This is the Planet Eclipse Etha 3 Electronic paintball marker. There are two versions of the Etha 3, there is a mechanical version called the Etha 3M, and this version called the Etha 3 (electronic). The Etha3 offers players an electronic marker platform that takes everything great about its predecessor a step further. It's sleek approach to ergonomics, coupled with some notable upgrades takes the Etha platform into a new competitive realm. Its quick-release bolt assembly makes a huge difference to accessibility and maintenance on, or off the field. The aluminum low-rise feed neck reduces the overall height of the marker for a tighter, more compact player profile. And the new aluminum blade trigger brings a sharpness and responsiveness only found on more expensive marker platforms. More capable. More purposeful. More competitive.
