Some comparisons of AEM systems for specific mineral exploration problems

Simple comparisons of airborne EM systems are limited, and those that are available have finite relevance of ~ 5 -10 years due to ongoing improvements in current systems and new systems being offered. The comparisons are hindered by the myriad of system design features, but moreover each comparison must have a purpose, as no system is 'the best', but there are many systems 'suitable' to answer exploration questions. Several comparisons are presented here, where systems are compared for a specific application using mostly coincidentally acquired field data.
