One of the newest Dogtra line of electronic training collars, The 7000M also referred to as the Surestim features a new implementation in the transmitter which is held by the trainer.  The transmitter will vibrate once the stimulation button is pressed giving the trainer positive feedback that stimulation was sent.  When you are hunting or outside many times you are wearing rather large gloves and are not aware if you have depressed the button all the way.  This way you know by the response vibration in the transmitter.

It still has all the features of the Dogtra great line of electronic dog training collars.  

• Rechargeable batteries
• LCD readout screen for view of stimulation set and battery life
• Totally waterproof
• 1/2 mile range from transmitter to collar
• three buttons for nick, constant and vibration only mode

This collar was designed to have a smaller receiver so it could be worn by the smaller dogs.  The recommendation is for dogs over 15 lbs.
