Thank you very much Adam for making the review!
I will try to answer some comments below.
From the Retra website, where they ignore the GN units and get the Energy rating wrongTECH SPEC:
- GN30 in comparison with two strobes - see comparison here
- GN18 (absolute measurement on land)
And so on.
Thank you "tursiops" for noticing the mistake in the energy formula, it should of course be multiplied (*) and not divided (/).
In the comparison we stated that the GN calculation was done at 1 meter. We've amended that as well so it is now clear directly in the specs.
-battery indicator... though i like in principle the idea, in reality it didn’t turn too reliable, and after exchanges with Retra it appeared it was due to me using very old batteries (1st gen eneloop). I bought some new eneloop pros but couldn’t try them as i had to return the strobes before.
-batteries drain if left in strobe turned off! Again this may not happen with my fresh eneloop pros, but with my inons i had the habit to leave batteries in between dives (usually i dive once a week on weekend only) and that wasn’t a problem with inons
