How I Found Hidden 1950s Boundary Marks Using New Survey Tech 🧭⭐

These 1950s survey marks are almost completely lost… but can I still find them in the middle of suburban Sydney?

In this fast-paced, 8-minute episode, I head to St Ives, Northern Sydney to search for survey marks placed over 70 years ago — many now buried under gardens, roads, and driveways. Using cutting-edge Leica technology — including the Leica GS18 GPS Rover and AP20 SmartPole — I try to bring these hidden marks back to life.

Join me as I blend historic land surveying methods with modern GPS precision to uncover what time and development have tried to erase. It’s a real-world mix of fieldwork, history, detective work, and surveying gear — perfect for anyone into surveying, Leica gear, or old benchmarks.

📍 Location: St Ives, Sydney, NSW
🛰️ Equipment: Leica GS18, Leica AP20 AutoPole, iPhone XR, Insta360 X3

I don’t make this content for self-gratification or attention — I do it because I genuinely believe surveying is an incredible and often overlooked field. My goal is to share knowledge, spark curiosity, and help people better understand what we do as surveyors. If I can make a living from this along the way, that’s fantastic. But if I can inspire more people, help students, or even just make someone’s day a bit more interesting by showing them something new — that means even more.

If any of that inspires you, feel free to like, share, subscribe, or even donate — it all helps me keep doing what I love while helping others along the way. Thanks for being part of the journey.
