Concentration Risk Disclosure [Text Block] | 18. Concentrations Credit Risk— As of January 31, 2025, we had two customers that individually exceeded 10% of consolidated accounts receivable. As of January 31, 2024, we had four customers that individually exceeded 10% of consolidated accounts receivable. Revenue Risk— In fiscal 2025 and 2024, our single largest customer accounted for approximately 36% and 21%, respectively, of our consolidated revenues, with these revenues being generated from the Seamap Marine Products segment. Together, our five largest customers accounted for approximately 73% and 67% of our consolidated revenues in fiscal 2025 and fiscal 2024, respectively. Cash Risk—The Company maintains deposits and certificates of deposit with banks which may exceed the Federal Deposit Insurance Corporation (“FDIC”) insured limit and money market accounts which are not FDIC insured. In addition, deposits aggregating approximately $4.8 million and $4.9 million at January 31, 2025 and January 31, 2024, respectively, are held in foreign banks. Management believes the risk of loss in connection with these accounts is minimal. Supplier Concentration—The Company has satisfactory relationships with its suppliers. However, should those relationships deteriorate, the Company may have difficulty in obtaining new technology requested by its customers and maintaining the existing equipment in accordance with manufacturers’ specifications.
