PDA GPS Receivers...
Do you use an external antenna with the Navman? And how does it
track compared to the Garmin? I had the Navman at first and was happy with it. Then I got a Bluetooth GPS (Emtac although there are many others). The Bluetooth GPS is vastly superior in time-to-first-fix as well as accuracy. There are a couple of web sites that give reviews of GPS devices and compare them. Check out http://www.gpspassion.com/en/hardware/gpslist.htm for a pretty complete table. From that table, you can link to reviews for the different devices. |

Knowing how computers crash, including PDAs, we back up The Cap'n on
the notebook with a Raymarine RL70CRC Plus chartplotter and keep our paper charts running by using a Yeoman that I disassembled from its foam portable laptop and stuck to the bottom of the mahogany chart table lid on Lionheart, an Amel Sharki 41 ketch. You guys ever see a Yeoman? I know where there's one for sale for $150, real cheap! http://www.yeomanuk.co.uk/prodmar/sport.htm You can plug the cheapest GPS into its data input and it will put your position dead on the spot on any nautical chart after a simple 3-point calibration. It doesn't require any special charts at all. The calibration scales the Yeoman to any size chart. After calibration, when you move the puck around on the chart, its target lat/long is displayed on the LCD. Press one button and you can make a waypoint or a series of them to make a route, just like these little, hard-to-read gadgets. Press another button and it goes from lat/long (x,y) to azimuth and distance (polar). You can measure from your GPS position to where the puck is by simply looking at the display....course and distance. Big difference is you have a permanent paper chart already plotted. No copying is necessary. Yeoman accuracy is the width of your pencil you put through the hole in the puck. Many commercial and military interests across the planet use them. Works great! On Lionheart, I have the Yeoman's output hooked to my network multiplexer so you can create waypoints on the chart and it shows up on the Raymarine chart plotter at the helm on the radar display and on the Dell Latitude notebook's The Cap'n, wherever it is sitting because I have it on a wireless LAN running virtual serial port drivers in background. An RS-232 to Ethernet adapter ($149) feeds the boat's intranet via a Netgear wireless router....(c; We love our toys....

I'm speaking of the iPAQ series PDA/handheld computers and the Navman GPS receiver with the Maptech charts. On Sun, 04 Jan 2004 03:19:51 GMT, (Larry W4CSC) wrote: Wow! That costs about the same as a Beneteau Bavaria....(c; Almost :-) Seriously, I saved money. "Final Step" has a fixed mount Garmin 162 mapping GPS. I wanted color. A 176C + memory card + what I needed with Bluechart would have been $2,000. I already had the Maptech charts I needed. Cost was $600 for the IPAQ - I think they're down to about $400 now, and $300 for the Navman with Pocket Navigator. I already had a couple 256M Flash Cards, but I think they're about 50-bucks. Works out fine. The 162 has Waterways and Lights and talks to the autopilot, the IPAQ right next to it has full color "regular" charts. Rick S/V Final Step http://www.morelr.com/coronado/ |

The whole GPS is built into the little antenna mounted next to the helm out of the weather. They have SeaTalk and NMEA models that simply put out all the statements. Accuracy is 3 meters! Click a bouy as a waypoint and the boat will run right over it.... |

Works fine in the cockpit (sailboat) and below (fiberglass sailboat) :-) Both are "right on"; both are WAAS. Having said that, there are some charts/maps on each that are off here and there. Not the same ones necessarily. Consistantly off exactly the same, so that says it's the chart itself, not where the GPS's think they are. Rick S/V Final Step http://www.morelr.com/coronado/ |
