Thread: ping speed setting question

This is from another forum and for a Lowrance 520C.

put your unit in shallow water mode

1. ping speed 75
2. noise reduction low
3. surface clutter low
4. color line 72-74
5. chart speed 100
6. sensitivity- console run on auto, but if you like run on manual, try 72-78 %

Ping rate is determined by the acoustic signal real time (distant) to underwater target. Deeper water requires more time to target while shallow water requires less time.

If you have 2 sonars operating at the same transmit frequency, you can change the ping rates so to offset same signal interference.

I meant to also stated that it ain't this simple. I am having the "darvon effect", which is similar to the Doppler effect.

so shallow water slower ping speed/rate is good?? and deeper water faster/higher rate will be better?? also its a feature to where you can set 2 diff finders at diff speeds to keep them from goofing each other up???

I am running an eagle fish elite 480 so there is no color setting, but the other settings you have lister are how mine are set, other than I have the ping speed at 100 %.

this unit I have now will be moved to the trolling motor next spring and a better color/gps unit will be put in its place. been reading up as much as I can on finders and trying to educate myself on it all before I go plop down 600, 700, or more even if I can save enough for SI or xd unit.....thanks for the input canepole & stevej......have a great one all, God bless...

shallow faster. deeper slower.

yes, changing ping rates can stop same frequency interference.
