Re: Recording sap flow and beetles

["Dan Dugan" dandugan_1999]

When I clipped a Telinga Clip-On to a stump I got a recording of gnawing in=
side that I didn=92t expect. The flat tab of the clip was inserted in the s=
hrink-wrap sleeve where the wire exits, and I suspect the metal tab of the =
alligator clip was contacting the shell of at least one capsule.

Also JrF makes piezo contact mics.
