What is your Alternate Camera?

Most of you on this forum would likely have a Pentax DSLR as your Primary camera, you may even have a Pentax DSLR as your secondary camera, but what is your alternate camera, one that is very different in either form or function from your main Pentax.

My main cameras are a K5 and K5II, with a K20D as backup, but my alternate camera is a GoPro Hero 3 Black edition. Its role is to go places that my DSLRs cannot.

So what are your alternate cameras?
