well i could not hold out any longer. so i pulled the trigger on the new scorpion 1xb. i thought it would work great due to its portability. just not sure how loud it is. im going to pick up a sp-55 just in case i need it. i was going to use it for bobcats,bear and yotes. most people i see said they really did not need the extra speaker. thought about getting the firestorm. but this unit seemed to be easier to do with a walk in hunt. were some times you have to cover alot of ground. just not sure what sounds to put on it. have some ideas. this is my first electronic call. boy im excited to try this thing.let me know what sounds to put on it. sure could use some help. thanks
