just a quick you tube vid of my first attempt at fishing with the Mavic Mini, great weather helped us achieve a drop over 400mt out from shore. no fish but a successful day. you an see the bait release at the 1 min mark. enjoy.
This is a dangerous operation and shouldn't be considered routine. Lots of things can go wrong, If the spool binds up - you crash. During a long hard pull there's usually no indication before performance limits are reached then a crash results. Quick stop deceleration can cause the line to foul with the rotor then crash a crash results. Full disclosure, if I avidly fished, I'd probably risk swimming with my mini just because external loads are fun.
