There's no altimeter in the Venu Sq and that does mean that it's not as accurate with elevation change as some of the Forerunner devices are on one of our workouts the Venu was as much as 80m elevation out, as it's drawing this information from GPS data rather than a dedcated sensor.ДЄt this price, and positioned as a lifestyle watch, that is of little concern, because you'll still get accurate speed and distance results from it, which for runners, walkers, riders, or whatever it is you're doing, is the most important thing. We tested the Venu Sq alongside a handlebar-mounted Edge 830 bike GPS computer, with close results on the GPS trace. GPS aquisition is then fast and the results are accurate, occasionally drifting off the line a little when under tree cover, but generally speaking, very good. You can select the sports you want on your favourites list, so picking cardio, running, cycling, or whatever else, is easy enough.

Push the Sq's top button and you'll be taken through to sports tracking proper, where the GPS will fire up and you'll be shown stats specific to your sport. Reminders will pop-up to tell you get up and get active - just like many other devices out there - which can get a little irritating throughout every day, but you can turn them off. You'll get 24/7 monitoring of things like steps and your activity, with heart rate tracking and even the option for things like water intake. Features, functions and performanceДЄs this is a Garmin device, it's no surprise to find that the mainstay of the Venu Sq's functions are based around fitness tracking. Head out to exercise and you get 14 hours of GPS tracking, so each hour takes about 8 per cent of the battery according to Garmin's specs - which is close to our experiences wearing the watch out on long bike rides.

That can also include some workouts, but this is a device you can realistically wear through the night and the day for the best part of a week without having to charge. Garmin says that the battery will last six days when used as a smartwatch - and that figure rings true in our use. It's not quite as convenient as a fitness band, but certianly less intrusive than some of Garmin's chunky Forerunner devices if you're planning to wear it to bed. It's comfortable to wear with enough stretch in the silicone strap to allow for expanding wrists when exercising, but also pretty comfortable to sleep in too - should you wish to track your sleep patterns. That brings a lifestyle feeling to things, much less sporty and a little more subtle. The Sq is a light and compact watch, which is likely to be more popular for those with smaller wrists thanks to the overall dimensions.

The straps are 20mm wide, featuring a quick release spring clip like many other Garmin devices, so it's easy to swap the straps around, with Garmin selling a range of different styles, or there's plenty of third-party options too. Two buttons sit on the right-hand side for control, used in partnership with the touchscreen, while on the rear is the connection port for charging, along with the raised Elevate heart-rate sensor.
