Sonar pinging question

[bigmojet]

If i am running my Humminbird 788/798 in just GPS view, is the unit still pinging the bottom even though sonar is not shown on screen?

Just because you are on a gps view screen doesn't mean the sonar is not pinging.  You have to make sure the sonar is disabled.  Not sure how to do that part on the bird.

Set the Sonar Menu to "Off"...This will turn off both the 2D sonar and the Side imaging....You can't run just the SI or Visa versa but you can run just the GPS functions...

Thanks guys!

I just did a little more checking on this...(I am a new HB owner myself). There is suppose to be a "shortcut" to shutting off the ping....It was part of an update...

Try hitting the Power/light button once and see if a screen comes up with a menu to "Shut ping/sonar off"....

You can still do it from the Menu but this would be a faster option if it works..

I will try tonight.

Alot of guys like to shut the Sonar off because sometimes it interferes with another unit on their boat...Some Anglers believe it can alarm fish in shallow water...

I actually think about that more than I should.  If its windy, the lake has alot of traffic, or if I'm fishing deep I dont worry about it.  If I am in a shallow calm area, its always in the back of my head.  That clicking is pretty loud.

Some believe that the fish can pick up the sound wave in their lateral line thus putting them off or on alert.

I have never even thought about that. But, they are very loud. I know when I look at maps on my units in the garage, you can really hear it. Good question. Will definitely remember that.
