About the company
Echo81 LLC, a service-disabled veteran-owned small business (SDVOSB) and veteran-owned small business (VOSB) based in Hartwell, Georgia, supplies hydrographic survey equipment, sonar systems, marine positioning sensors, and specialized maintenance services to federal agencies as a prime contractor on 97% of its recent awards. The company operates primarily under total small business set-asides and SDVOSB designations, with SBA certifications expiring January 2028.
Echo81's capability footprint centers on underwater survey technologies and marine research equipment: multibeam echosounders (R2Sonic, EdgeTech), side-scan sonar systems, sub-bottom profilers, positioning and motion-compensation systems (Applanix POS MV variants), GNSS subscriptions, and associated hydrographic software (HYPACK, HySweep, SonarWiz). The company acts as an authorized dealer, installation center, and service provider for these systems. Representative prime work includes a $189.3 thousand purchase order from the Army Corps of Engineers for GNSS positioning service subscriptions supporting survey vessels at Panama City and Irvington through June 2029; a $143.1 thousand sole-source small-business-set-aside purchase order from USGS for an Otter uncrewed surface vessel for the Upper Midwest Environmental Sciences Center; a $135.9 thousand purchase order from the Navy's Bureau of Naval Personnel for an EdgeTech 6205S2 bathymetry sonar system installed at the Naval Academy; a $112.8 thousand small-business-set-aside purchase order from NOAA for side-scan sonar equipment to document shipwrecks at the Wisconsin Shipwreck Coast National Marine Sanctuary; and a $2.5 million blanket purchase agreement with the Army Corps of Engineers Engineering District Jacksonville for repair, calibration, and installation of R2Sonic and EdgeTech hydrographic survey equipment running through October 2028.
Customer concentration is extreme and heavily weighted to the Army Corps of Engineers. The top two customers — the Army Corps of Engineers Engineering District Jacksonville and the Army Corps of Engineers (broader) — account for 54 awards and $8.3 million in combined potential value, representing 63% of all awards and 82% of total dollars. The USGS, NOAA, and Navy together add six additional customers but represent only 14 awards and $811 thousand. The top five customers by potential value cover 93% of Echo81's combined potential value. This concentration reflects Echo81's role as a specialized supplier to a narrow set of government hydrographic and marine survey missions, not diversified across civilian IT or defense IT like peer small businesses.
Echo81 holds a single large blanket purchase agreement with the Army Corps of Engineers Engineering District Jacksonville (W912EP17A0012, $2.5 million through October 2028) that anchors 34 task orders carrying $711 thousand in combined potential value. Three additional BPAs with the Corps carry 11 task orders across $220 thousand. The vast majority of Echo81's work flows through these Corps BPAs or direct purchase orders; the company does not sit on government-wide acquisition contracts, GSA schedules, or multi-agency IDIQs.
Recent activity shows a sharp decline. Awards per year fell from a peak of 12 in 2024 to four in both 2025 and 2026, suggesting either market contraction in hydrographic survey equipment procurement or recompete losses. Only four awards face ultimate completion within the next twenty-four months (combined potential value $317 thousand), indicating limited near-term recompete exposure but also a thinning pipeline. Combined potential value across all 86 awards totals $10.1 million with $5.9 million obligated to date, a 59% obligation rate typical of equipment procurement.
Echo81 operates almost entirely as a prime contractor (97% of awards) with minimal subcontract footprint. Three recent sub awards under Atlantic Diving Supply, Inc. concern EdgeTech sonar systems (3400OTS light-pole mount, 4125I rack-mount side scan, 4205/2050 topside configurations), consistent with Echo81's role as a specialized equipment supplier rather than a systems integrator or service provider.
Echo81's NAICS footprint reflects its equipment-centric business model: 39 awards fall under Other Electronic and Precision Equipment Repair and Maintenance (NAICS 811212), 13 under Search, Detection, Navigation, Guidance, Aeronautical, and Nautical System and Instrument Manufacturing (NAICS 334511), and eight under Software Publishers. Primary PSC coding mirrors this — 43 awards carry maintenance and repair of electrical and electronic equipment components (PSC 5835), six involve underwater sound equipment procurement (PSC 5831), and seven concern software licensing and maintenance (PSC 7030/7045).
