This Underwater Drone is AMAZING! Fifish V6 Review 

Yes the Fifish is incredible

Awesome

How much are they

I was thinking bottle rockers for mini torpedoes 😅

That sounds too rough for the drone

Go under the waves genius

@benmallahsstockbroker3752 yea but it will surface or you'll habe to swim out w eithrr way the guy answered its not mesnt for rough water anyways so its useless for beach dives

Looks like FLA, to me! Loved Diving the Oceanside CA. Rock Jetty, after Midnight. Pulled dozens of Lobster dinners outta' there through the decades! I was a Marine Stationed at El Toro, Camp Pen, and MCRD San Diego. Isn't an inch of coastline that I missed from the Border to Santa Barbara, Catalina etc. Miss that now, as I spent 32 years in Mexifornia, and dove most of the Baja Peninsula! 1979, and the next 32 years. I do miss blowin' bubbles and getting high on the Reefs of SoCal, for sure! Explored most all by boat as well. A lot of it with my 2001 MacGregor 26X PowerSailor! Owned since new. Best Dive platform, bar none! Doin' the Right Coast now,, including FLA.1500+ dives....... and counting! Now I am older than the "Old School" dude in his vids! HA! Gotta get me one of those drones! Great reviews, and practical uses and content!

Its for safety reasons

Wdym, drones only run for this amount of time usually, if not less. For its size and capabilities, I'd say one hour is great time for this kind of drone.

Great idea

Or possibly go to one of the Big Box Hardware stores and get the same length "Plastic coated cable" they sell and swage it to the drone's handle I say! The 1/16" will easily work, and the smallest Cable Ties available, unless the manufacturer already somehow did that perhaps? I see a lost drone if that cable, they use, is gone when sheared by something, or snagged perhaps, and pulled on too hard possibly? Only thing I see as a weak point, but not knowing what it is, that is how I would protect that investment! The BIG question, is this thing neutrally buoyant or negatively buoyant, and at what depths?
