Model: | ALL SI Models |
Suggested Upgrade: | Unit loses GPS signal at slow speeds - Below .6 mph |
Explanation: | When I am in navigation mode, my tracking arrow goes away and is replaced by a circle (Donut) at speeds below approx. .5-.6 mph. This makes it extremely difficult to hold the boat on underwater brushppiles, etc without the use of marker buoys (or a competitors GPS unit). As I understand it, this problem could be fixed with modified algorithms through a firmware update. It would be a good idea for HB to address this problem soon because it is costing them a great deal of money in lost sales and referral/repeat business from current customers like myself. http://www.crappie.com/crappie/fishing-electronics-trolling-motors/ |

hay yall. i guess that it would be better for the directional arrow did not change to the donut ,but my Garmin gpsmap76csx doesn't do very well at that low speed that yall are talking about.i think the reason that hummingbird uses the donut is for that reason.i don't no about Lowrance. the gpsmap76csx is a high in unit with the electronic compass.if i don't keep a little movement with my boat then the Garmin starts to move around to much to stay on a brush pile. i have to get up a little speed an approach a brush pile ,then when i get over it i will drop a marker then just turn th Garmin off.when i want to go to another one i turn it on and start moving at a steady speed. i think the only difference in the Garmin and my hummingbird is when I'm going at this very low speed ,the Garmin just kind of jumps all over the place not really knowing what to do while the hummingbird changes to a donut and waits for me to start moving a little faster.hummingbird will probably change this in a future update,but i don't no if this will help because it will be lost just like my Garmin until i move at a higher speed
Moose, the Vista is pretty much about as entry level as it gets, I wouldn't want to base any comparisons of my high end bird on that unit. My 997 has a more powerful external antenna and much better tracking ability. In fact, I actually misnamed this thread, the unit is not actually losing the GPS signal at slow speeds, it is just not programmed to track/predict directional movements at speeds below .5 mph. That is why the pointer turns into a donut at that time, the unit will still show your speed and coords as you drift aimlessly. The highlighted part is a direct quote from a HB employee, this could be corrected with some programming and updated algorithms as I have stated many times. Let's stop beating the old horse here, hopefully HB will get the message and take care of this for those of us who know they can do better.

I keep up with several forums in order to learn as much as I can about my new HB.
These guys are beating this thing to death everywhere. Apparently they think if they keep it up HB will eventually have to give this thing attention......I think it is having the opposite affect.
I personally think there are several things on the wish list more important than this and am really tired of all the whining. If I was in charge of the prioritizing the wish list I would put it on the bottom of the list.
It is on the wish list......stop the whining. >:(
My experience with this is that the actual trail laid down while in the slow speed mode is exactly correct. There is never a large "jump" in your trail when you speed up and get your directional arrow back. just movement of the map to coordinate with the direction headed.
Perhaps when it goes into the slow speed mode, the map could be programmed to "lock" at that time also, so it doesnt spin around. I feel the spinning is more of the problem than the circle.
Using my Garmin and standing in one spot the bread crumb trail will not lay down a new bread crumb unless I move a certain fixed distance. So the map view will show me stopped in that spot for the time that I stay there.
I can use the Garmin Computer Software Program and look at the bread crumb trails and click on each bread crumb or waypoint and it will tell me the GPS location and time it was laid down on the computer.
Try taking your unit in a car and hook it up with the gps antenna and a power supply and set it up to leave a bread crumb trail. I can trace the path of my truck when I go to the lake and back. When I get home I can download that trail to my computer and see all the bread crumbs and locations on the computer screen using the Garmin MAPSOURCE computer program.
My .02 worth,
and yes, I am also tired of the whining about this
