Gannet Sport DJI Phantom Series
This fully mechanical purpose built drone release system is the worlds smallest by a factor of 7.
Weighing only 13g, so small that it does not interfere with any of the drone sensors that the VPS remain unobstructed and active.
Instantly releasing any bait/lure load as soon as the load set point is surpassed by the smallest of margins. If trolling a lure with the drone it will release upon strike.
If you have a reel jam it will drop the load, if your line gets caught in the waves the drone will pull free so now you can fly with confidence.
