DT;
The new one I received in the mail yesterday is the only snark I've had any experience with. I have a feeling that the 'accuracy' claim is pure advertising. My Korg CA-1 seems just as good. The key feature for me though WAS the new display. I can see it while it's clipped on to the headstock of my dulcimer without using my glasses. I do question the durability of the snark. The Korg is very robust (except for cement floors). I won't use the swivel on it much, I think it would wear quickly. The clamp does seem adequate.
I had trouble on occasion with background noise (tv etc.) registering on the Korg. The snark 'reading' vibes through the head stock may be a real advantage. Still new, I'll have a more objective opinion once I've used it a while.
