Underwater GPS
Pretty cool for around here to find mapped wrecks by scooter from shore.

The ocean is a lousy teacher. First you get a test, then the lesson.
Re: Underwater GPS
navimate is vaporware though, been several years.

Re: Underwater GPS
Not very exciting. You are tethered to the surface with a max depth of 75 fsw. This is something a home DIY enthusiast could accomplish

Re: Underwater GPS
Yeah, not thrilling.
Too bad Navimate looks like it'll never happen. That would be a heck of a cool gadget.

Re: Underwater GPS
The position information is collected at the surface so it is not actually the same as the underwater position. You can do the same by towing a gps on the surface time synced to a camera carried by the diver.

Re: Underwater GPS
Yep and that is an even more elegant solution but you still need to be tethered to the surface and you still don't get real time locational info to the diver.selkie wrote:The position information is collected at the surface so it is not actually the same as the underwater position.

Re: Underwater GPS
If the antenna is on a big enough float just pull down to take out the majority of the scope. That gets you into a <10ft circle of precision which nearly as good as GPS + WAAS is in the first place (<3ft 95% of the time). The problem is more the 75ft cable length and watreproofing issues with trying to split on a longer one. Also the diameter of the cable and how much drag it creates in current.

Re: Underwater GPS
Thats why I was figuring keep about 20ft depth, once on target, surface, drop a shot line, leave unit there. Now would be nice to be able to disconnect unit from antenna, throw in an otterbox, so at worse you only loose antenna. Or I guess something big enough to throw the whole thing in, and bring with you.

Re: Underwater GPS
There aren't that many sites where this is even warranted. Ben and John hit the Bomber from shore via a compass bearing alone. Its hard but not impossible. About the only site where this is even useful right now is the Dauntless off Golden Gardens, if you don't get mowed down by a boat getting there and back. Almost everywhere the dive flag and antenna is more of a liability than a help.
With our local charters struggling and the dubious nature of being a long way from shore in boat infested waters, you are better off investing in a few charters a year or a private boat.
