You don’t say what kind of boat you have, but I believe, with the Humminbird, you have to purchase a second transducer if you want to be able to see the depth if you are running at more than a few miles an hour. Garmin has had older models that are very similar to current models on sale for months at substantial savings. With the Humminbird, map chips are not included and must be purchased separately. If your lake or pond is not included, you can create your own high definition maps with QuickDraw also included free. f you move up to the echoMap series, they include 17,000 pre loaded maps at no extra charge that I have found to be very accurate. You must have the Striker Plus series to get the Quikdraw Contours map creation software. You can see a track of where you have been but not where you are in relation to depth or shorelines. The Garmin Striker series of depth finders have GPS but no mapping. Second, in places like natural lakes and ponds, there is only rocks and weeds on the bottom which traditional sonar shows just fine along with better images of fish. First, down and side imaging do a very poor job of showing fish. Must be that new WalletScan™ technology!įor many, (like me) the downscan imaging is not a very valuable tool. It seems like all of these companies have directed their R&D towards our bank accounts. They also support Navionics SonarChart Live, which requires an active Navionics card. The down side is that it shares your data, but you can pay $100/yr to keep it private. If you want to manipulate/merge data, you'll need to spend either $199 or $299 for their AutoChart / AutoChart Pro software, which includes the stupid "zero line" card.Īlso BTW, Lowrance products w/ Insight mapping include the Insight Social mapping, where you scan a body of water, upload it, they process it, and add it to their social map, so you can add it back on to your card. If you want to store more, they make you buy a "zero line" card- a blank freaking map- for $100. My guess is that the Striker Plus series is more likely to have the down-facing element.īTW, my research indicated that Humminbirds only store 8 hours of AutoChart Live data. Whether or not they have changed the included transducer with their units will take some research. Here's the article I read which has the you-tube video demonstration completed. Has anyone else ever heard about this claim? Lowrance's parent company claims the patent rights and has sold licenses to this technology to all other manufacturers except Garmin. In order to overcome this gap it is claimed Garmin has to "stitch together" to two side-scan images to show you a "picture" of what is under the boat, only it's not the true picture because there is no downward facing element. However, the big concern is on a web article done by Lowrance which claims that Garmin does not have an element in the skimmer which faces down due to patent infringements and thus only has the two side scan elements which leaves a gap that the elements in the transducer can't see directly beneath the boat (this is only in the Gamin units which have the ClearVu or side-scan). In Massachusetts there's so many small lakes that are not any Navionics / LakeMaster chips so I really want to create my own and only Garmin and Humminbird have this capability, so I'm told and have found to be true thus far. It can now be launched through the Help Menu and is opened inside an AutoChart Live PDF viewer.I'm currently evaluating the Garmin Striker 7SV vs the Humminbird Helix 7 G2.
