Compact, easy to read computer, but a backlight would make it even better

Blackburn’s Atom 4.0 is not a bells 'n’ whistles, all-singing and dancing computer for those who want to scrutinise every moment of their training runs, or indeed bore their riding companions, friends and family to tears. On the contrary, it’s a pared to the essentials, slimline unit with uncluttered display for racers needing a combination of pinpoint accuracy (Speeds measured in tenths of a kph/mph) and crystal clarity. That said; current speed, average speed, maximum speed, trip distance, total distance, 12/24-hour clock, and battery life indicator are pretty comprehensive and the build quality’s top notch too.
The Atom employs cable ties for the top mount, which might’ve seemed bargain basement a few years back but assures a genuinely universal fit on standard and oversized handlebars and stem. In saying that, stem mounting works best with oversized ahead rather than quill or more sculpted designs such as the Woodman it's on in the pictures). Installation is pretty intuitive and takes ten minutes tops, although unlike some, the head unit will not communicate with other brands of fork transponder but the range is excellent and seemingly unaffected by tri bars/other handlebar furniture.
Setting the head unit and navigating through the functions is equally simple so long as you remember the right-handed button selects the modes while the left resets-this led to unintentional data erasure for the first couple of rides but quickly became second nature. Bijous dimensions (23x24mm display) over two lines belie the remarkable at-a glance-in-all conditions clarity. However, a backlight would’ve been a nice touch-especially in the mid winter gloom. More precise than most, it measures speed to the tenth of an mph/kph and proactively thundering past the ancient Magnox nuclear reactor, power lines and other areas of high interference failed to induce any of the once infamous 99.9mph readings and the lifetime warranty adds further peace of mind.
Bijous computer with extremely clear display and clever detailing but a backlight would earn it an extra point.

To Blackburn's usual high standards
Claimed 34g complete (our scales suggest 39g but impressive nontheless).
Very nice, nay intuitive to use.
Tell us how the product performed overall when used for its designed purpose
The Atom is almost everything you could want in a training/race companion. Light weight, simple, solid construction, clear display with just the right balancce of functions. Measuring speed in a tenth of an mph/kph offers greater precision than most and the pacer arrow really keeps you motivated.
It hasn't missed a beat-even riding through areas of high interference and the head unit passed my bucket of water test so should cope admirably with cross/winter and even mtb duties. The one thing I missed was a backlight- a real boon in winter.
