The SportDOG SportHunter 1800 is an incredibly versatile training system and a good choice for all-around use. The low continuous stimulation levels and gradual increases between levels on the SD-1800 are particularly useful with sensitive dogs or breeds. You can customize your SportDOG SD-1800 to match your training preference. It comes set up in MODE-1 (an 8-level continuous + 8-level momentary stimulation one dog collar), but it can easily be changed into 7 different modes with different button configurations. This allows you to customize your transmitter to your training needs. You are also able to transform your one dog system into a two dog unit with the "Add-A-Dog" feature (extra receivers sold separately) and using the toggle switch on the transmitter. Features: Collar and Transmitter are Waterproof & Submersible. No external collar antenna to get hung up. 3/4-mile range gives ample training range. Push-button ON/OFF switch activated at the collar. Customizable transmitter settings. Choose from 7 pre-set modes. Up to 16 levels of continuous stimulation or 16 levels of momentary stimulation. Instantly change stimulation intensity from the transmitter with a fingertip dial. Tone only button. Built-in toggle switch so you can upgrade to 2 or 3 dogs later (extra receivers sold separately).

Rechargeable, user replaceable NiMH batteries in receiver and transmitter. Low Battery Detect indicators on both transmitter and receiver. Backed by a Lifetime Limited Warranty.
