SportDog Field Trainer Remote Trainer - SD-425E

The New SportDog SD 425 is the updated model of the very popular Sportdog SD-400. The Sportdog SD-425E does have an increased range up to 450m and a couple of added features such as vibration and tone function and lithium-ion batteries. The collar will suit a dog from 5 kgs and up and can control up to 3 dogs at one time (with extra collars added) which makes the Sportdog SD 425 E  the perfect short range field trainer for pets, farm or hunting dogs that can push the boundaries.

The Sportdog SD425E uses SportDogs DryTek waterproof design which ensures the unit is fully waterproof and submersible up to 7m and is fully rechargeable with Li-ion batteries that have a fast 2-hour charge. 

You can customize both the collar and the handheld transmitter. The collars have a low setting for sensitive dogs as well as a medium setting for hunting, working or stubborn dogs. This feature is set on the collar which allows you to customize the collar to suit the dog wearing the collars temperament. The handheld Transmitter can also be customized and comes set up in MODE-1 (an 8-level continuous + 8-level momentary stimulation one dog collar with a non-stimulation tone or vibration button), 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.

Remote Trainer

12 March 2018
Having trained all our own dogs from puppies over the years which took time & patience I was very sceptical about the new technology of trainers that are available today.We got a 2 year old collie x from the SPCA recently that had been ill treated, the dog called Tip had know issues apart from needing training most of which he excelled at except his recall & attention to our livestock on our lifestyle block.So reluctantly decided to purchase this remote trainer after a lot of research, when it arrived I set it up & took Tip out in the paddock & was amazed if used correctly how quickly he responded to recall.I now hardly ever use it for recall now but will continue to use it for other training if necessary.I must emphasise please read the manual online to use this product as it should be.Great training aid quality product & good advice from Jason Thanks.
