TwoNav Ultra GPS with Great Britain OS 1:50000 Mapping - Black

I could not get it to work. What little info on the screen was in Spanish and the box was also printed in Spanish, It would not respond to any button commands. A great disappointment. I sent it back on 6.08.18 and still not had my refund.Enough said!

I haven't had much chance to field test the device yet with the winter weather but having played about at home and in the local area this GPS is pretty simple to use. The small screen of this device is both a positive and a negative. It makes the device a really good size for carrying as it fits nicely in the hand and isn't too heavy. However, it doesn't make viewing the map all that easy and I would imagine this is even more difficult if attached to a bike. It would be more useful for a back up to a traditional map (ie when you get lost in the middle of nowhere) but it's pretty expensive for that when a smartphone would probably be just as useful.

TwoNav GPS instruction (or lack of) might as well be written in Klingon. No help from support. Its going back tomorrow!

Only a brief review, as the weather hasn't been good enough to really get out in the hills. I'll update later with more detail - but first point to note – this is very small for a GPS. Now, if all you want is co-ordinates, that’s fine. Unfortunately, if you want proper mapping, then it’s a problem. While the maps are detailed, the screen is simply too small for easy navigation, and the interface is sluggish and non-intuitive.Anyone who can afford this can afford a smartphone, which will do the same job much more effectively. It’s far cheaper to pay for an armoured casing and an external power pack than one of these.

This is a compact unit, a great size when you don't want to carry a bulky unit but want access to mapping, especially if it is going to used with the wristband. It's designed to be multi-use and is great for outdoor people who do a bit of everything. If you are mainly a cyclist, you might want to consider a bigger unit that would easier to see when mounted on handlebars and where size is less of an issue.A code is included for full UK maps (split into areas: Cumbria, North East, Devon and Cornwall, East Coast, Grampians, Midlands and North West, Scottish Highlands and Argyle, Scottish Islands, Scottish Lowlands, South- East, South-Central, Wales), once I worked out how to get them on the device (and they can't all go on at once, the size is greater than the capacity of the unit) all was fine with the maps.The OS 1:50000 mapping with topographical information is what sets this kind of device apart from just using a smartphone, but it is what makes it so expensive.I have only used it very briefly so far to test it out but the mapping positioning appeared accurate. I'll be testing it fully this weekend and will update my review with anything else that comes up during further use. The interface is a little clunky and it isn't particularly intuitive so I need to spend more time working out its full functions to be able to get the most out of it. There is a quick instructions guide that comes with it.The product is let down by a confusing website and software downloads. I seemed to have downloaded a map to the device but after waiting through the whole download process, no maps were actually on it. It's not intuitive at all!The company needs to get a better English translation of their website in place, the poor English makes it feel less professional and it is certainly reducing usability for an already confusing device and system.

First thing to note is that this is very compact for a GPS device - its rather smaller than I was expecting. This may be a good thing because it fits easily on the wrist which makes it very convenient to use, or it may be a bad thing if you prefer to have a larger screen.Its really multi-use - easy to use on the wrist for walking and easy to attach to your bike for biking use.It provides a mulitude of data from mapping to basic direction and distance. It also copes with ANT+ devices if you're into monitoring your heart rate etc.Relatively easy to get to grips with, but you will have to put some time in before operating it without thinking.Accuracy was very good.Some things you may not like:The location indicator is a big fat triangle - not really a good idea on a small screen. It really would have been more helpful to have a more petite arrow or something similar.It claims "Full GB ordinance survey 1:50000 mapping" - but do understand that you have to pay extra for the maps. Only one is included in the price which you have to choose from the website and download.It says it will function with all types of maps - well yes in a round about way. It wont, for example, use Garman maps in their native format - they have to be converted first.It appears that the manufacturer is a French company and the English version of the website has some rather poor English on it - something that doesn't really create the sort of professional image an item at this price level deserves.Overall a premium product that perhaps doesn't quite live up to its price but is still a very nice piece of kit that walkers, hikers, bikers and assorted others will find very useful
