We are selling our last remaining survey systems: Teledyne Optech LiDAR (700m scanner), GeoSlam ZEB scanner, Topcon Hiper V, Topcon FC-5000, survey legs, high range radio antenna. https://www.hcsurvey.com.au/resources/

Make an offer, all as is, freight additional. Great for a surveying start-up where you need the kit but can't afford to buy brand new. Laser scanners are hardly used, sitting boxed and waiting for field work. Contact us now.

We can send internationally but you will need to arrange all freight and clearances.

Combine laser scanned shore side infrastructure with your multibeam soundings to achieve excellence in modelling and engineering design.

Save the date, then take the journey...

We invite you to join the Australian Hydrographic Office and SSSI for a HydroScheme Industry Partnership Program (HIPP) Seminar taking place on World Hydrography Day.  The day was adopted by the International Hydrographic Organization as an annual celebration to publicise the work of hydrograp...

Due to the ongoing NSW floods, have been busy contributing to the clean-up within the Hawkesbury river since 2021. Depending on river depth, have been using a combination of Side Scan Sonar, Single Beam and Multibeam Echosounder to identify natural and artificial debris for removal, and locations where navigational has been compromised. Working with the NSW Environmental Protection Authority (EPA) as lead and Transport for NSW Maritime.

For more information about the project, following the NSW EPA link:

We have several clean-up programs to help with the collection and disposal of debris from the March 2021, February-March 2022 and June-July 2022 storms and floods.

When you have no boat ramp, and a USV doesn't have the right gear, then you need to use another launch strategy. Lino and Lena found a crane to be the best solution and successfully mobilised HCSurvey's 4.6m vessel for a multibeam survey at a remote dam in the vicinity of Appin, NSW.

Sometimes, the things you see at a boat ramp from the less experienced can be scary...

So there we were, ERROR E/S NOT PRESENT. Why? Well we knew why. The transducer cable had taken a lot of movement at the stem of the thread over the years as it is a portable system. On and off, treat with care... At some point it has to break internally.

Well, we asked the manufacturer if they could re-terminate it and they said 'Nahhhh'. We asked a reseller that makes echosounders if they could re-terminate it and they said 'Sorry, broken too close to the thread, irreparable'. We asked a rental group with technicians skilled in this sort of stuff and they said 'We have a plan, it'll cost you!'. Well, not in those words but you get the point.
So I said, 'Team, it's no good like this. Let's cut 30mm from the stainless thread and re-terminate it ourselves'. Now Lino is a keen repairer and loves to cut things so I gave him the pliers...

Ok, so I removed the outer mesh without contemplating that it formed the Earth for the circuit. Yes, forgot to go to the schematic. We fixed that problem as well by using a segment from the offcut.

Next, Lena (our Intern from France) and I started the re-termination...

We used some natural fibre rope to insulate between the wires as this was similar to that in the cable to start.

We exposed the wire mesh at the cut ends, wrapped the offcut wire mesh around to join the ends and make the Earth. Tested the continuity and finished off with amalgam tape.

Next comes the syringe... A perfect cylinder in which to pour the 2 part epoxy flex resin, 15min work time, 12 hour set time.

And finally, yes, it works. Pinging like a champ and a repair bill of A$20 in parts, maybe an hour in labour.

So next time you have kit that is broken, out of warranty and you want to train your staff in the technical side of equipment, set yourself free and fix it yourself.

Versatile, works in GNSS denied areas, on our boat, car, handheld, backpack, small spaces, large spaces... We just went GeoSLAM.

ZEB Horizon, we'll be taking it for a run, walk, sail soon.

We're on the move, hopefully for the last time.

Our new address is Unit 27, 7 Waynote Place, Unanderra, NSW 2526.

Is this where the gold is? Shipping, how you have your standard of living delivered. Hydrographic surveying, how shipping gets your wants to your port. Pictures not artificial, take the message how you choose.
