Harry Jones 25/06/2007 19:17:25 | I am interested in a decent pair of 10 x 50 binoculars. I have a pair of compact Nikon zoom 8-24 x 25s in mint condition which, if possible, I should like to exchange.
Is this a possibility? Harry Jones |
eebc - Jamie. 26/06/2007 09:33:17 | We do not sell any second hand products, so offer no part exchange service.
There are some very good 10x50 binoculars around at the moment, have a look at the Helios, Optical Hardware and Leupold products. |
KIA Airport 04/11/2008 15:16:11 | Can you please explain what the twilight measurement signifies / denotes |
eebc - Chris 04/11/2008 15:19:55 | We have tried in the past to drop the Twilight Index from our specifications, however due to the large amount requests for the figure, we have had to reinstate it.
Twilight Index is the square root of the magnification times the obective lens size. e.g. 10x50 = 500 the square root of 500 is 22.36. Obviously this takes no account of optical quality of the lenses. Better lenses and better coatings allow for a brighter image. It can also be only used to compare like-for-like magnifications. A 10x25 (15.81) has a lower value than a 10x50 (22.36) so the image on the 10x50 would be brighter and the binoculars would be better in low light. However, this is more or less common sense, a 50mm objective lens allows more light to go through it than a 25mm lens! Hope this makes sense!! |
geoff 09/11/2009 14:07:18 | im looking for a decent pair of binoculars mostly for going horseracing please advise |
eebc - Jamie 09/11/2009 14:48:45 | Generally a magnification of between 7 and 10 times is recommended for horse racing.
The best binoculars are the Zeiss 8x56, which we sell quite a few of to race goers. The Helios 10x50, the Opticron Countryman MC 10x42 and the Visionary 10x42 models also seem to be very popular for horse racing. |
don reddell 17/04/2010 12:07:16 | We are going to British Columbia in September, And would like advice on which Bino`s are suited, we will be in forestated surroundings and hope to see Grizzly Bears |
eebc - Chris. 20/04/2010 10:29:00 | Thank you for your enquiry.
We have sold a lot of binoculars to people who have took them to the rain forests, most of these have been either 8x42 or 10x42 roof prism binoculars. The roof prisms make them a bit smaller and easier to carry, whilst the 42mm objective (front) lenses allow for a good bright image under the forest canopy. Having never been to Canada (unfortunately) I was assume similar conditions in their forests. I would suggest having a look at the Visionary Freebird binoculars, available in both 8x42 and 10x42 and should suit the bill quite nicely. |
