jeffp, I use an electronic tuner for my 36 string Celtic harp, my fretted dulcimer, and my guitar. I won't tell you what kind of tuner I use (it's so old, there must be a lot of better ones out there), but I do suggest that you buy one of those clip on attachments so that your tuner can be linked to one of the soundholes at the back. Clip it on, and you'll be able to tune with other instruments and voice talking or singing in the background. Otherwise, it's too hard to get the tuner to register the sound properly, accurately or quickly. Before I got this device, I would have to arrive at song circles way in advance to try to tune my harp without the chatter and tuning of others in the room. Now, I can tune so quickly, and, as others have said above, enjoy the music.
