More Details

The ergonomic handset sits firmly in the hand thanks to the no-slip rubber coating, and the controls are very easy to operate without looking down. The correction dial starts with a very low level suitable for the most sensitive dog, and increases gradually to the range needed for very headstrong, or strongly muscled, large dogs. DT Systems favours the Vibration training feature over Tone as they believe dogs respond more quickly to physical stimuli over audible tone. Many of our farmers find that their dogs respond so well to Vibration that they seldom need to use the static correction. Vibration is also great to get the attention a deaf dog. If you should manage to drop the handset riding through a creek, it is waterproof and floats, so no harm done if you catch it quick!

The H2O Plus Series lets you operate up to 3 collars off the same handset, just flick the Selector Switch to the black, green or orange dot that matches the collar. This allows each dog to be trained with the choice of ‘Vibration’, ‘Nick’ or ‘Continuous’, unlike some remote trainers which allocate each dog to a button and limit choice to stimulation only. If you decide to add another collar to your system just give us a call to order one, and when it arrives follow the simple instructions to code it in to your handset.

The H2O Plus has tough collars that stand up well to hard wear. We’ve even had some hit by pigs that were gouged but not broken and probably saved the dog’s life. You’ll get 3-5 days battery life on avereage and you can top them up if you get caught short with a 12v charger (regular charges should always be done on 240v). DT’s patented Maxx- Range 360 Antenna runs the length of the collar strap and enables more consistent contact between the handset and collar, even in rough or hilly terrain. Dt Systems collars operate on a low frequency FM signal and have the best range out of the many we have field tested. Many budget remote trainers operate on high frequency radio waves which are easily blocked by obstacles and terrain, meaning the signal may not always reach the collar when you need it.

If you need the 1600m range, but you have a mix of dog sizes, or working dogs AND pig dogs, take a look at the Micro iDT Plus collar which is compatible with the H2O Plus handset. (see comparison photo above). This is a lighter more compact collar that’s great for working Kelpies and Collies or smaller pig dogs that won’t be in the strike zone. Give us a call and we can customise a system to suit your needs.

DT Systems is from the United States and are one of the oldest dog collar manufacturers in the world, renowned for their innovative, professional standard dog training systems.

Your dog should be able to understand and carry out simple obedience commands before beginning training with the H20 Plus, approximately 6 months old on average.

To get the best life out of your training collar:

  • Keep the collar clean where you plug the charger in; grit and salt can cause rust to form on the charging pin and prevent the charger from giving the collar a full charge
  • Rinse the collar after it’s been immersed in salt water and dry thoroughly, especially where you plug the charger in
  • Get the maximum life from your collar battery by giving it a charge once a month, even if you aren’t using it
