Three Models for Three Training Situations
GT-1 Gentle Trainer for Sensitive Dogs: Single Button Simplicity 15 Levels of Adjustable Vibration (No Shock) adjustable on-the-fly	GT-2 Gentle Trainer for Active & Sensitive Dogs: 2 Button Simplicity Button 1 same as GT-1 (Adjustable vibration only) 2nd button - 15 levels of adjustable vibration (momentary), each followed by its own level of controlled e-stimulation that reinforces the initial vibration guidance. Momentary vibration followed by additional 15 levels of controlled e-stimulation provides more training options for different dog temperaments.

Vibration is a great feature with many different applications. Many of our competitors use a tone feature that makes the collar unit emit a quiet beep. We feel that Vibration is a more effective alternative because your dog is the only dog that will feel the vibration (other dogs can hear your dog's tone and your dog may hear another dog's tone command, which may cause confusion). Like with most humans, most dogs will also lose their hearing as they get older so it will become increasingly difficult for them to hear the audible tone, but they will always be able to feel the Vibration feature. Also, your dog will be able to feel the vibration when the collar unit is submersed under water if he ever decides to go swimming. The tone from other collars may not be heard if the collar is under water. Depending on how you train with it, Vibration can be a warning, a command, a way to get your dog's attention, a substitution for stimulation (especially for sensitive dogs), or even a reward just to name a few uses.

The Jump Stimulation* (1830 model) is a great feature for training methods that involve “jumping” frequently between two different stimulation levels. As before, you can set a level of intensity to the Nick or Continuous Stimulation buttons that is appropriate for training your dog. The Jump Stimulation button allows you to set a second, self-programmed stimulation level higher or lower than your normal intensity level setting. Applying a correction at the right intensity level quickly and timely is paramount in dog training with e-collars. With the Jump Stimulation feature, you won’t have to have to fumble around with the stimulation setting at the time that the correction is needed, so the chances of applying a stimulation too late or at the wrong intensity level are virtually eliminated. The Jump Stimulation is also useful in emergency or dangerous situations when your dog is excited and not responding to the normal stimulation level. If you do not have time to increase the intensity level in these situations, the Jump Stimulation is a fast and convenient way to get your dog's attention before the situation gets out of hand.

* The Rise Stimulation button (1830 model) continuously increases the stimulation level until the button is released. This allows you to hold the Rise button until he/she notices a response from the dog, essentially allowing the dog to choose the appropriate level of stimulation. Prior to the Rise Stimulation, dog trainers had to guess at the correct stimulation level for individual dogs. With Rise Stimulation, the dog responds to a level that matches his temperament.

All H2O 1800 series models have an 1800 yard (1 mile) range and come with completely waterproof and rechargeable (Ni-MH batteries) transmitter and collar units. Nick and Continuous Stimulations come standard on every model in the H2O 1800 series line-up.

The H2O 1850 comes with a Beeper/Locator, which is controlled from the handheld transmitter and is audible from up to 450 yards away. There are 3 functions: Locate, Run & Point mode, and Point Only mode. The Locate button will make the collar unit beep any time it is pressed to help you locate your dog. The Run & Point mode will make the collar beep one way while your dog is on the move and another way when he stops to point. The Point Only mode will make the collar beep only when your dog has stopped to point.
