Vanguard is an international optics company founded in 1986 with over 1,000 employees worldwide. As well as binoculars and telescopes, they have also marketed high quality accessories for the sports optics industry. With a manufacturing and design headquarters in Myanmar, they offer an extensive range of binoculars from entry-level to upper mid-priced models. In this review, I’ll be discussing my experiences with an Endeavour ED II 10 x 42 binocular. This is a second generation ED binocular, bridging their simpler ED and more sophisticated ED IV models. Vanguard state that the ED glass elements used in their objectives are sourced from Hoya(Japan), but are assembled entirely in Myanmar, before being distributed to stores across the world.
I purchased the binocular with my own funds for £280 delivered to my door. The instrument arrived double boxed and came in a very attractive white storage box containing the binocular, a very nicely designed zipped closed logoed carry case, a padded neck strap, rubber ocular and objective lens covers, which can be tethered to the binocular, a lens cleaning cloth and an instruction sheet in many languages.
The Vanguard ED II 10 x 42 is an impressive looking instrument, sporting a high quality Magnesium alloy open hinge design, with a black pebbled rubber overcoat that has a texture more akin to bonded leather than the usual rubber-looking substrate offerings on most other models I’ve sampled. Weighing it at 770g, it is quite hefty as 10 x 42 binoculars go, but still nowhere near the 850g weight of some of ultra premium models now on the market.
The instrument feels very solid and secure in the hand. On its underside, two thumb indents suggest a place for you to properly hand old and balance the binocular. The instrument states “made in Myanmar” and has a serial number to help identify the batch and date of production.
The objective lenses have immaculately applied anti-reflection coatings and are very deeply recessed to cut down on stray light, dust and rain.
The binocular has a number of notable features compared with many mid-priced instruments that I have tested in the past. For one thing, the right eye dioptre is lockable. You simply push the ring up, rotate it to your desired position and then push it down to lock. It works quite well but I did notice a bit of play in it. The ring itself wobbles when a bit of force is applied and to be honest, I would have been perfectly happy with a regular non-lockable dioptre ring if it offers a bit more rigidity.. The ED IV models from Vanguard offer a better solution in this regard.
The central focus wheel is covered in a highly texturised rubber for excellent grip. Rotation is exceptionally smooth, taking just over one revolution of the wheel to go from one extreme of focus to the other. It is also remarkably fast, taking just three quarters of a revolution to sharply focus on the vast majority of objects. This makes it especially useful for birding, where rapid focus changes can be important, but I found it to be, well, a little too fast. You can easily overshoot the focus wheel if you’re not used to it, so this could be a bit off-putting for some users. Personally, I would have been happier with a slightly slower focus but having said that, it’s all about getting used to the binocular; so, in and of itself, a super-fast focuser is certainly not a deal breaker.
The twist-up eye cups are metal-over-rubber and have two intermediate positions. Fully extended, they hold their positions very well indeed. The generous eye relief of 19mm makes it very comfortable to use with glasses(tested by yours truly), where the entire field can be reliably imaged. Another nice touch about these eye cups is that they can be unscrewed when they wear down or break. Vanguard will be happy to send you replacement cups should you run into a spot of difficulty. The binocular can also be mounted to a tripod or monopod for ultra stable viewing. Simply unscrew the V-logoed screw on the front of the bridge and you’re in business.
Conducting the flashlight test on the Vanguard showed a good clean image; internal reflections were very minimal with no discernible diffused light indicative of good, homogeneous glass through the optical train. It did show a rather prominent diffraction spike though that was also observed at night when I turned the instrument on a bright sodium street light.
Conducting further daylight tests revealed a very sharp image with lots of contrast and excellent control of glare. Indeed, the Vanguard Endeavor ED II 10 x 42 showed better control of veiling glare than my Barr & Stroud 8 x 42 Series 5 control binocular.
The view is impressively wide for a 10 x 42 instrument – 6.5 angular degrees. What’s more, the Vanguard enjoys a very large sweet spot. Indeed, it’s edge of field correction is excellent, especially considering its modest retail price. There is very mild pincushion distortion near the field stops . Colours are naturally presented and chromatic aberration is pretty much non existent. Indeed I could only detect a trace of lateral colour at the edge of the field. All in all, the optics in this binocular are well above average, a fact that I was able to confirm by borrowing a first generation Swarovski EL Range 10 x 42 from a fellow villager. To my eyes, the views were very comparable in bright sunny conditions with the Vanguard having a slightly wider field of view.
Only when the light began to fade late in the evening did I begin to notice the Swarovski beginning to pull ahead. At dusk, near local midnight here in Scotland, the greater light transmission of the EL Range was very obvious, with tree branches located at a distance of 50 yards or so away being more easily seen than with the Vanguard. This is consistent with an allbinos review conducted on the Vanguard Endeavor ED II 10 x 42, which revealed a light transmission of only 80 per cent. Another low light test using my Barr & Stroud Series 5 8 x 42 also showed a significantly brighter image than the Vanguard but this could well be attributed to its larger exit pupil (5.25mm versus 4.2mm) kicking in during these low light conditions.
Notes from the Field
The close focus on the Vanguard Endeavor ED II is very noteworthy in that it focuses down to about 1.5 metres. I could sharply focus my walking shoes, which is more than I can say for many other 10 x 42s I have had the pleasure of using. Depth of focus is fairly shallow though – an expected result given its 10x magnification and roof prism design. Focusing is super fast on this unit, but I was slightly anxious about turning the focus wheel near the end of its travel. A tyro could easily turn the wheel too far and so damage the focuser. The lockable dioptre ring worked well in all situations. It remains tightly in place, so no worries there.
Because of the super fast focus wheel, I deemed it expedient to set the dioptre setting while the binocular was stably mounted on a tripod. After all, you need a stable view in order to achieve optimal image sharpness in both barrels.
The open bridge design of the Vanguard makes it very easy to handle, even with one hand. You can wrap your fingers round the barrels of the binocular which allows the user to get a slightly more stable view at 10x. The padded neck strap accompanying the Vanguard Endeavor ED II is of good quality but is a bit too long for my liking. Indeed, I often thought about attaching another shorter strap while making my tests.
I do love the padded case supplied with the Vanguard. With its eye-catching colour logo, padded interior and its ability to be zipped closed, I think it’s one of the most thoughtfully designed binocular cases I’ve personally encountered. A very nice touch!
The Vanguard Endeavor ED II 10 x 42 offers a lot of bang for the buck. Optically, it serves up very nice images indeed and will hold its own against instruments costing far more. Indeed, my main take home point about this instrument is that as one invests in more expensive models, it is mainly the mechanical and not the optical properties of such an instrument that one is buying into. More expensive binoculars will have greater light transmission(of the order of 90 per cent) but those advantages can really only be seen at dawn or dusk. But if you do all of your glassing in broad daylight, that light transmission advantage will be of little importance to you. So, something to bear in mind.
I also get the impression that Vanguard care about their customer service and one can email an employee of the company – see the link provided above to start with – if you encounter any problems with your binocular. If you’re in the market for a sensibly priced instrument in this aperture class that will live up to the rigours of life in the great outdoors, then I would strongly recommend it. You’re not likely to get much more for an investment under £300 UK.
