Celestron Trailseeker 8x42 Binoculars Review


Whilst many of us will instantly recognise and indeed associate the Celestron brand with astronomy, in terms of producing binoculars specifically designed for terrestrial uses, they are fairly new to the party.


However that is not to say they are beginners in terms of being able to produce a quality instrument for looking at objects on this planet: Not that long ago, I had the pleasure of testing and reviewing the Celestron Granite 8x42 bins, that went on to win the award for for the Best Birding Binocular that year.


Whilst they may have a different body design, from first impressions, these Celestron Trailseeker 8x42 binoculars remind quite a lot of the Granite's. Indeed as you will see later in the review, they share many of the same very impressive components, accessories and statistics that helped the 8x42 Granite win that award.


So considering that this Trailseeker binocular is much more budget focused and thus aimed at the more price conscious user, is already really impressive.


However to produce a quality instrument that also has a small price tag is very difficult to achieve because you have to make some sort of compromises along the way and even though many try, many get it wrong. To take a look at and see how well I think Celestron have done.


Sealed Body


These Celestron Trailseeker 8x42 Binoculars are described by the company as being "fully waterproof", which does mean that the body has been fully sealed, but they do not go on to specify a recognized standard or depth.


For most users this does not matter as it does mean that you can use them with confidence in even the worst weather conditions, just don't test them out in your pool! Also remember this sealed body also helps prevent even the smallest dust particles from getting into the system, which if you live in a dry area is just as important as waterproofing.


Nitrogen Purged


Celestron also state that these binos are "nitrogen purged", which simply means that during the sealing process, all internal air is sucked out and replaced with nitrogen gas. This dry gas and now moistureless internal offers a number of important advantages:


Firstly it helps prevent the internal glass surfaces from misting up, secondly it prevents corrosion and thirdly it stops mould from growing on the internal surfaces, something that many of us will have seen on very old pairs of binoculars.


Rubber Armored


Whilst the vast majority modern binoculars are armored, not all of the coatings are the same and sometimes these subtle variances in their materials and properties can add up to make a noticeable difference:


Apart from the diopter ring and a few small details, almost the entire exterior on the Trailseeker is has been rubber coated. Whilst it is quite thick, the rubber that they have used is very hard and thus the body does not have as much of a squashy feel about it as some. I personally like this as you do get more of a feeling of quality and whilst it does a better job of protecting the exterior from marking and scratching, you do get a little less impact cushioning with such a hard rubber.
