Just Point and Measure
Aim the green laser at the mark and record it from where you stand. FJD rates laser points at 2.5 cm within 3 m with up to 30° of tilt.
1 / 7
Network corrections only. The V4e Pro gets its RTK corrections from an NTRIP service (a paid network, or Geoscience Australia's free AUSCORS) through the E600's 4G, so you need a SIM and mobile coverage on site. It can't be used with a base station.
This bundle includes
The FJD Trion V4e Pro + E600 Controller Kit with an FJD carbon fibre survey pole. Use the V4e Pro in your hand with its laser and tilt compensation, or screw it onto the pole for conventional pole work. The E600 Android controller comes with Trion Survey ready to go (no licence to buy) and has its own 4G for network corrections. It works with network (NTRIP) corrections only and can't be used with a base station.
Everything in the V4e Pro + E600 Controller Kit, plus an FJD carbon fibre survey pole. You supply the SIM and a correction login.
The built-in IMU handles tilt up to 60°, so you don’t hold the receiver plumb over the point. Aim the green laser at a peg, a post or a corner and record it from where you stand. FJD rates laser points at 2.5 cm within 3 m with up to 30° of tilt, and 3.5 cm at 60°. For stakeout, follow the beam to the design point and the app confirms when you’re on it.
The bright Class 2M green laser stays visible in sunlight and ranges from 3 cm out to 60 m. For conventional pole work, screw the V4e Pro onto a survey pole with the supplied adapter.
The E600 is FJD’s 5.5-inch Android field controller, with a physical keypad, 4G with two SIM slots and an IP67 body. Trion Survey comes ready to use on it, so unlike running the V4e Pro from your own phone, there’s no licence to buy.
The E600 connects to an NTRIP correction service over 4G and passes the corrections to the receiver over Bluetooth. You supply the SIM and the NTRIP login: a paid network subscription, or Geoscience Australia’s free AUSCORS streams. You’ll need mobile coverage on site. The V4e Pro doesn’t work off a base station. Keep the E600 within about 5 m of the receiver.
At 320 g and 182 mm long, it fits in a jacket pocket. It’s rated IP67, survives 1.2 m drops and runs about 12 hours on a charge (less if the laser and tilt are on all day), then recharges in 3 hours or less over USB-C.

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.....

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
