Help! xi5 , HDS , point 1 antenna

Hi! I am looking for some guidance.

I have a Lowe SF212 walk-thru 22ish foot pontoon. Transducer back left. Xi5 up front(2D transducer that I use when deployed). Lowrance HDS carbon at the console. I just purchased a point 1. Tired of the graph spinning while sitting still.

Where should I mount it, and why? Should I use it for GPS or only heading? If I mount it in the back by the transducer and us it for GPS, I will be 22 foot from my waypoints, correct? I fish off the front of the boat.

In my mind I need the GPS as close to where I fish as possible. What am I missing?

Thanks for the help.

Waypoints are marked at the GPS antenna position ...

Therefore, the GPS antenna should be as close as possible to the transducer that you are using to find the structure ...

Rickie, thanks for the reply.

So let’s say I’m cruising along, mark a spot 100 foot to the left using sidescan. I circle around, deploy the trolling motor, anchor over the waypoint. The spot I marked is now under the GPS antenna. If my puck is at the back of pontoon, and I’m fishing out of the front, I’m 22 foot away, correct?

I use use the back transducer to find structure, but fish out of the front of the boat, using the transducer on the trolling motor while deployed.

You are correct ... when returning to marked structure - the GPS antenna is “Trying” to get to the same coordinates on the Earth that were assigned at the original marking ...

A better scenario would be to have a GPS antenna at the rear xducer for marking waypoints while using the console unit ... (the rear GPS antenna would not have to be a Point 1 because idling with the big motor is moving the boat fast enough for stable GPS function) ...

And then have a Point 1 at the front for returning to waypoints (and keep Chart from spinning at slower speed) ...

Thanks Rickie
