For surveyors and site managers the tablet is the drawing, the camera and the notebook at once, and it is used a long way from the site office. The two things that decide the purchase are screen size and weight, and they pull in opposite directions.
What kills devices on survey and site work
- Weather. A survey does not stop for rain. The device is out in it for hours, not just for a dash between the van and the cabin.
- Dust and mud. Cutting dust, cement and wet clay get into ports and under screen edges, and a muddy glove across the glass scratches it.
- Drops onto hard ground. Off a scaffold lift, out of a cab, off a wall you were measuring from. Concrete and hardcore do not forgive.
- Being carried all day. A tablet in one hand and an instrument in the other for several hours is where weight and a strap stop being details.
- Glare. Reading a drawing in full sun is where a dim screen fails you.
What actually matters in a spec
Screen size and resolution. An A1 drawing on an 8 inch screen is a lot of pinching and zooming. The A10 has a 10.1 inch screen at 1920 x 1200, which is the difference between reading a plan and hunting around it. The W10 is also 10.1 inches but at 1280 x 800, the same resolution as the 8 inch A8. Our 8 inch or 10 inch guide goes through the trade off.
Weight on a long walk. The A10 weighs 680g and the W10 1197g, a difference of 517g that you will notice by the end of a site walk. The A8 does not list a weight. A shoulder strap or hand strap is worth having on any of them.
Sealing and drop testing. The A10 is sealed to IP68 and tested to MIL-STD-810H. The A8 is IP67 and lists no drop rating. The W10 is IP65, which covers dust and water jets but not immersion, and lists no MIL-STD rating. Our MIL-STD-810H guide explains what the standard does and does not tell you.
Brightness. The A8 is rated at 1000 nits, the A10 at 350 nits, and the W10 lists no brightness figure. If most of your day is outside in summer, that is a real point in the A8's favour.
Location. Measuring and mapping apps lean on the device's positioning. The A10 lists GPS, Galileo, BeiDou, QZSS and NavIC, the A8 lists GPS, GLONASS, Galileo and BeiDou, and on the W10 GPS is an option rather than standard. Check what accuracy your app expects from a tablet's own receiver.
Your software. Drawing viewers, snagging tools, PDF mark-up and most measuring apps run on Android or in a browser. Survey and CAD software that only runs on Windows forces the W10, which also brings Ethernet and HDMI for the site office. Check your own software on the device before buying a fleet.
What we would pick
For surveyors, site managers and anyone who reads drawings for a living, the Tuga A10 at £449. The 10.1 inch Full HD screen at 1920 x 1200 shows an A1 sheet without constant zooming, and 8GB of RAM with 128GB of storage, expandable to 2TB by microSD, copes with large PDF sets. It is sealed to IP68, tested to MIL-STD-810H, rated for -20°C to 60°C and weighs 680g in a 14.5mm body. The 8000mAh battery has quick charge, dual SIM 4G covers rural sites, NFC is built in, and the 13MP rear camera has a flash for photos in a riser or a basement. A hand strap is in the box. Two caveats: the screen is 350 nits, so in direct summer sun it is harder to read than the A8, and the battery is not listed as removable, so a long day leans on the car charger.
If your survey or CAD software only runs on Windows, the Tuga W10 at £649 is the one. It runs Windows 11 Pro on an Intel N100 at up to 3.4GHz with 8GB of RAM and 128GB of storage, and the ports are the point: HDMI for a site office monitor, RJ45 Ethernet for a wired network, plus USB-C and USB-A. The 5000mAh battery is removable, and it has NFC and a pogo pin dock connector. It is £200 more than the A10, and the trade offs are weight, at 1197g, and ratings: IP65 rather than IP68, no MIL-STD or operating temperature listed, and a 1280 x 800 screen. 4G and GPS are options, so confirm them when ordering. A version with a 2D barcode scanner is £729.
For a site manager who mostly snags, photographs and signs off, and only glances at drawings, the Tuga A8 at £379 is £70 less than the A10 and brighter outdoors at 1000 nits. It is sealed to IP67, has a removable 8000mAh battery, dual SIM 4G and a 13MP rear camera with a flash, and fits a van door pocket. It lists no weight, drop rating or MIL-STD rating, and runs Android 12, so check your snagging app supports it. If you kit out a whole site team, the construction page covers the trades side.
Accessories worth adding
A Shoulder Strap (£19) keeps the tablet on you and both hands free for the instrument, and a Capacitive Stylus (£14.99) makes mark-ups and snag notes precise. A Tempered Glass Screen Protector 2-pack (£14) is cheap insurance against grit. The Hand Strap (£24) is in the box with the A10 and W10 but not the A8. A Rugged Carry Case (£34) suits a tablet that lives in the back of a vehicle, and a Charging Dock (£49.99) for the site office fits the A10 and W10 but not the A8. The Vehicle Mounting Dock (£109) fits all three. Everything is on the accessories page.
Questions surveyors ask
8 inch or 10 inch?
If you read drawings for a living, 10 inch, and the A10's Full HD resolution is the reason to pick it. If you mostly photograph, snag and sign off, 8 inch, which is brighter outdoors and £70 cheaper.
Do I need Windows?
Only if a program you cannot do without is Windows only. Viewing PDFs, marking up drawings and most measuring and mapping apps run on Android. CAD authoring belongs on a laptop; if you need it on site, the W10 is the one to look at. Our Android or Windows guide has a five minute test.
Can we equip a whole team?
Yes. Bulk discounts apply automatically: 3% at 2 devices, 5% at 3 to 4, 8% at 5 to 9 and 10% at 10 or more, and you can mix models. See bulk pricing, or get in touch for a quote or a proforma invoice.
What if it fails?
Every device has a 12-month warranty and UK email support, plus 30-day returns and free UK delivery in 7 to 10 working days. For longer cover, the 3-Year Warranty is £65 to £89 per device, and business fleets of five or more devices on any model can ask for a Total Care quote, with a pre-imaged swap unit dispatched the same working day for claims accepted by 14:00.
