SportDOG Brand WetlandHunter 425X Remote Trainer Gray One Size. Wrapped in Realtree Max-5 camouflage this model looks outstanding without standing out. Consistency and perfect timing are critical to developing your sporting dog so the remote is quickly and easily operated without having to look at it - which lets you focus on your dog and not your equipment. With only a slight movement of the dial and the push of a button you will be able to deliver a tone vibration or one of the 21 levels of static stimulation. Use these stimulation types to communicate with up to 3 dogs (with purchase of Add-A-Dog collars) out to 500 yards with any of the 425 models.SPECIAL FEATURESDesigned for the waterfowl environment with Realtree Max-5 camo finish Designed for ease-of-use and no look operation More levels of stimulation allow for more customized trainingRANGEUp to 500 yardsSTIMULATION RANGESUp to 21 levels of static stimulation with low/medium ranges Option to train with vibration and toneEXPANDABLE SYSTEMSupports training up to 3 dogsWATERPROOFWaterproof and submersible to 25 feet using DryTek technologyDOG SIZEFor dogs 8 pounds or larger with neck sizes 5" - 22"BATTERIESRechargeable lithium-ion batteries Charge in 2 hours last 50-70 hours per chargeLOW BATTERY INDICATORYesCONTENTS Remote Transmitter Receiver on 3/4" Collar Strap with Realtree Max-5 Camo Finish Charging Adaptor Standard Contact Points Long Contact Points Lanyard Test Light Tool Operating Guide Basic Training ManualPRODUCT DIMENSIONSReceiver without strap - 2.60"L X 1.30"W 1.23"D Remote Transmitter with antenna - 5.30"L X 1.70"W X 1.00" D Specifications for SportDOG Brand WetlandHunter 425X Remote Trainer: Manufacturer: SportDOG Color: Gray Size: One Size Battery Type: Lithium Ion Water Resistance Level: Waterproof Quantity: 1 Range: 500 yds Included Accessories: Basic Training Manual & DVD Additional Features: Remote Transmitter Package Contents: SportDOG Brand WetlandHunter 425X Remote Trainer SportDOG SD-425XCAMO: Brand WetlandHunter 425X Remote Trainer Gray One Size
