Utility lines and metal detecting

[Hot Rockin]

So new to detecting I'm still waiting for my detector to be delivered.

How does a metal detector respond to utility lines like electric, gas etc...
I am not trying to find them but rather avoid digging any up by mistake.
Are they deeper than I am likely to dig?

I ordered a Land Ranger Pro.

First off odds are any utility lines should be deep enough as to not be an issue when metal detecting or if not at least clearly marked.

I am able to identify old water lines, leading from a house to the street. Always a solid mid-tone, in a straight line.

In ground is way deeper than you will ever hit. Above ground power poles you need to know will interfere with reception.

Depends on where you are. I've noticed in a lot of sports fields and parks, the utilities may not be buried that deep. If your machine starts making a lot of noise only in certain areas then it's probably electricity. Non-electrified pipes/conduits don't send out EMF and act more like ordinary targets; they're just big - use your pinpointing function to draw them out on the ground and you'll see a straight line.

Power lines in general can be problematic - Minelab machines seem to handle them best. If you hear a cyclic hum or hear a bunch of noise there is probably a power line nearby - try raising your coil shoulder height and see if it goes away. If it doesn't it is probably above ground; if so, then below. You can try lowering the sensitivity if you want to try hunting in those areas - doesn't always work.

Cable lines will also make the machine chatter. There usually less then a foot deep. When in doubt, don't dig. I wrapped my lesche completely with electrical tape. Had a bad experience many years ago. Tip: Turn your sensitivity down if you have overhead lines. Not sure if it works underground, but I would steer clear of that anyway. HH

Just watch out for electrical lines at residences that might be buried shallow going to outside lights or landscaping, but if you do hit one it only tickles. Ha.
