I have ELT although I think it should be listed second after Spot/Inreach. Even modern ELTs are known to not be very reliable in crashes. They often either don't get activated, break, or their antenna break. A spot/Inreach will at least provide approximate location. Also with spot/Inreach chances are that your crew/friends/club/FBO will be the first to notice an issue and can use better judgement than SAR who may just get an ELT signal.
