    Default XI5/ Gateway yard test, not good


    Guys,
    I was having trouble with my XI5 putting me exactly on a know brush pile when I sent the info from my HDS unit to the XI5. Basically, I'm picking a way point and telling the TM to go there.
    It seemed like it was off and confusing me on the water.

    Well, I did a yard test pulling the boat with a tractor.
    Dropping a hat, giving it a way point , telling the TM to go back to it and following the TM as it rotated and spun.
    Bottom line is it's 9-12 ft off consistently from the hat. Not good news for a brush pile fisherman. (me)

    However, the good news is the XI5 was staying well within 5' of the hat when I marked it with the Anchor feature or memorized it's location with the remote. Incredible technology.

    So there it is. For now, I would not buy the Lowrance Gateway cable again. It's not accurate enough.
    It could be that my unit is a fluke and simply not working well.
    I did recalibrate it,
    Also, could be that if I had a 1 Point GPS on my HDS, it would work better.

    Perhaps in the future, there will be updates to the Gateway that improve it's accuracy.

    Also,
    I'm open to tips on how to make it better. For now, I'm out of ideas.

    thanks

    I suppose I could go back and give my way points new positions that would work accurately with the Gateway.
    at least the brush piles I use a lot.
    I could call it a number and a letter to let me know what it is.
    example, way point 1 would be the original mark where the HDS knows it it. Way Point 1A would be the HDS mark for the location that is correct for the XI5 with the Gateway.

    Last week I was on the lake and twice I monitored it intently. I parked by trees for reference and the Xi5 kept me within 2-3' for 10+ minutes both times. In playing with it, I marked a waypoint by another stump then fished away from it. When I told it to go back to that waypoint (probably 30 yds away), it got within 5'. Don't know if the Xi5's shipped with different software or not. I ordered mine early March.

    I agree and you would have to use WAAS to get it that accurate.

    Mine is very, very accurate by itself.
    It's only when I send it to a way point from my hds unit that it fails.
    Somehow the hds and ix5 have a different idea of GPS coordinate s.

    And we always need to remember that brand GPS specs are listed as "x-ft 95% of the time" ...

    That means the other 5% of the time ... Uh oh ...

    I have no need for the gateway at this time. But you can hit your menu twice then down to Satellites and there is a number that indicates your accuracy. I've noticed that if I'm connected to WAAS it will be in the 10 feet range or less, if not then more like 20 to 30 feet. As far as returning to a brush pile I can get dead on it most of the time as long as I zoom in while going to it. (zoom to 100 to 200 feet/length)
    I also think if the same unit that makes the waypoint goes back to it your accuracy increases. (repeatability)

    I do. I went to the one wp with the HDS 7T. I was within 5' (I used a stump as a visual reference).

    It was windy as heck today and forecast tomorrow. I was gonna try and go out and verify my experiences so far with the Xi5. When did you get your unit?
