  • Targeted at vessels from 10 to 300 ft, so it does not address the largest commercial tonnage
  • Pricing is not published and is arranged directly with the vendor
  • The SM300-NG is the class-approved unit, so the cheaper SM300-SP does not carry the same approval

Signal Ocean Platform

  • No pricing tiers or plans are published; specific costs require contacting the company or requesting a demo
