hi all,
looking for a dive beacon / marker to keep an eye on my dive buddy (and vice versa) in low vis environment or night diving. Also, when diving with my daughter, she gets easily distracted and can follow a fish during a night dive, so i need to make sure she is in my field of view. I only dive recreationally down to 40 meters.
Budget <$50 ea ideally unless there is something unanimously superior that's more expensive. Ideally should last >10 hrs, preferably >20 hrs. I believe flashing light is forcing viewer to pay attention to it more (from my neuroscience background) although for the same reason can be potentially distracting. The goal is for the light not to be too distracting yet visible. I believe non white light that's bright enough might fit the bill.
Based on my search around i've found the following items (only compiling it here for posterity). It's not all inclusive by any means. Hope this can be of use to others looking for the same in the future. Please, give opinions from personal experience. If you use and love something outside the list, please share. May thanks in advance.
