Emlid Reach RS4: No Frills, Just Fixes
You're looking at the sensible sibling. The workhorse. The Emlid Reach RS4 is a multi-band RTK GNSS receiver for the professional who needs one thing above all else: a reliable, centimetre-accurate fix, every single time. It doesn't have the flashy cameras of its RS4 Pro counterpart. It doesn't make coffee. It just connects to a frankly ridiculous number of satellites, compensates for your inability to hold a pole straight, and gives you the data you need to get the job done.
Why You Want It
Because you value performance over gimmicks. The Reach RS4 is built on the exact same foundation as the top-tier model, featuring the same powerful all-band GNSS engine, the same lightning-fast tilt compensation, and the same bomb-proof IP68 magnesium body. You're getting 95% of the performance for a fraction of the price. It's the smart choice for anyone whose workflow involves more measuring and less augmented reality. Your wallet will thank you, and your clients will never know the difference.
Features and Highlights
- Fast Tilt Compensation: A next-gen IMU that initialises in seconds. Measure corner points and stake out at awkward angles without obsessively checking a bubble level. Life's too short.
- All-Band GNSS Support: Tracks L1/L2/L5/L6 signals from every constellation worth mentioning. It gets a fix in dense woods and urban canyons where your phone can't even get a single bar of signal.
- Built Like a Brick... Outhouse: The IP68-rated magnesium alloy body is designed to handle a proper British Tuesday—sun, rain, mud, and then a bit more rain. It's tough enough for any job site.
- All-Day (and Then Some) Battery: With 16 hours of life as an RTK rover on a single charge, the RS4 will outlast your motivation to keep working. It charges via a standard USB-C, so you can top it up with a power bank if you're really pushing it.
