i m looking at a monocular for bird spotting when i m at work, want one that will fit in my pocket and not too expensive.

this one looks good to me as its waterproof and has bak-4 coated lens, is it a good choice? any other recommendations for similar price?

Thank you for your enquiry.

The Trailfinder monoculars are very good, both optically and physically. They are easy to use and have a good sharp image.

I have seen through quite a number of monoculars (probably over 100 different models) and for the price and size, these are the best I have seen. Most pocket monoculars tend to be 8x21 (or 8x20), with the Opticron being 8x25, it provides a much sharper, brighter image.

So, to give a one-word answer to your question "is it a good choice?" - yes.

We have them in stock, so if you are anywhere near Lincoln, come and have a look.

I am looking at the trailfinder II monoculars, to use whist walking looking for distant waymarks across a field, birds etc. would the 8x or the 10x be the best?

For distance the 10x just bring things that little bit closer, making them a little better than the 8x for looking across valleys and fields etc.

Admittedly, there is not much difference between the both of them side-by-side, but for your use, I would lean towards the 10x25.

I do quite a bit of sailing and have some Carl Zeiss binoculars for identifying navigational marks etc but I recently sailed with a guy who had a monocular and it seemed quite practical. Looking at this and the 10x model I wondered if you thought they d be suitable for a salt water environment as they re described as waterproof but you also seem to stock a higher price model which is called waterproof I think, so wondered if these were only waterproof in certain circumstances.

Also do they have somewhere to attach a strap, and does the diameter of the lens make a significant difference in the maximum range for viewing items, e.g. would a monocular help identify objects 1 - 2 miles away?

We have sold a number of monoculars to people who have been using them on yachts, most go for the 8x as it is a little easier to hold steady.

There is an international standard for "waterproof" it is something like being sprayed from all sides with water, so many gallons within a minute (or something like that). They are not "immersion" waterproof, where if held under the water, the pressure of the water would force its way into the instrument.

They come with a clip-on strap and this clips onto a lug on the monocular body.

The diameter of the lens does effect the image, the larger the lens, the brighter and sharper the image. Details can be seen more clearly through a larger objective lens, however, this makes the whole instrument physically larger.
