Garmin GPSMAP 421s 4-Inch Waterproof Marine GPS and Chartplotter with Sounder Reviews
| 54 of 56 people found the following review helpful  Awesome Chartplotter, best price at Amazon!, By Amazon Verified Purchase This review is from: Garmin GPSMAP 441s 4-Inch Waterproof Marine GPS and Chartplotter with Sounder (Electronics) If you are looking for a compact, user friendly GPS Chartplotter/Sounder; buy this one. Garmin is the best, most fairly priced plotter/sounders available. My only regret was not buying the 541s. That 1 inch make a difference. I've been on the water ny whole life and for the money the 441s and 541s are the best plotters available. Amazon has the best prices on them too. WOuld have recieved 5 stars but add and tech infor doesn't state how long the transducer wire is. I took a chance and it fit with some room to spare. Transducer wire is 25-30 ft long. I also recommend buying the transducer with speed and water temp. 33 of 36 people found the following review helpful  NO Map included/ don't like alphabet scroll when naming a position, By Amazon Verified Purchase This review is from: Garmin GPSMAP 421 4-Inch Waterproof Marine GPS and Chartplotter (Electronics) The description leads one to believe it has a U.S. base map installed. Unless I'm doing something wrong it has no map what so ever. Be prepared to spend another $99 to upload any kind of map. Yes, it is of good quality. Installation is a snap. Most of us will only use the ground and hot wire. More advanced installation will provide you with leads to your radio and other communication devices. Ease of use is good, you will have to page through a lot to find what you want though. One thing I really don't like is once you mark your position you have to page forward twice to name it then scrolling through the alphabet characacters is like pulling teeth. Don't get me wrong. I will rate it good for value, just remember you get what you pay for. If I had to do it all over I would spend the extra money for a better model. 27 of 30 people found the following review helpful Unit looks good, This review is from: Garmin GPSMAP 431S GPS Dual Beam Combo (Electronics) The unit has a nice clear screen that shows up well in any light conditions. I have the same problem with this unit that I had with my handheld Garmin. The Inland Lakes software does not properly show the location of the boat. It will display the boat skidding along on dry land when you are 200ft. off shore. This seems to be a problem with the way the software interacts with the unit. If you save the track to a computer, open Inland Lakes there, it will always show the boat in the water. Trying to explain this to Garmin support is like talking to my cat. I have had a lot of Garmin products and they work well for the most part, but, support is almost nonexistent. |
