    SFL30 comments and experiences

    I find the weakest points of my SFL 10x30 are CA control and blackouts. It's still good enough but I would prefer better for both.

    new tiny Zoom F3 recorder

    Yes and no - it certainly is a good recorder. 32bit wavs are useful as is the 6s pre-record option. Also it seems completely immune to RFI. Sound-wise I must say I was expecting more. There is hardly any difference compared to a Olympus LS-3 with PIP in a similar parabolic setup which also has...

    Measures V2 Foldable Dish

    IIRC the depth and therefore focal points of those dishes are different so I would not recommend swapping dishes in between those brands (unless you can adjust the focal point with the mic setup).

    new tiny Zoom F3 recorder

    To add a data point regarding battery runtime of the Zoom F3, I get about 5,5 - 6,5 hours of constantly pre-recording or recording with this setup: one 24V phantom powered microphone with 4x PUI AOM 5024 mic capsules in parallel second XLR deactivated no headphones display light off after 1...

    Zeiss SFL 8x30?

    I can no longer find the specs (or photos) on the two sites that have been mentioned in the first posts. Does anyone remember the minimum focusing distance of the 10x30?

    Thermal "spotting scopes" - the experience thread

    From what I have read, the Pulsar Helion XPs are the state of the art thermal imaging scopes right now. Looking forward to future devices and prices coming down someday. I do bat surveys from time to time but with a bat detector only I always feel a bit detached from the action. Yes, I can...

    Thermal "spotting scopes" - the experience thread

    Very interesting, Vollmeise! Can you share your experiences with summer-time use? Also did you give it a try for other species like bats?

    Handbook of Western Palearctic birds

    Judging from the NHBS preview pages Scottish Crossbill is treated as a subspecies of Common. Maybe that will sell a few copies less? ;-)

    Problems with Kowa Europe

    I have seen specks in at least four Kowa scopes or eyepieces (only 20-60x) of the TSN-88X series. They are usually visible at the lowest magnification only but nevertheless distracting, especially if you do a lot raptor watching. I was lucky as the speck in my eyepiece disappeared after some...

    Corsica - October

    I walked the GR20 in late September. I saw all the endemics, even Moltoni's Warbler (but just one female). Corsican Finch is easy up in the mountains and Marmora's Warbler was locally common, too. The Nuthatch can be found in most old forests above 1000m. For all of these species knowing the...

    Mavrokolympos Dam, Cyprus

    Hi, I've been there once. Fresh water lakes can be very attractive for birds in Cyprus but this is a reservoir with varying water levels, so the shores are quite degraded - no special water birds to be expected there. Typical cypriot birds in the surroundings but again, nothing special. There is...
