Now you are in turf I know. I have the Telinga Pro 5. And I have both
the Twin Science and the DAT Stereo mic elements.
I'm not sure I'd agree all that much about the gain. The settings on a
recorder will be about the same for both. You might be able to sum the
two mics in the twin science, but I expect you would have some phase
problems as the audio path lengths would be different. You can sum the
two channels of the DAT Stereo with little problem and the central
subject is recorded by both channels.
The Twin Science, being a mono mic has the narrower acceptance angle
compared to the DAT Stereo. This gives the perception the gain is
greater. You have to maintain your aim more solidly on the animal with
the Twin Science.
The price is the same with either element from Stith. My recommendation
is the DAT Stereo if you are buying one element. It will mix to mono if
you need, and records a pretty nice stereo. I got both elements, but
rarely use the twin science, even for scientific recordings or
sonograms. The stereo is a real advantage when listening to recordings
with multiple callers. That's my workhorse mic, Telinga Pro 5 with DAT
Stereo.
On reach/sensitivity, I have recorded Barking Treefrogs from a distance
later measured as a mile straight line, With a pine forest in between.
They were very faint in the recording, but easily identifiable, there
were only about a dozen of them. I frequently pick up various frogs from
considerable distance and use the Telinga to zero in on them. That
distance with Barking Treefrogs is not that unusual. At that distance
you will not hear them without the Telinga. It is not uncommon in the
survey recordings for me to be recording good sounding recordings from a
quarter mile or so.
On the other end of the scale, you can work quite close with the
telinga. It does not easily overload, even out in frog chorus settings
where it's painful to be out without ear protection. I also often used
it pretty close in the survey work, there for picking out individual
frogs from the general din. Closest I've used it was 3', but there
primarily as the reflector helped to shield the mic from several nearby
noisy air conditioners.
These elements are made to match the telinga, I doubt doing any better
with add on mics.
