I have up for sale a GREAT invention for us two way radio and scanner heads - its called the POWER TAMER! 

This is a small 12 volt module that wires in line to your two way radio, scanner, or other vehicle equipment power - anything with 12 volts it can control!  Using dipswitches you can select a time between 15 minutes and 16 hours - and when that time elapses from turning the vehicle off, it will shut down all power to your equipment!

No more having to turn all of your scanners on and off each time, set the volumes, get adjustments right, etc - simply turn off your vehicle and walk away.  Upon turning the vehicle back on the module senses the voltage rise and automatically powers all equipment back up - without you touching a thing!

There are also other cool features built in such as an auto shut off if the vehicle voltage gets below 10.5 volts, saving your battery. 

New, these units sell for $89.95 tax and shipping.  I have a few of these and am selling them first come first serve for $25 each, USPS shipping and paypal fees included!  Simply paypal $25 and I will get your Power Tamer fired off same day.  Includes 2 page wiring directions and info sheet. Thanks!
