Well, I have several MaraTracs and I know of a fleet of 250+ units that is the largest of the fleets I've serviced, they've been in service more than 15 years, and out of that fleet only 30 of the radios have had any serious repairs. Of those 30, way less than half actually had a major component failure. The rest were operator induced (Pepsi and latte inundations, abuse, or numbnuts fist hammering on the control head trying to make the back lighting come on, etc. Yep, he didn't know he could push that little button in the upper right portion of the control head). That doesn't include numerous things like mic cords, antennas, cables, vehicle water leaks, vehicle accidents. etc. MaraTracs are probably one of MotherMoto's most durable radio designs.
The cons are numeric displays (advanced control head) instead of alphanumeric displays, so you'll need to carry an excel spread sheet (just kidding) if there are more than X number of channels. The number X will vary inversely with your age.
Did I mention the lack of an alphanumeric display?
