It only has a 20' range but for $20 several could be purchased and placed out of reach. Apparently not loud enough to bother neighbors but at least maybe a deterrent!
After following this thread (and as a minor hijack) I decided to check on Nebraska laws and we seem to have it pretty good here: Signs DO NOT need to be posted, but encouraged. Nebraska law states that any person entering property for hunting/fishing/trapping without the express permission of the landowner/renter, is either trespassing or hunting without permission. "Although “No Hunting” and “No Trespassing” signs help to discourage people from illegally entering private land, they are in no way required to keep people from hunting someone’s personal property"
Special signs that state “Hunting by written permission only” can be posted on a landowner’s property. These signs allow law enforcement officers to contact hunters in the field and require them to produce written permission, by the owner, stating they are allowed to hunt the area. Failure to produce a document granting permission enables the law enforcement officer to issue a citation without the landowner being present.
A landowner can take down a vehicle license plate number and write down a description of the individuals involved. This information, along with a signed affidavit by the landowner stating that the parties in question did not have permission to hunt, is often times enough for law enforcement (Game & Parks or sheriff) to cite a person for trespassing. The landowner is also not required to be present in court.
And lastly as I'm a renter:
Nebraska law says that unless formally stated that the owner retains hunting privileges when the rental agreement is established, the operator has the hunting rights and ability to grant permission to hunters on land they rent.
Just some additional info from another state and for fellow Nebraskan's!
One final note although signs don't seem to stay up too long, place a sign that states: IF YOU CAN READ THIS YOU HAVE BEEN CAPTURED ON CAMERA. IF YOU TURN AROUND NOW AND LEAVE THE SAME WAY YOU CAME IN, THE PHOTOS & VIDEO WILL BE TIME-STAMPED THAT YOU LEFT AND I WILL NOT PRESS CHARGES
