Haven't flown with my detector since 9-11 and decided to take it on this trip next week. I have a hard case modified for the Explore XS and it fits the detector, stock loop, upper and lower shaft,plus 2 batteries and charger plus car charger and also 2 battery operated probes by Whites. I haven't called the Airport but am concerned about the charger and batteries. Has anyone had a problem or am I being overly concerned and should I pack the extras in baggage ????
