The Magnum and PULSE injector kits seem very similar, as shown in pictures and videos. A few key differences and feature variations explain the price difference.

• While both models have their origin as a veterinary tool, the Magnum is better engineered and manufactured to a higher standard.
• The Magnum is built heavier yet more comfortable in the hand and will hold up better after extensive use.
• The PULSE has an adjustable gasket tension, while the Magnum depends on more precise machining and less tolerance to operate efficiently without needing adjustment.
• The Magnum has four different accessory configurations, while the PULSE has only one option.
• The Magnum injector is manufactured in the US, while the PULSE is made in China.
• Both have 1-5 ml dose settings by a dial, and both use a ratchet system to advance the plunger.
• Both come with o-ring replacement kits for the needles and plunger.
• Both have replacement parts available and are guaranteed for one year.
