I have about 50 dives since being certified 2 years ago and the addiction has hit me hard. I travel solo on most of my trips and dive with reputable companys. They always pair me with a DM or a dive buddy but I am always concerned my dive buddy might not be reliable in case of a malfunction...Is the Spare Air/ or pony bottle a good option for me??
It is the easiest solution. The best solution would be to become a good diver and find good buddy's for dive trips.
For a solo diver it would be a good solution. But if you are not a solo diver and have good buddy's than there is no reason to use a spare air/pony bottle.
