Lowrance GPS Question?

**Cray** · 01-12-2012, 09:43 AM

ShilohRed, watched a video on computer a while back. This Guide in Ohio showed a trick he uses to mark spots and keep low profile. Take some 1in pipe insulation, cut off a 2 or 3 in piece and uses a half ounce weight to anchor it. They were pretty hard to see with the camera guy just looking for them. But if you new general area they were obvious enough to stay on your spot. Lot cheaper than buying new GPSs.

These are limitations of the satellite system, not the receivers we mount on our boats. Nothing these manufacturers do can fix the errors in the satellite system.

I think a lot of people are fooling themselves into thinking their GPS is spot on, every time. I've owned Garmin, Lowrance, and Hummingbird, with each one I've seen the coordinates move around with the unit sitting dead still. You can have the boat sitting on the bank, and the boat indicator icon is moving around on the lake map.
I think if folks did a little test, drop a marker buoy in the water, blind themselves to any outside visuals, only the GPS screen, then see how tight they can stay to a marker buoy. I can guarantee they ain't gonna stay tight enough to keep a jig from hanging in a brushpile, and probably not stay within a 10 foot radius.

This is true. However, ff you really gotta need to stay on a brush pile with a gps, get a Trimble handheld. It keeps you within an inch of your waypoint.

That is true. The Satellite sytem has a margin of error that cannot be overcome by any receiver.

We will have to see how deep Don's pockets are. Maybe he could be the guinea pig tester.

Maybe all the people who do not believe in HB's "wish list" function of "listening to their customers" should start a "movement" and contact HB with requests to remove the "HB Donut" from the HB "wish list" as (what you say) is a technological impossibility....

(Lowrance would be grateful for the added sales...)
