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 whatever 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.

Which BCA packs are the Stealth 240 and Stealth 270 compatible with?
The BCA Stealth 240 and Stealth 270 avalanche probe models are compatible with all BCA Stash backpacks and Float avalanche airbag models.

Which BCA packs is the Stealth 300 compatible with?
The Stealth 300 is compatible with all BCA Stash backpacks and Float avalanche airbags – with a few exceptions. The Stealth 300 fits in the designated sleeve inside the tool compartment of the Float 42, Float 32, Float 27, Float 25 Throttle and Float 22. The Stealth 300 fits in Float 8 but only at an angle and we suggest one of our smaller probes for this pack.
