so the remote will only handle 24 sounds and the unit can hold more. is there an sd card in the remote to.
Not sure what's inside the remote but there is nothing that is removable.
Its actually a decent call. If on the ground, the remote range is not very good (maybe 40 yards). If off the ground, hanging from a tree for example, I was able to get well over 100 yards (actually I'd say 150-175). I think all foxpro units get less range when on the ground. The spitfire has a tripod socket on the bottom so you can get it off the ground using a small tripod if out in a field.
The speaker/sound clarity is excellent even at top volume. Not sure how to describe the volume loudness. The volume goes from 1 - 5. Volumes 1 - 3 are not very loud at all but it takes a big jump from 3-4 and another big jump from 4-5. In the house, at top volume, its quite uncomfortable to listen to. Outside on a calm day, I can hear it echoing off the hills about a km away. If a windy day though, it doesn't sound very loud at all once I get approx 75 yards away from it. Hopefully the critters can hear better than I can.
The unit is not at all waterproof and I wouldn't use it even in a light mist. I have been using mine in a large ziplock bag (both unit and remote) and it doesn't seem to affect remote function/distance etc.
I had one of the version 1 models and I had trouble with both the mute button and it would sometimes play the wrong sound. I would suggest that if you are going to buy one, you ask what version it is (version shows up when you power on the remote). If the vendor is selling version 4 your good, if not, I'd pass or expect that you might have to send it to foxpro for an update.
