Also, for some reason, this made me think of Goldeneye...

Best FPS of the day!

Ever seen the cat fishing folks out on the east coast?  I've seen one guy using up at 8 rods  almost no one less than 3.  I often wonder if they have more success or not, figuring if the bait is in the zone, more is just more choices. 

Hello Hello!  Once you reach 10 posts you can post in classifieds section. Often people join just to post something for sale, so we restrict it to avoid that. But you seem to have joined a long time ago, and posted a few times, can easily get you up to 10 here and move this to classifieds.  Where did you get your T160 from?

I didn't see a response but if you have an updated file for the 20 fathom track Ill try uploading it to navionics!

Send me a DM and I'll send it to you

Those aren't dd-mm-ss, they are dd-mm.mm

It is measured in tenths of minutes, not in seconds, if that makes any sense.  GPS is silly sometimes - many different users (ships, sailboats, airplanes, car navigation, etc) use different integers to depict the same position. Most common that I've seen are: dd.ddddd (Google maps and a lot of terrestrial users), dd-mm-ss (sail boats, some charts), dd-mm.mm (most commercial mariners, most navigation charts). There are also a few other systems with specific ideas that not many people use.  Most modern devices let you choose which system you are most used to, between the three that I exampled anyway.

"Should the last part of the latitude (39°25.53'N) be entered as 053 or 530? Or what?"

So what's the answer? The navionics app, for lat. has 2-digits in the first spinwheel, 2-digits in the second, and then there are three more spinwheels with 1-digit (0-9) in each. See my post above for the screenshot. Do I have to do a conversion from dd-mm-ss to dd-mm.mm before entering into Navionics? But then the number of digits in the interface is 7 instead of 6. So confused.

I finally got it figured out. The way-point map on the CDFW site...
https://wildlife.ca.gov/Conservation/Marine/Groundfish#287201301-20-fm-line

... lists two lat/long coordinate formats for each way-point:

lat_dd/long_dd (aka Decimal Degrees)
lat_ddm/long_ddm (aka Degrees Decimal Minutes)

Neither of which were the format I was basically familiar with (Degrees, Minutes, Seconds) and I had no idea there were other formats in use.

The Navionics App uses ddm, but it's confusing because they don't label it as such and they have 3 digits at the end of the number string on their coordinates-input screen, while the coordinates provided by CDFW only have 2. For example, for a CDFW-provided 6-digit ddm longitude of 39°12.19'N, Navionics has 7 characters to select (with only the 6 provided by CDFW), and then the question is what to do about that. The answer turns out to be just use a ZERO in the last position/selector.

Issue solved.

Glad you got it sorted out. It's all about using the same units on both sides. 

I created the 20fa line GPX file from the DFG data, converting it as you mentioned:

I'm working on another converter (lost my original) to make them into Navionics format.  Should be ready today.

I've got a trailer that came "free" with my HobieCat, with no license or registration.  Prior owner said he had tried contacting prior owner but was never able too.  Would anyone have advice on how to remedy this, I'm not even sure I can read numbers off the trailer or not (will check next time I visit it).

Wow an active catfish bit a swimbait?!  Crazy!

On CBS this morning they were talking about it and mentioning that some commercial crabbers participated in a time release buoy deployment system trial and that they were happy with the results.  Trying to lend credibility to the plans they have mentioned in prior statements as a possible solution.  Sounds expensive, but would allow longer seasons.  Still costs will go up either way I'm sure.
