I am also struggling to see the difference. BK117 might not be the most stable platform for offshore rescue, but the basics look right.
-Two qualified offshore experienced pilots (IFR and night experience is not mentioned in the articles?)
-Twin engined, offshore equipped machine.
Not sure what is better...
-Knowing that other/more southerly countries spend big bucks for modern/large SAR machines and then dont spend any money keeping their crews qualified and in good currency for the mission.
-Knowing that Germany is using older/smaller aircrafts for the same job, but then spends more money to keep the crews in frequent training for the daily job.
