4G and UHF in One
A built-in 4G modem takes network corrections with your own SIM, and the 2 W UHF radio takes corrections from your own base.
4G Rover, UHF Base & E600 Controller

Complete Your Kit
Base-and-rover RTK with the best of both: the FJD Trion V10a rover has its own 4G for network corrections, and the V1t base station kit with a 2 W UHF radio covers the jobs where there's no coverage. The kit includes FJD's E600 controller with Trion Survey ready to use.
This kit puts the FJD Trion V10a rover kit and the V1t base station kit together.
Where there’s coverage, put a SIM in the V10a and work off an NTRIP correction service (a paid network, or Geoscience Australia’s free AUSCORS streams). Where there isn’t, set up the base: it sends corrections over its 2 W UHF radio, and fJD rates the link at about 5 km in normal conditions (3–8 km depending on terrain and interference) and up to 11 km at 2 W in good, open country. A UHF base transmitting in the 400 MHz band needs an ACMA apparatus licence.
The V10a is about 800 g on the pole, IP68 rated and rated to survive a 2 m pole drop. RTK accuracy is 8 mm + 1 ppm horizontal, and its IMU compensates for pole tilt up to 60°.
A tripod for the base and a survey pole for the rover: add our HDF94 heavy-duty tripod and the FJD carbon fibre pole below. The base screws onto any 5/8-inch survey thread; for setting up exactly over a survey mark, use a tribrach.
FJD Trion V10a GNSS receiver

A built-in 4G modem takes network corrections with your own SIM, and the 2 W UHF radio takes corrections from your own base.

About 800 g and 130 mm across. FJD says it's 18% smaller and 15% lighter than its previous model.

8 mm + 1 ppm horizontal accuracy, and the IMU handles pole tilt up to 60°.

FJD's rugged Android controller with a keypad and 4G, with Trion Survey ready to use.


The base sends RTK corrections to your rover over UHF radio, so you can work where there's no mobile signal and pay no correction subscription.

FJD rates the 2 W radio at about 5 km in normal conditions and up to 11 km in good, open country. Antenna height makes the biggest difference.

Up to 10 hours at 1 W from the internal battery, or run it from an external 9–32 V supply.

Good service and easy process
TThicks2 weeks agoGreat service and great laser. Got a 3-axis laser level and after dropping it from the second floor onto concrete one of the glass housings was damaged but the Redback team was super responsive and sorted a replacement part within a few days. Just good service and a good product.
TThomas Andersen2 weeks agoGood product for the price, amazing service, had a problem with my receiver, called and explained the problem, a new one arrived 3 days later in the mail, these guys are the best.....
AALLAN P.3 weeks agoGood quality, good price, I used it straight away with my Redback laser and everything works well.
AAdrian4 weeks agoTop service.
SSteven BAUER1 month agoEasy purchase fast delivery
KKoby Boer1 month agoJust what I needed - accurate, easy to use
TTrav Mcmahon3 months agoJack and the crew have been one of the best business to deal with. For three years I've had no issue with their products but when I had a fault they were brilliant to deal with on the phone and had me bask working within days, with was great considering I first call on a Friday afternoon.
RRob Thompson3 months agoThe help i got from Tim and the guys was second to none.....they returned my calls immediately and kept me in the loop looking for what I needed.....my purchase was expressed post so didn't hold me up with construction.....I wouldn't buy laser equipment from anyone else.....thanks guys
JJay Saunders7 months agoRedback lasers sent the product fast which saw me receive the product in no time. I also received a free upgrade to a lr730 which I was stoked about. The LR730 works a treat for getting heights set out precisely
