LongShot G3 HD


 Rugged, refined, reliable.





 Everything you need to run your Hero3 or Hero3+ (Black, White, or Silver) for as long as you want, from any DC power source!  The system accepts any DC voltage from 5v to 24v, and comes with three connection options: Cigarette plug, battery clamps, and ring terminals.  The generous 15-foot power lead allows plenty of flexibility in installation.

This is the same system that NASA used to monitor the splashdown of the Orion spacecraft, the U.S. Navy uses in waterborne drones, and <un-named> used to improve Navy Seal Team landing craft.

The LongShot uses a Battery Eliminator that occupies the GoPro battery compartment.  The Eliminator snaps right into the camera like a regular battery.

Installation is as easy as inserting the Battery Eliminator and swinging the door closed.  Power is delivered exactly how the GoPro Engineers intend:  Via the camera’s own battery contacts.


The LongShot G3 ‘HD’ is our ‘Heavy Duty’ system.  This means that your camera and the LongShot are waterproof, all the way to your power connection.  You can expose the camera to the elements, even run it underwater.  The HD is ideal for applications on boats, trucks, planes, helicopters, commercial vehicles, etc.

Our system does not use the camera’s USB port to deliver power.

The USB, for a variety of reasons, is a poor choice for powering the camera.  Thousands of users have discovered this fact, much to their dismay, after losing footage or overheating their camera.



In-vehicle cameras are becoming very popular.  Having a secure method of recording your travels can be incredibly valuable.  From establishing ‘fault’ in insurance cases, to unexpected once-in-a-lifetime events, to interactions with officials, a reliable recording system can pay for itself in a few seconds.  The LongShot HD is ideal for this application.  Mounted on your dash, powered from a cigarette socket or connected via ring terminals directly to the battery and controlled from a smartphone, this system is an awesome way to be sure you don’t miss a thing.  If you want to do this, consider having us machine microphone holes into your housing for cleaner audio.

To the best of our knowledge, there is no other power system like the LongShot G3 (at any price).  For a durable and reliable power solution choose Hardened Power Systems and choose the LongShot G3.
