Tom Lock ‘Series 1’ 8×42 Waterproof Binocular












Introducing the New Tom Lock ‘Series One’ fully featured 8×42 roof prism binocular.

Don’t be fooled by the cheap price – this is not a cheap binocular!

The binocular is a compact roof prism design ideal for the keen birdwatcher. The prisms are made of BAK-4 glass material which insures hi-fidelity colour rendition, important for birdwatchers where a slight difference in plumage colour can mean the difference between one species and another. Our lens surfaces are ‘multi-coated’, this ensures maximum light transmission through the glass, reducing light scatter, and results in crystal clear contrast rich images through the eyepiece.

The binocular is waterproof. To be called waterproof a binocular has to be able to be submerged in water one and a half metres deep for a period of three minutes without letting water enter the instrument. So if you drop your binocular in a stream or puddle it will survive. If you drop in mud, just wash it off, and you will never have to worry about getting caught in the rain. The binocular is also nitrogen filled so is also fog proof.

It’s rubber armoured body, not only makes the binocular easy to hold even in a gloved hand thanks to the dimpled finger panels, it also insures that it is protected from all but the most severe impacts – it’s at home in any weather and any terrain!

The binocular also feature twist up rubber eye-cups. These enable the user to get their eyes in the perfect viewing position whether or not they are wearing spectacles. The rubber surface protects your spectacles from being scratched in the process. Other nice features include the captive lens caps which make it much harder for you to loose them during the heat of the moment, if there is a must view opportunity it is very easy to whip off the lens caps in haste and then forget where you put them. For those who are determined to take them off, perhaps it’s windy and they keep blowing in front of the lens, it is easy to remove them completely and we have provided you with a pocket in the carrying case which is the perfect place to store them.

So how do we give you all this binocular for such cheap price. To find out our secret ‘Google’ Tom Lock Concept and be prepared to be pleasantly surprised! Buy wise –buy safe – buy Tom lock!
