I have the Spitfire with the Jack Attack decoy,unless you are hunting wide open areas(i mean WIDE Open) the sound the Spitfire puts out is fine..Vol 1 thru 3 really isnt loud but when ya hit 4 its jumps up alot,Yotes as you know have great hearing so for the most part you dont need to Blast the sound.....
For the cost a person can't go wrong,I bought mine in a store so it was preloaded with sounds...Iam going to order another chip with the sounds I want,it will give me a total of 48 calls witch is more then I need but will be nice to have and it's still cheeper then thier nxt FoxPro....
