Sorry for the waayyy slow reply -just got my laptop fixed.
It is in absolute new condition -cost nearly $200 w/ shipping costs.
now has a small squeeker eletronic caller that draws the animals eyesight away from you ,you can place it 50-100 yds away -use the fp-38 until you spot the animal then let them home-in on the squeeker call.
The only problem w/ remote eletronic calls is that they are only aimed one way -panning the sound around makes a big difference ,having the predator coming and looking straight at you is a recipe for disaster.
You can aim the sound and have much better volume control -then when the predator is within hearing of the squeeker call he'll go to it allowing you to moved the gun more easily.
This is a very simple -reliable caller w/ a great selection of sounds -the aggressive jackrabbit sound works great as do the coyote sounds.
I've used the crow sound while calling w/a handcall simultaneusly and called in two coyotes and killed them both.
