| I fished with a guy in sept that had a gps built in to his fish/depth finder. The detail was really cool --at least to a guy who has never even seen a GPS before. It showed his boat and the path it needed to travel to go over a hump. My questions -- How much does unit like this cost ? --I need reliability within a few feet - For my application I could get by with a hand held unit I guess , does it show a "boat" on the screen like a depth finder ? I need one to map open water humps and reefs in Canada . How much can I get by for , any suggestions ? MD |

Location: Davenport, IA | If you want to use navionics chips (lake maps) the lowest priced unit that I know of is the handheld lowrance h2o which is $170. It comes w/ a 12 volt adapter and takes the chips. But the chips are expensive ($200 for the HD version) |

| You can et by with a handheld but you will very quickly want to upgrade to a full sized unit as the screens on the hand helds are arather small. I would recomend one of the Lowrance units such as the 332 which has both the GPS and a graph on it. These units are being replaced with a new model next year (very little difference) and can be found for a steal of around $500 IIRC. |

| The lake I fish (manitou) has not been "mapped" I don't think . How do I find this out ? I guess it does'nt need to be mapped out for GPS to work does it ? What differnce does it make if a lake has a known map with islands hazards etc VS a lake that does not. HELP MD

I need reliability within a few feet
I'm quoting Lowrance as it is the only product I have used.
http://www.lowrance.com/Support/FAQ/gps_faq.asp#gpsaccuracy
With the elimination of Selective Availability, GPS accuracy is typically within 10 to 20 meters, and with the help of WAAS, accuracy can be well below 10 meters.
http://www.navionics.com/PremiumLakeList_06.asp?RegionID=5
lists Manitou in Quebec.
My Lowrance LMS480M GPS/sonar shows a triangle for boat location and direction as well as the trail. You have to be careful on the zoom scales and GPS accuracy. As for detail that a map might not show etc, I use MapCreate to add/remove GPS points, trails, routes, and more. It's pretty nice to mark the launch and lodge locations too.

Location: oak lawn IL | i have the lowrance 332c and love it. i also have the triangle to mark where i am on the map. the map will show you the breaklines,known humps and creeks as well as outher things and the gps will help you get close to where you want to be. mine seems to get me within 20' of where i want to be on my map.
where i fish the lakes are connected by narrow channels and when i'm going threw the channel my gps says i'm traveling on land.. |

| So does fishing a lake that has been mapped VS one that has not been offer any advantages for using GPS ? Sorry to be such a dummy but I don't understand all a unit can do for a fisherman. MD |

Location: Waukesha, WI | What the GPS/locator has to start with is basic land/lake info and no depth contours. The Navionics chip gives you land/contour detail by plugging it into the SD card slot(s). The MapCreate software comes with hotel, restaurant info, etc that can also be uploaded. Lowrance's web site is good for downloading model manuals and product simulators to get the feel of things before buying. |

| Dan,
You can make your own contour maps for your lake. Doc Sampson has been doing this for years, and with the help of Warren Parson's , even create contour maps that he overlays on aerial photos. He uses Fugawi and 3DField. You can purchase through him.
Doc holds several training classes throughout the Midwest. I consider myself pretty good with my Lowarance Sonar and GPS, but I learned a lot at Doc's class last year. Here's a link to his website. http://www.hightechfishing.com/home.html |

| Manitou Dan,
Nice to find someone who fishes the Manitou.
I have fished Lower Manitou with my friend who has an island in South Bay about five times. I looked all over the internet and found that Lowrance maps in this area are very poor. I've been using a Garmin 60c with Topo Canada map for the last four trips. It is incredibly accurate as far as the shorelines go, but has no contour lines in the lake itself. It also shows the names of most of the lakes we portage to along with bays and some island names.
I've been from the landing to Kamini to Aronson with no problems. If you need some Waypoints, let me know. I've marked many of the hazards.
