Oan Power Ring (300, Ranged Proficiency): 

In the days of the original Green Lantern Corps, the Guardian known as Meadlux created a power ring specifically for the Guardians. An Oan power ring possessed the same capabilities as a standard ring, but was fueled by the internal power of its wielder and thus did not need to be recharged. Unlike the traditional Green Lantern Ring, an Oan ring did not contain the impurity that restricted its capabilities against materials colored yellow. The revelation that such a weapon existed caused a great schism within the ranks of the Green Lantern Corps. Officers who had lost close comrades due to adversaries empowered by yellow weaponry lost faith in the Guardians, some of whom, such as Galius Zed, Eddore and Kaylark even went so far as to turn their backs on the Guardians, coveting the rings for themselves. Another group of individuals who took an interest in the Oan rings were the space pirates known as the Free Lancers..In the Omniverse the ring may have lost it's properties, for the most part.  This ring is still capable of shooting green energy beams out of it. The beams appear to be fists made out of a green crystalline energy. They travel at the speed of an arrow. This can be used while moving, or with other moves. This is moderately draining, equivalent to a light work out when he uses it. Each blast has 5 seconds to cool down. It has a range of 75 feet. The ring was discovered somewhere in Camelot by Jack. While not an ideal power ring, the ring has been picked up by him because he needs one.

This looks pretty good how you described it here, range, a rate of fire/cooldown, speed, etc. Maybe add a beam width and bold the last few sentences though to make it easier for move approval, the first half is mostly lore. 

(Thanks Demetri for the feedback!)

300 OM- Tactical Echo- A tactical machine that Lucas or Echo can use to track enemies from 15 ft to 20 ft away.  The green screen can track enemies using heat signatures.  However, the louder it gets, the more the enemy can hear the ping  sound.

(Not sure if this can be considered fodder or not)

I would say you definitely are gonna need enhanced senses for this, as it would cover its bases. You would be able to describe it as this and take away the sound downside, but otherwise its just gonna fluff the power. No-go for a regular move, good as fodder for Enhanced Senses.
