Accessories for Helios Fieldmaster
|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?
eebc - Jamie.
|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.
|Can you please explain what the twilight measurement signifies / denotes|
eebc - Chris
|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!!
|im looking for a decent pair of binoculars mostly for going horseracing please advise|

|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.
|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.
|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.
|hi we are going on safari and would like some help in choosing a pair of binoculars in the £60 bracket what do you suggest, many thanks steve|
eebc - Chris.
|Thank you for your enquiry, most people for use on safaris tend to use either 8x or 10x magnification, anything more gets a bit hard to hold still (particularly when clinging onto a Landrover)
The Helios 10x50 or the Visionary 10x50HD are a couple of nice 10x50 binoculars which would do the job.
However, most people prefer something slightly smaller to carry around with them, in which case the following are well worth considering: Opticron Oregon 10x42, or the Visionary Wetland 10x42
Another consideration is if any of the users wears glasses, the latter two models mentioned have twist up/twist down eyecups that allow a full field of vision both with and without glasses.
We have all of the above in stock at the moment.
|I have used a pair of Commodore 12x50 for last 20+ years but often thought about replacing them with higher capacity . But as I get into my 60 s feel my ability to keep the glasses steady unless supported by fence or car roof, would it be a waste of time investing in these 16x50?|
eebc - Chris
|The 16x magnification would certainly bring things a little closer.
A lot of people can hand hold them, but if you need to use a fence or car roof (a lot of people use car roofs!) for your 12x, then the extra magnification in the 16x would only make them harder to hold.
I would stick with your 12x for now, possibly in the future consider an 8x or 10x
