Tracker Maxima 5000 For Sale (used) - Frequencies of 216 -220 and stores 30 sub-settings in memory. Comes in a black plastic case with manual, DVD user guide, unit holster and unit. The unit works perfectly and appears to have had very little actual use. No use marks of any kind on the unit itself. The holster appears to have been carried regularly. Former owner was probably a dog person and must have carried it 'just in case'. No dog collars or transmitters come with the unit. Price + whatever it cost me to ship it to you. This is the most convenient telemetry unit for falconers, hunting dogs, wildlife research and even law enforcement applications.
