Dear Sir/Madam, This is RAHEEMLawal from US. I'm looking for smartwatch GPS and LBS and APGS with the following specifications: Can your watch be modified to have the capability to switch mode from GPS navigation mode for (above ground) detection to SAR- Synthetic aperture radar or ground penetration radar (GRP) detection mode and used to ping or detect bodies under a debris or basement at least (10 ft or 3.5 meters) during a disaster search and rescue operation - I will like to use the watch to detect people that are not dead first. Also, the watch is able to switch the mode to acoustic mode in water with detection capability up to 100 meter in water. What is the lifetime of the current batteries? We might need to modify the watch to include another auxiliary battery that can be activated only during the search and rescue. The watch will be called Ultimate D Rescue and Ultimate D Finder Show More
