should consider a Stealth 270 or Stealth 300. It is also important to make sure the collapsed length of your probe will fit inside the pack you are using.

What is the difference between laser etched and painted depth markings?
All BCA aluminum probes have laser etched depth markings while the carbon probe depth markings are painted on. The laser etched depth markings are more resistant to wear.
