The 280NCP Platinum Dogtra Training Collar is in the NEW line of electronic shock collars offered by Dogtra.

This collar has some bells and whistle upgrades over the other base collars.

At a Glance:
 LCD screen to view the stimulation level transmitter is set as well as battery life remaining
 1/2 mile range
 Works with mild mannered dogs but is powerful enough to use on a stubborn dog
 Waterproof collar and transmitter
 Nick and Constant buttons for stimulation levels.  The Nick button is half the power of the constant button and only gives a brief pulse of static shock even if the button is depressed for a long period of time.  The constant button will continue to emit statis shock for a period of 20 seconds and then will cease until the button is released and depressed again.
 No external antenna on collar
 Vibtration/pager only button which is a great use expeically in mild mannered dogs

This dogtra training collar is a step above the 200ncp in that it provides the LCD screen and 127 levels of stimulation to choose from.

This is a great entry level collar for hunters and the LCD screen is great in low light situations.
