Forget your diving rods, joss sticks and general poking around when prospecting for new cave. This is what you need -

Being an armchair caver I tried to buy one but could not find any for sale

Alternatively, for an armchair, try Homebase or Ikea...

More seriously, how deep can this technology "see," and how big would the void have to be?

Keele Uni. Has a page on detecting passages associated with "blue holes" under a new port site. https://www.keele.ac.uk/geophysics/microgravity/casestudies/freeport/. Unfortunately the plot images are very small.

A scientific breakthrough in a Ministry of Defence research project could pave the way for a scanners that one day could see underground or through walls.

There's probably some tech out there that already claims that one day, it could lead to the possibility of there may be a small chance of something that might provide  the key to unlocking time travel.

I wouldn't get your hopes up.

Using gravity to make geological surveys is nothing new; this is just aiming to be a little more sensitive one of my favourite facts is that if you do careful scanning of sea level height from satellites, you can see the mid-ocean ridges where the sea level is higher because there is less gravity there (or something like that)...

Will the density of cavers affect the results?
