It seems that all the fits I have seen for Exploration frigates use either a MWD or AB.
I have 2 different ships I Explore with. A Magnate and an Executioner. Both have only three mid slots. I find the most useful fit is Relic Analyzer, Data Analyzer, Cargo Scanner. Early on I would drop one of the three for a MWD. However, I came up with the idea of dropping a bookmark on grid as I am warping to the site. I bounce the bookmark between cans. After that, I found I didn’t use the MWD at all so I dropped it.
I had seen a youtube of a player who said she fitted the MWD to travel quickly between sites. I find on average the amount of travel time is about the same (quicker for farther cans, slower for close ones). Having both analyzers and the scanner more than make up for any possible travel deficiency.
I’m sure I’m not the first person to come up with this idea. Is there some other reason that I am missing that I need a prop mod for Exploration? Thanks
