I must confess moving from Inspo to Meg the thought of running manually was my area of concern .....

It was surprisingly easy and I now wouldn't do anything else - I usually hold setpoint at 1.3 with the unit firing at 1.2 as back up - works very well and the solenoid is a very good alarm if you are not use to it every couple of minutes - and of course it is very reliable if you have your hands full !

I have the option of using the Meg's electronics to maintain setpoint but do like the lekkies backing me up rather than the other way round. Complacency or distraction was my biggest concern on my Inspo at the potential wrong time, I can confess to not looking at those hand sets as often as I should have on occasions. Could've been fatal given the wrong circumstances?!

Having said that, on the Meg (APECS II) I do need to change that setpoint on the way down to back me up & it is always part of my buddy check before swimming away from the shot .... I wouldn't want to forget - just in case!!

Pros and cons to both I suppose?

Cheers.

I learned to dive the Meg as an mCCR, with the eCCR being the backup, and have also never found it troublesome. It is extremely easy to maintain a setpoint. I find that the first clue that I need to add O2 is a slight drop in bouyancy, along with a slight perceived drop in loop volume. By paying attention to body and bouyancy, as well as the PO2 readouts, I generally maintain a pretty tight setpoint running manually.
