Educator collars are lighter and more technologically current. Educator's tapping sensation is twice as intense as their pager mode, their tones are more pronounced, their stimulation is cleaner and has a higher intensity when needed. The stimulation dial on the Educator is easier to adjust and has the "lock and set" feature to prevent accidental over-stimulation, for 2 dogs each dog can be locked in to a different level. Educator's stimulation is of a medical grade type that does not cause head jerking but will obtain compliance. All of Educator's products have night lights with one exception, the ET700. They have programmable modes allowing the user to select different uses for the buttons. All of the Educator transmitters float and are waterproof to 500' and can withstand 5000 Gs of shock. Comparable e-collars are good to 60' and 1000 Gs of shock, tough but not as tough. They have a quick-release belt/saddle/purse clip combined with the ergonomics of the transmitter make it easier to work. Educator uses Biothane collar straps for unsurpassed durability. Comparing similar e-collars in other brands to the ET300 is like comparing a Yugo to a Ferrari but paying the same price. Last but not least, the money is staying here in the US, all Educator collars and products are made in the USA.
