Pros & Cons

C
Carlson Scan

Pros

  • Shows the point cloud and mesh live during a scan, so crews can check coverage before they leave the site.
  • Calculates closed surfaces and volumes on the spot, which suits stope and void reconciliation.
  • Processes data on the device, so it works underground with no internet connection.
  • The license allows installation on any number of tablets, and version updates have been free for hardware owners.
  • Exports to E57, LAS, PTS and DXF for use in CAD and blast design tools.

Cons

  • Works only with Carlson's own scanners and probes, so it cannot be bought or used on its own.
  • Older C-ALS Mk3 and original Void Scanner units cannot move past legacy version 1.3.6.
  • There is no public pricing, and the hardware must be quoted through sales or dealers.
  • Almost no independent user reviews were found, which makes it hard to compare against rivals.
  • Runs on Windows only.

Propeller

Pros

  • Combines drone, LiDAR, GNSS rover and total station data on a single map, regardless of which hardware captured it.
  • AeroPoints give survey-grade ground control without the manual surveying normally needed to set control points.
  • Strong stockpile, cut and fill, and progress tooling, with a long track record in earthworks and aggregates.
  • Integrates with common construction systems such as Procore, Trimble Connect, Autodesk Build and HCSS.
  • The trust center shows a SOC 2 Type 2 attestation.

Cons

  • No published software pricing, so buyers have to request a quote.
  • Hardware such as AeroPoints and DirtMate adds separate costs on top of the software.
  • Reviewers find less depth for vertical construction and interior fitout work.
  • Some reviewers say the price may seem high to smaller clients.
