What to Look for in a Pipeline Locator
(A Guide for Kiwi Tradies)
Whether you’re chasing stormwater under a slab or trying to avoid costly guesswork on a sewer dig-up, a pipeline locator isn’t just another gadget, it’s your eyes underground.
With so many models and features out there, it pays to know what actually matters on real job sites. Here’s what Kiwi plumbers, drainlayers, and civil crews should look for in a locator that delivers in the field, not just on paper.
1. Accuracy You Can Trust
If it’s not accurate, it’s not much use.
Look for a locator that:
- Can reliably pick up the signal from your drain camera sonde
- Provides both depth estimates and directional guidance
- Handles NZ ground conditions, from sandy coastal soil to heavy clay and rocky sections
The goal is confidence before you start digging, not “close enough”.
2. Frequency Compatibility
Most drain camera sondes run on common frequencies like 512Hz (and sometimes others depending on the setup). Your locator must match the frequency your gear is using, otherwise you’re basically guessing.
Check that your locator is compatible with:
- The frequency of your camera head transmitter
- Any external sondes or jetter transmitters you use
Don’t rely on “works with most systems.” Make sure it works with your system.
3. Built for Real Job Sites
These tools don’t live in clean vans. They get dragged through mud, dropped on driveways, and used in the rain.
Your locator should be:
- Water-resistant or properly IP-rated
- Tough enough to handle knocks and grit
- Designed for rough, wet conditions common on NZ sites
If you have to baby it, it won’t last long in this line of work.
4. Battery Life That Gets You Through the Day
Nothing slows a job down like flat batteries halfway through a locate.
Look for:
- All-day runtime under normal use
- A clear battery level indicator
- Easy charging or quick-swap battery options
Not every site has easy access to power, so reliability matters.
5. Simple to Use, Even When You’re Wrecked
After hours in a trench or crawlspace, no one wants to scroll through complicated menus.
A good locator should offer:
- Straightforward buttons and controls
- Clear audio and visual feedback
- Quick-start guidance so you’re not stuck reading a manual on site
It should make the job easier, not add another layer of frustration.

Final Thoughts: A Good Locator Pays for Itself
The right locator doesn’t just find pipes, it helps you:
- Avoid unnecessary digging
- Finish jobs faster
- Present a more professional service to clients
In many cases, it earns its keep in just a handful of jobs by reducing time and rework.
