Welcome to Georgetown Instrument Services
GIS is no longer an FAA certificated repair station. Please contact Castleberry Instruments & Avionics for your instrument and avionics needs!
Competitive prices, high-quality workmanship, quick turnaround time and service. GIS personnel have the ability to meet that challenge to exceed customers’ expectations every day. That’s why customers depend upon GIS full services, from testing, overhaul, and repairs to exchanges and outright sales. Try us, you’ll be glad you did!
