Thread: 798 hd si

it is not a sim card it is a SD card, Gps maps are on it,if you get the fishing maps they are on there on one, the other use is for storing extra data and i use mine mostly to upgrade the software, right out of the box it will probably have an upgrade available.

The side imaging was blocked by the pontoons.

I was curios about this. I fish a pontoon also. Where do you have your puck mounted? Does the lower unit interfere withthe signal if mounted on end of pontoon? anything else i should know

If your pontoon has a spot to mount it low and at rear it will work good on one side restricted on the engine side unless you have trim and or tilt, i had mine mounted in front of the motor in the center and it was in line and blocked by the pontoons.

Got it mounted we are going to try to go tomorrow and try it out

If you are barely moving you get a doughnut instead of the boat icon(and directional indicator) on the GPS. I'm no expert but this seems to make sense to me. Without sufficient speed there is no way to determine which direction you're moving in. It can be frustrating when you're within a few feet of a waypoint(say a brushpile) but not directly over it. In open water I have trouble getting right on top of them especially when it's windy. Shouldn't matter as much when you're trolling but when vertical jigging tight to cover it matters a lot.

I get the doughnut when under .5 mph or just drifting, if I'm not on a direct line. If I'm trolling a more or less straight line even at very slow speeds the directional indicator shows up.

A tip locate the brus pile/structure at what ever speed works and toss a marker, then anchor over or near the marker. works for me.
