Snarks are the best I've ever tried. ........I don't think they make a Banjo specific tuner..........................The SN-2 and 8 both have a mic and can be switched to either vibration or mic and will pick up the sound if it wasn't clipped to your headstock.
If all else fails, there's always tuning forks. Make sure you get the "all Instrument" version.

Thanks, I got the impression from online reading that the Snark was about the best bang for the bucks.
I asked if the SN5 can be used on banjos in a few different places and they all said yes so meanwhile I have ordered that. It does for mandolins apparently but I am never going near one of those.
The SN5 is chromatic and TBH not one of the Snark models actually says "for the banjo" like they do for the uke.
As for a mike, I have ones like that for my guitars and bass and they are in the spares box as I always use the plug in ones only.
We'll see what this Snark does; for the money I daresy it won't matter if it is no good - I can always attach it to my acoustics.
As for tuning forks! We only had that sort of thing back in the '60s and pitch pipes and boy was it a game. We used to get one guitar tuned then he would give us a note for the other guitars. I still have th pipes and forks from those days but they too are in the 'spares' box.
