System & Hardware Requirements

Supported devices: MD Field Mapper Pro requires an iPhone Pro model with LiDAR. That means iPhone 12 Pro / 12 Pro Max, 13 Pro / 13 Pro Max, 14 Pro / 14 Pro Max, and 15 Pro / 15 Pro Max. Non-Pro iPhones are not supported.

iPhone Pro + Connector matrix

ConnectorSupported Pro ModelsAdapter Needed
LightningiPhone 12 Pro / 12 Pro Max, 13 Pro / 13 Pro Max, 14 Pro / 14 Pro MaxMOVO IMA-1 (Lightning TRRS interface)
USB-CiPhone 15 Pro / 15 Pro Max (and newer Pro)MOVO UCMA-2-IP (USB-C TRRS interface)

Why Pro only? The app’s mapping relies on on-device LiDAR for surface geometry and alignment. Only iPhone Pro models include LiDAR.

Required parts

🎚️

MOVO MV-RC300 (attenuating inline adapter)

Tames hot detector outputs and improves mic-level matching.

MOVO IMA-1 (Lightning TRRS mic interface)

For Lightning-based Pro phones (12/13/14 Pro lines).

🔌

MOVO UCMA-2-IP (USB-C TRRS mic interface)

For USB-C-based Pro phones (15 Pro line and newer).

🎧

TRS ↔ TRRS patch cable

Connects your detector’s headphone/line out (TRS) to the phone interface (TRRS, CTIA).

Cable lengths are personal preference. Shorter runs reduce snagging.

Wiring recipes (Pro models only)

Lightning Pro (12/13/14 Pro)

  1. Detector headphone out (TRS) → MV-RC300 attenuator
  2. TRS↔TRRS cable (CTIA standard)
  3. IMA-1 Lightning interface → iPhone Pro

USB-C Pro (15 Pro and newer)

  1. Detector headphone out (TRS) → MV-RC300 attenuator
  2. TRS↔TRRS cable (CTIA standard)
  3. UCMA-2-IP USB-C interface → iPhone Pro
Detector settings & cable order: start with low volume. The correct chain is Detector → MV-RC300 → TRS↔TRRS → Phone interface → iPhone Pro. Avoid wireless paths; if available, disable AGC/limiters on the detector.
