What Our UK Customers Say
Absolutely brilliant for surveying old tenements. The 100m range is overkill for most rooms, but it's incredibly fast and much more reliable than my old Toolstation budget buy.
The Pythagorean mode is a game changer for estimating guttering jobs. I can measure the height of a house from the pavement. Saves me so much time on quotes.
Great bit of kit for the price. Only minor gripe is the beep is quite loud, but you can turn it off. Accuracy is spot on compared to my Leica.
Used this for a full kitchen renovation. The area function made ordering floor tiles so easy-no more over-ordering and wasting money at B&Q!
Solid build quality. I've dropped it once on a concrete floor and it's still working perfectly. The backlit screen is essential for dark loft conversions.
Very accurate for internal measurements. It struggles a bit in very bright direct sun in the garden, but that's expected for this price point. Excellent value overall.

At RockSeed, we believe that precision shouldn't be a luxury reserved for multi-national construction firms. Based in the UK, we've seen first-hand how traditional tape measures lead to costly material miscalculations and project delays. Our mission is to equip every British homeowner, surveyor, and decorator with the 'Pro-sumer' tools they need to work smarter, not harder.
Our flagship electronic distance meters are engineered to withstand the rigours of an active UK building site while remaining intuitive enough for a weekend DIY project. By focusing on essential professional features-like 100m ranges, Pythagorean indirect measuring, and robust data storage-we provide the functionality of high-end brands like Bosch or Leica without the premium price tag.
We are committed to quality and compliance, ensuring all our laser tools meet strict CE and RoHS standards. When you choose RockSeed, you aren't just buying a tool; you're investing in the confidence that every measurement is spot-on, every time. From the first floorboard to the final coat of paint, we help you measure once and get it right.
