Mapping services charge $299+ per property — you can do it yourself in an afternoon

“use small flags and pin them on visible sprinkler heads and then check the map to find the missing heads easily.” — real buyer, https://www.dripworks.com/blog/how-to-locate-the-sprinkler-heads-with-overgrown-vegetation

There are now services that will send a technician to GPS-map your property — every sprinkler head, valve box, and line — with packages that start around $299 for a single residential property (more for HOAs and commercial sites), delivered into a subscription dashboard. That is real value if you run a facility, but for a homeowner it is a technician visit plus an ongoing platform to hold data about your own yard.

The do-it-yourself version is the flag-and-map trick from the quote above, made permanent. Run each irrigation zone so the heads show themselves, then stand on each one and record its GPS point with a short relative note like 'Zone 2 head, 11 ft NE of the maple.' Phone GPS can drift several feet under trees, so re-average the reading and let the note bridge the last few feet. An afternoon of this covers every head, the shut-off valve, the well head, the septic lid, and your property corners — and unlike flags, the marks survive mowing, mulch, and winter.

Artifact Tracker Studio is the tool for that afternoon: one tap marks the spot, the Compass Tracker walks you back to any of them with a live distance countdown, zones outline each irrigation loop with area in sq ft and acres, and everything exports to GPX, KML, or CSV. It is a one-time purchase — a fraction of a single service visit — with no account, and every mark stays on your phone. Try the free live demo first.

Common questions

• How much does it cost to have a property GPS-mapped professionally?
  Published packages start around $299 for a single property (mid-2026), rising for HOAs and commercial campuses — typically delivered into a subscription platform. Doing it yourself with your phone costs a one-time app purchase and an afternoon.
• Is phone GPS accurate enough to map sprinkler heads myself?
  A single reading can drift 10–30 ft under trees, so re-average several readings and add a relative note like '11 ft NE of the maple.' Together they put you within a shovel-width — the same technique pros rely on notes and photos for.
• Do I have to pay monthly to keep my property map?
  Not with a buy-once tool. Artifact Tracker Studio stores every mark in your phone's local storage with no account or cloud — there is nothing to renew, and you can export GPX/KML/CSV backups anytime.
