Space age parts!

Holy mark-up!
I built a LiDAR level detector for my water tank. About $7 for an Arduino and $11 for the LiDAR. Bought in bulk it would be a heck of a lot less.
Glad to see someone beat me to an idea I had though … again.

When I worked at Ole Miss, the acoustic research group I was part of developed an acoustic based landmine detection system. I did the mech engineering/design. LIDAR mark up is nothing compared to DoD mark up.

We used LiDar and GPR for finding IED’s and landmines in Iraq and Afghan. Retired USMC EOD.

Thank you for your service.

GPR was the technology that we were "competing" with for landmine detection. GPR is faster than acoustic, but also produces a lot of false positives. The DoD was planning on going with a hybrid system that would interrogate a large area quickly with GPR and flag suspect spots, then go back in with the acoustic system to scan those hot spots. Not sure whatever happened with the landmine detection, after I left and moved back to CO I didn't keep up with it. That was probably the coolest job I had.

The last couple of years I was at Ole Miss, funding was being shifted from landmines to IED detection. Acoustic detection wasn't really applicable for those targets, especially when they were covered in a pile of rocks.

Those systems are good for deliberate ops in a non-kinetic environment. We used GPR heavily im Quantico Va while mapping out an old impact area.
