I am curious how many Garrett AT PRO metal detectors have been made. I have no idea what sort of numbers metal detectors are built in general. All i do know is that I have seen mention of serial numbers that start with 504, 505, and 511. I wonder if the three digit number changes represent modifications or are just consecutive numbers. Are metal detectors made in batches of 100's or 1000's? I really do not have any idea of how many people in the USA or world wide are involved in metal detecting. Does anyone know or have an estimate of the number of AT PROs that have been built, or the number of people who MD?
Thanks,
