I've been looking on Foxpro's website comparing their callers, and it seems like these two are the ones I'd be interested in. I'm splitting the cost with my brother, so the Firestorm isn't cost prohibitive, but I'm wondering if the cost difference ($220) is worth it with regards to the features. It has two speakers, but it sounds like one is devoted specifically to low frequency sounds. The storage on the Firestorm is internal as opposed to a micro SD card, and the Firestorm has a 5 year warranty as opposed to a 1 year warranty. Other than that, they seem relatively similar. I guess my question is if there is anything about the Firestorm that would actually make a difference in the field. My share of the cost difference is only $110, so I don't mind ponying up the dough if it's worth it, but...is it? Does anyone have experience with any of Foxpro's more expensive calls that lead them to believe the extra cost is worth it compared to their less expensive models?
