Dive tracker/Underwater navigation

[Ernie Kovacs]

I'm looking for a device that will allow me to get back to the anchor line reliably, or to put on equipment I've left on the bottom . I've read a bit about "dive tracker". Any other suggestions.

I saw a system called Navimate that looks interesting, but still in development.

Thanks,

Ernie

The Electronic Navigation Console by Seacraft looks promising

While I am at heart a complete nerd for new and interesting technology and gizmos, getting good with a compass is your best defense for getting back to your anchor. I (personally) view this as technology to fix a problem that is really fixable by developing a skill set. Certainly there would be uses but for the everyday run of the mill recreational diver learning to use a compass is the easiest and best bet.

All of my above mini rant aside though, both of those items look interesting.

Yeah, I agree with the compass idea. But when I'm filming I lose track sometimes.

Met these guys three years ago on the "boot" water-sports fair, apparently they still lack a sponsor to launch the production.

How have they solved the problem that satellite doesn't work under water?

A spool or a line reel is a time tested solution.

If you prefer something more technical though, you could use three sonar buoys and echolocation: https://uwis.fi/en/ (it really works but the price tag might be a bit high for the application you describe)

If you’re doing something like long-distance scootering, handheld GPS in a camera housing on a reel can work. Send it up to the surface, wait a couple mins, reel back down, and see where you are. Repeat. Can set the backtrack function to give you a distance and bearing back to the start point.

It’s a total hassle and complete overkill if you’re just swimming. At that point, compass, reel, or a strobe on the anchor line are probably better solutions. Or if you’re busy filming and can’t really be bothered, bring along a buddy whose job it is to keep track of stuff like that.

Tagged, I for one, like the idea of using accelerometers to monitor / calculate position.
