NcWhitetail,

Took the Scorpion out on a couple stands today. Just working dogs and taking pictures. Anyway, got a better sense of the volume under real conditions. It's not as loud as the big speaker on the FX3/FX5, but the same as if you used the mylar speaker. It's certainly loud enough.

After playing with it more my take is that if I had an FX3 I'd spend the $200 for the upgrade to get the FX5. Same call, but the remote has nice features and I think it's worth it. If I didn't already have one I'd get the Scorpion as it's less than the FX5 and is really same call minus the horn speaker. It's hard to quantify volume with words, but if you tend to run whatever call you're using now at full volume and wish it had more, then you'll likely think the Scorpion isn't loud enough and would prefer the FX5.

The call is definitely good, but the remote makes it great. Which would make me look over the FX3.
