Personal ELT is a choice. I usually carry extra things in case I go down somewhere remote. Handheld Transiever is best and about the same size as something other than Breitling (and less expensive) Consider though that very few folks monitor 121.5 or 243.0. So its nicer to have something on the frequencies used in your area.
Also an impact ELT usually means I dont need to be rescued anyway in most cases.
