What’s the difference between the Petzl Micro and Nano Traxion?

[JefffromCanmore]

The difference is one wasn’t as good as the Edelrid SPOC, and the other was Petzl’s attempt to match the SPOC

Could you please clarify how they both work with petzl rad line which I thought was 6mm which is below the diameter rating for both devices?

[cernsb]

Still not entirely clear on what they're for though

@DaveSearle Dave- Question: I purchased the Petzl crevasse rescue kit and then later on I purchased the RAD line separately. Will the partner pulley component of the crevasse rescue kit also work with the RAD line?

[nckgrock]

what is the use case for the nano traxion?

[jacktaylor]

could this be used to make an adjustable lanyard for ropes access work?
