About Echo81 LLC
Echo81 LLC, a service-disabled veteran-owned small business (SDVOSB) based in Hartwell, Georgia, supplies hydrographic survey equipment, sonar systems, positioning technology, and related maintenance and calibration services to federal agencies as a prime contractor on 96% of its awards. The company holds SBA certifications for both veteran-owned small business (VOSB) and SDVOSB status, expiring January 2028, and operates as a limited liability corporation.
Echo81's capability portfolio centers on the supply and field service of specialized underwater survey equipment — multibeam echosounders (R2Sonic and EdgeTech systems), side scan sonar, inertial navigation units (Applanix POS MV systems), GNSS positioning subscriptions, and associated firmware and software maintenance. Representative work includes a $189,335.91 firm-fixed-price purchase order from the Army Corps of Engineers for GNSS positioning service subscriptions supporting survey vessels at Panama City and Irvington sites through June 2029; a $143,072 purchase order from USGS Upper Midwest Environmental Sciences Center for a modular, fully electric Otter uncrewed surface vessel (USV) for integration with existing hydroacoustic sensors; a $135,997 sole-source Navy purchase order for an EdgeTech 6205S2 rack-mount bathymetry sonar system for the U.S. Naval Academy's Department of Ocean and Atmospheric Sciences; a $112,810 NOAA order for side scan sonar equipment to monitor the Wisconsin Shipwreck Coast National Marine Sanctuary; and a $74,581.88 Army Corps of Engineers contract for POSPAC MMS software maintenance running through September 2026. Echo81 also delivers software products (HYPACK, HYSWEEP, SonarWiz) and performs field repair, calibration, and installation work on deployed survey vessels.
Customer concentration is extreme and narrowly focused on Army Corps of Engineers accounts. The Army Corps of Engineers Engineering District Jacksonville anchors 28 awards ($4.7 million combined potential value), and the Army Corps of Engineers broadly accounts for 54 awards totaling $8.3 million — representing 64% of all awards and 83% of combined potential value across the portfolio. USGS, Navy, and NOAA round out the top five, collectively accounting for 15 awards and $708 thousand, bringing top-five concentration to 93% of dollars. This concentration reflects Echo81's specialization in hydrographic survey technologies for federal water-resource, coastal-mapping, and marine-science missions.
Echo81 holds two primary blanket purchase agreements. The single-award BPA W912EP17A0012 from Army Corps of Engineers Engineering District Jacksonville, valued at $2.5 million through October 2028, anchors the portfolio with 34 task orders ($711 thousand combined potential value) for repair, calibration, and installation of R2Sonic and EdgeTech hydrographic survey equipment, including multibeam echosounders, side scan sonar, inertial navigation systems, and associated services. A second BPA, W912EP24A0001, carries 5 task orders totaling $70 thousand for similar services. Two additional BPAs (W912EP17A0002 and Special Operations Equipment — Tailored Logistics Support) provide secondary vehicles with three task orders each.
Activity trended upward through 2024 (twelve awards) but has decelerated sharply — only four awards in 2025 and two in 2026 year-to-date. Across the full portfolio, 84 awards (81 prime, 3 sub) carry $10 million combined potential value, with $5.8 million obligated (58% realization). Only three awards reach ultimate completion within the next twenty-four months (combined potential value $289 thousand), representing minimal near-term recompete exposure.
Echo81 subcontracts selectively to Atlantic Diving Supply, Inc. on three recent sub-awards involving EdgeTech sonar systems (3400OTS light pole mount, 4125I rack-mount side scan, and 4205/2050 Starmux IV topside unit configurations) delivered between October and November 2024. The vendor competes predominantly under small business set-asides — 66% of named awards carry total small business designations, with SDVOSB and VOSB designations appearing across the prime footprint. NAICS coding reflects the equipment service and supply mix: 39 awards under NAICS 811219 (Other Electronic and Precision Equipment Repair and Maintenance), 13 under 334511 (Search, Detection, Navigation, Guidance systems manufacturing), and 8 under software publishers, with PSC concentration in equipment maintenance/repair (43 awards) and underwater sound equipment (5 awards).
