Weight and the cost of replacement battery packs are the two big ones. Beyond that I really don't have an issue with my SE, which is why I still have it.Off topic, but besides weight, what turns you off about the Explorer series, my 2010 model se pro is still my lone detector. I'm obviously not well versed in a variety of detectors, but I "think" it still can hold its own with the best?
I don't know exactly what it is about the 705 that entices me to stick with it, but it seems to speak to me, and it has a much more extensive language than a lot of other machines and I've grown accustomed to it.
