As a rule with sonar, the lower the frequency goes, the further the sound will travel. The higher the frequency, the greater the resolution. Sound in the audible range is used to find big object like submarines miles away, but a very high frequency is used to see the precious baby in a mother's womb.

Even with that knowledge, I have been too lazy or preoccupied trying to catch fish to figure out how to make changes like that on my Lawrence. Dropping to a lower freq will extend the range, but it is still a high enough freq to get pretty good detail.

Thanks!

Ya you're totally right... the downscan frequencies (455/800) give even greater detail. But they can see such small objects that the scattering layer can be too much for them too look through. On 83 (or med chirp) small objects will kinda all lump together as big clouds, where as on 200 or hi chirp
you might see individual sardines. If you can run dual frequency there are a lot of advantages and further inferences you can make... but that will have to wait for the intermediate lesson.

Another thing to remember is the scale of column. When fishing in deep water say over 150', the returns look so much smaller due to the scale of the fish in relation to the depth of the water. A school of yt in 200' looks almost identical to a wad of greenback in 65'.

If you're preoccupied with catching fish... tuning your sonar is how its done.

i have been "trying" to catch fish instead of learning to catch fish. BWE is helping me to overcome that. When I caught a BSB a few months ago, i was using a mackerel bigger than I had ever used before, and it worked! I almost didn't use it because I thought it was too big, but I dropped it down to soak while I fished another pole with plastic. "Big bait = big fish". I am now a believer.

YT also will take very large baits... and usually prefer them. I'm sure many will attest to that hahaha

Nice! Ended up watching some of your other YT vids. Cool stuff.
