Safety scope

ScanMark DC turns your scanner readings into a drill decision as a field aid. It is not a scanner, radar, structural approval, or anchor-capacity approval; it does not measure what is inside concrete and is not a substitute for a qualified scanning operator or the structural engineer. The edge-distance check is geometric clearance only and does not approve anchor capacity. Treat post-tension decks as live until proven clear, treat a lone shallow reflector as possible energized conduit, and get engineer approval before cutting structural steel. Verify every reading and decision before you drill.

FAQ

How deep can I drill into a slab without hitting rebar?

Use your scanner cover reading, subtract the instrument tolerance and a safety margin, then verify the result before drilling.

How do I tell a post-tension cable from rebar?

Rebar usually reads as an orthogonal grid. A tendon candidate is deeper, single-direction, draped, and off the bar grid. ScanMark DC stops on that signature.

Does it work without internet?

The field flow works offline. Purchase, restore, and entitlement checks use RevenueCat-backed Google Play, and whatever app you share to may need network.
