Our expert's opinion

Photo de Arthur - OPS Store

"This replica is nice. The ability to program it with the MEDUSA is a big plus. It's very light, and the fact that you can trace both red and green balls without a module greatly enhances the realism of the game. "

Description

Theseus Medusa ETU PDW Tracer Poseidon AEG replica presentation video

The Theseus Medusa ETU PDW Tracer Poseidon AEG, a compact AEG replica with MEDUSA mosfet and integrated tracer.

The Theseus Medusa ETU PDW Tracer Poseidon AEG is an AR15 electric replica designed by Poseidon Technology Co, Ltd, a Taiwanese brand specializing in the production of high-quality airsoft replicas and internal parts. The result of a partnership with CSI, it features an injection-molded polymer design for durability and robustness. Its format favors compactness and maneuverability, with field-proven features such as folding sights, a PDW-type stock, Picatinny rails and M-LOK attachments on the handguard and upper part, for easy access to the weapon.the latter can be easily accessorized with optics, a tactical grip or a laser.

At the heart of the Theseus is the mosfet / ETU MEDUSA E.T.C.S, which lets you program your replica from an Android or iOS smartphone via a Bluetooth connection. It lets you configure firing modes (burst, full auto), activate the binary trigger, adjust trigger sensitivity, and manage plotter activation/deactivation, while ensuring automatic battery detection and detection of any faults. The electronics incorporate comprehensive protection against overvoltage, undervoltage, overcurrent, short-circuit and overheating, to ensure long-term security. Via the application, the "FIRE" function can also be used to trigger a shot remotely, without having to pull the trigger.

Internally, the replica is based on a 6.03 mm precision barrel and a Poseidon 8 mm reinforced V2 gearbox, providing a reliable base for regular use. It incorporates a Medusa AEG LED Tracer Hop-Up Unit directly in the Hop-Up chamber, compatible with green and red tracer beads, providing an immediate advantage in low light without the need for external accessories.

Thanks to its level of equipment, the Theseus Medusa PDW offers an excellent features/price ratio and is a particularly interesting option as a first replica, complete right out of the box and easily customizable.
