(i) unbalances
(ii) cant check it for leaks/turn it on/off
(iii) people breathe from wrong reg and end up dead
(iv) heavy on back on land
(v) cant be handed off to someone else or a boat to get back onboard
(vi) 2 more hoses coming in front of you so chance of checking wrong gauge and/or breathing wrong reg exists..and it does happen.
I cant see a single advantage to back mounting.
Are you for real?
(i) shift the weight you carrying to one side to balance out.
(ii) mount it upside down. easily reach the valve. as for leaks - my hoseless dive computer monitors the gas pressure.
(iii) those folks should not be diving at all. perhap they should give up scuba all together.
(iv) your point is? rather be on your back or sling. weight the same.
(v) won't argue with you here. but my pony is for me. not someone else. everyone should have their own bail out bottle.
(vi) only hose from the pony coming up to the front is the reg itself. no mistake in breathing the wrong regulator. as for gas pressure hose. it is hoseless.
biggest advantage. both your hand and arm are 100% free. base on your answers - obviously you do not hunt underwater. hence you do not know the difference?
