A handheld GPS unit aboard an in-flight plane. Note the speed and altitude. WAAS signals are being implemented because of aircraft navitation needs.

DGPS vs. WAAS: What is better in a GPS?

Dear Capt. Paul:

I am now running my Global Positioning System unit mated to a DGPS receiver while in offshore locations, but I am considering getting another GPS unit that I would be using in interior lakes away from the coastal waters. I am also considering one of the current handheld units offered.

I would like to see a comparison/discussion on DGPS vs. WAAS accuracy, and is WAAS available for all of Louisiana Mississippi and Texas? As you know a separate DGPS receiver can cost more than what several standard GPS unit would cost. Plus, the connecting cables make it a little inconvenient.

I would like to avoid that situation, if WAAS is as accurate.

Mark your home by walking out your front door and using a GPS.

Use your GPS for marking an SOS location

Naturally, if you get lost or stranded and have a GPS unit with you, it can be used to capture your position and forward it to a rescuer.

But suppose you don’t have a unit and there is an emergency?

Don’t lose that favorite fishing hole by losing your data in a GPS crash.

Backup, backup, backup

There is hardly a week that goes by that I don’t get asked what can be done to recover lost waypoints, tracks and or routes from a crashed or broken GPS unit or to enter waypoint data into a newer of different brand unit.

My first question is, “Did you make a backup of the data that was/is in your unit?”

Ask Capt. Paul: How to get from Empire to the Empire Jetty

Dear Capt. Paul:

Can you or anyone give me an idea of the safest way to get to the Empire jetties from the Empire marina boat launch? I’ve never been down that area before.

Is there a way that everyone goes? I’m 100-percent unfamiliar with this area and would love any advice you guys can give.

Finding the mouth of a pass in bad weather can be difficult if the datum you’re using sends you to a different position.

DATUM settings in your GPS can be critical

I frequently get questions why a reader can’t find a stated position or a position a friend provides or why their GPS position information is not the same as their friends when both units are at the same position.

Turtle Bayou and Orange Grove are known for bass and other freshwater fishing.

Turtle Bayou and Orange Grove

Dear Capt. Paul:

I have been the target of several jokes about fishing the Turtle Bayou and Orange Grove fishing area for freshwater fish. My “friends” keep telling me that I would need a very good mapping GPS unit supplemented with aerial or topographical maps to find my way in and out of these areas.

The Red River offers anglers with a variety of options, but do your homework because there are few service locations along the pools.

The Red River - This top bass fishery has a lot to offer anglers

Dear Capt. Paul:

Where is the Red River Pool? Do you have a GPS coordinate for it?

While GPS units are great, you should never rely solely on that technology when in the field.

Use your GPS while turkey hunting

Turkey hunters who own handheld GPS units have a great advantage over other hunters.

Handheld units have a big advantage over smartphones in that they are designed around the GPS module and do not add the GPS feature as an afterthought.

Get the most out of your GPS

Hardly a month goes by without me getting a question about how to transfer GPS waypoints from one unit to a newer model or what to do when a GPS unit has crashed.

You can transfer navigation routes from your iPhone to an HDS unit, if you know the steps.

From app to onboard GPS unit

Dear Capt. Paul:

I run the Lowrance HDS-2 with the Navionics card, on my boat and I have the Navionics boating app on my iPhone.

If you can, purchase all the accessories you might need when you buy a GPS unit — you might not be able to find cables and transfer programs down the road.

Get accessories for your GPS unit now

I have been getting more and more requests to assist readers with finding parts and accessories for their GPS units.

There are many fish-rich targets off the southeast Louisiana coast.

Venice offshore platform fishing

Dear Capt. Paul:

I am a native of Louisiana currently living in Texas. I have a Texas registered 28-foot boat with twin 300-horsepower Verados with joystick steering.

I want to tow the boat to Venice to take my uncle fishing offshore for tuna. I’m looking for Thunder Horse, Diana and Hoover coordinates, if you have them.
