I'm not sure which Icotec I have (it's at the hunting cabin) but there are 200 sounds on it and the remote does not need to be line of sight like many. I like it. It hangs off of fence wires to get it up off the ground. I made an abbreviated list of the calls I would use and laminated them. There are about 10 different pup distress calls that I have used to coax in hesitant dogs. I'm sure there are louder callers but I'm not calling the prairie. I think it is the most bang for the buck. I have a separate decoy. The lighted remote is easy to scroll and figure out.
