Why the MNS 4000?
Scanner Receivers:
A distinct advantage of the MNS 4000 over scanner type receivers is its sensitivity. Scanner type receivers are designed to receive radio broadcasts sent at significantly higher power than the FCC allows any tracking transmitter to utilize. This in turn means that scanner receivers are far less sensitive, many over 30db (roughly ten times) less sensitive!GPS Tracking:
GPS tracking systems are also at a disadvantage when compared to traditional radio location systems in the field. GPS systems guzzle batteries and you will be limited to a mere 24 hours of tracking time before having to replace batteries. This is bad news when a dog has gone missing. Despite this, the GPS systems also have far less range, maximum range of GPS systems is 5-7 miles (but typically much less) with line of sight whereas our traditional radio tracking systems can easily surpass 20 miles in range and last for months without battery replacement.
