Oudie IGC recertify before sale??

I have an Oudie IGC that I got a couple years ago. I'm sort of selling off some of my aviation stuff (because I got a supercub and I'm going nuts with that)

My question is this. I know it had some sort of calibration that was included, and this is a requirement if you use the Oudie for badge and record claims.

Should I send it out for recertification before sale? Who does it?

I'm selling.. The Oudie. A long softie chute (2 or 3 years old. never repacked) and a stratus and Ipad mini setup.

Thanks for any insight. The internet is cool for casting a wide net to get answers. The oudie works pretty well for a 'club type' solution where you jump into different gliders that may not be equipped.
