Marking GPS points
« on: May 26, 2011, 08:41:29 AM »
I just have a quick question....i just installed my new 798si on my boat.  I took it out last weekend and started finding stuff i never knew existed.  i have my si set to 50' to each side, and I had my locator on the screen that shows the di and the si (the combo screen) and i drove by a brush pile that i wanted to mark.  When it showed up on my si screen ( 28' to the right) i arrowed over to it and marked it.  the only problem is that it does not mark it right, as the boat continues to move, so the the gps point until i finally am able to arrow over to it and hit mark?  is this because i can only be in the si screen only in order to mark a point?? 

any tips would be great

Thanks

Hey Green_o17,
A fellow Wisconsinite and also new owner of a HB SI (I bought an 898). I have also recently installed my unit on my boat and am anxious to hear what other members say about marking points in SI mode. Thanks for initiating the question!

On any screen, you can press the large 4 position control to freeze the screen.
Then, you can place your cursor on whatever you want to waypoint and press mark.
I think the screens capture all gps data on them in memory, so it doesn't matter if the boat has moved far, far away from the object when you press mark.

It still should mark it correctly.

I would also make sure that you are marking the brush at the location that it connects with the bottom of the lake.

Is this a 798 unit with an external GPS Receiver?  If so, where is the GPS Receiver mounted?

As we have seen in other posts, GPS position is determined by the GPS puck so it is important on longer boats to have the puck and the transducer close to each other.
The good part of sonar is you can have a gps position to go to and while the accuracy may be off a few feet you get close and then your sonar will show the target.
For example, if you navigate to within 15 feet of the target .....an si scan set to a range of 20 feet or 30 or....... will display it on the screen.
Hey...this is what sonar is all about...
