Hey guys, I have recently delved into some nearshore wreck fishing and am trying to compile some decent GPS #'s.........Have you guys found these #'s to be accurate? It seems that you can pull #'s for the same wreck name from different web sites, and all of them have slightly different #'s. Thanks for the info.

The ones i have tried on there are off, Jamie (racn35)has a chart over at the tackle shop that has # on it , and he has checked them with his unit and says they are close.

Most are not good #'s. They are in the general area but it will still be like looking for a needle in a hay stack tp really locate a wreck. This based on the GPS side. I do not know about the Loran. Your better off getting them from a dive book or dive site they tend to be better.

I have most to be very accurate. I have also found some people do not use the correct format when using their GPS i.e. 35 degrees
15 minutes and 45 seconds is also the same as 35.2625 degrees. You may need to change the format on your unit.

You can answer your own question there Bill. Look at the list. There are several wrecks that have 2, 3 or 4 different sets of numbers for the same wreck. And most times those are pretty far apart, far meaning MILES. I don't know how persistant you are when you go hunting, but I would say most times you aren't going to find a wreck unless your number drops you within .1 nm of it. If youre really persistant you might find something when you land withing .25 miles of it, but that is going to take a lot of time running lines or circles and watching your bottom machine.

The Chesapeake Angler list appears to be a compilation of several lists from different sources. I can tell you a lot of those numbers are LORAN conversions from Gary Gentiles book. LORAN conversions are no good. You won't be able to find them because in most cases they are too far off. Around Cape Henry you might get lucky because they almost zero out there, but the further east you go the worse the variance gets. As long as we are talking about variances lets get the DGPS and WAAS out of the way. If you take a number from one format machine and put it into another format machine, ie WAAS GPS to DGPS GPS or vice versa, it is going to be off. Not terribly off, usually leass than 100 feet, but you are going to need to look a little bit unless it is a really big wreck.

Your best bet is to keep every number you come across. Get them in some sort of a data base so you can sort them and keep track of where they came from and if you know they are good or not. Then get them all in your plotter. That way you know when you are near something and can take a few minutes to look for it. Having a list squirreled away somewhere will do you no good because you'll never look for the numbers, if they are in your plotter you will eventually look. Having the data base and the source helps you out since you can check new numbers pretty easy to see if they are in there, plus you'll know if they are good, bad or unknown.

There are a couple of numbers on that list that are dead on, and handful that are close but most that I have knowledge on are too far off for you to have any hope of finding them.

I sold all the charts and some one stole the unit off my boat......
now I get all my numbers from Darren


But I do have another source that has 1000 and every one is a dead ringer number you can bet on~

Can someone elaborate as to what this all means. I hope to learn something as I often do on this site.

Thanks

Latitude and longitude can be expressed in several different formats.

Degrees-minutes-seconds looks like 35*15'45", where the minutes and seconds range from 00 to 60. This is annotated as dd*mm'ss

Degrees-minutes-decimal minutes looks like 35*15.750', where the seconds have been converted to a decimal (i.e. 45/60=.750). This is annotated as dd*mm.mmm'

Degrees-decimal degrees looks like 35.2625*, where the 15.750' has been divided by 60 to get the decimal portion of a degree. This is annotated as dd.dddd*

Degrees-minutes-decimal minutes can also be shown as ddmm.mmmm, where our working example would be 3615.7500.

As noted above, you need to see how a LAT/LONG is formatted, then either convert it to the format you are using in your device, or change the format selected on your device while you are inputting the numbers.

Note that I had to use the asterisk * to designate degrees, because I can't make the superscript symbol for degree.

YOur soooooooooo right. Just remember, give a wreck number away, and u give it away forever. Even those who promise never to give it to anyone else, will. Kinda like when u get married and promise to love honor and obey.........for a little while anyway. Capt. Joe

This problem is exactly why I didn't put GPS numbers in my Chesapeake Guide, and hesitated to put them into the Mid Atlantic Guide then spent a lot of time explaining that when you plug those numbers in, you won't end up exactly ontop of a wreck. Different datums is usually the biggest problem, but even when you plug the same numbers into two units set to the same datum, you can't expect to get dead-nuts-on. I tell readers that when they use the numbers in Rudow's Mid Atlantic Guide (which are all verified GPS coordinates) they need to plan to go to the spot, mark it on their unit, then run a circular search pattern to find the structure, wreck, or whatever. You'll be in the right neighborhood, and 1/2 hr or so of searching should do the trick (large items, like the Hot Dog, are big enough that it won't take any time at all, but small wrecks and the like are tougher.) If you're gathering varying numbers for the same wreck from web sites & such, plot them on a chart, then plot a spot in the middle of the cluster of marks and start your search there. You shouldn't be more than 1/4 or 1/2 mile off (or some of those numbers may in fact be "bad.") Good luck!

Just for fun - some of us divers move a wreck every now/then :D.Couple big air bags and off she goes :pp.Kinda like hide/seek :yes:.

A lot of "numbers" are given out to a wreck.The first guy never checked on them and soon they are in 5-6 books/printouts.Heard/read enough times- they become "good" numbers.

Watch your meter when running - you'll find some good stuff.If your radar overlays with your GPS - you can home in on an anchored boat from a mile or two and then go back later to check it out.

I've found some wrecks over a mile away from the printed numbers - most are close but not dead on.

I can't remember where, I think it was thehulltruth.com, someone was relaying a HO story....HO brought a friend. Not what the captain had intended but he allowed it. Turns out the 'friend' was a chater captain, who brought a handheld GPS and stole all his 'secret' wreck numbers. Came back the next week to fish and found that guy on the wreck with charter.....

:eek2:

I'm ready to start trying some wreck fishing this year, especially over the next few months for Tog. I'll be looking for good HO's to help a newbie out.
