    *I always record on the HB unit in 800kHz to get the best detail for the recording and then use the tools in Humviewer to adjust the Contrast and brightness of the recording...
    *I use the 4pane view with DI over 2d on the left....and SI over track on the right...(the track pane helps me visualize where my boat was at any point in the recording I'm viewing)..
    *Sonar frequency (2d/DI/SI)...is dictated by what frequency the recording was made...
    *I adjust the 2d and DI pane "Crop to" setting to the next depth choice deeper than the water the recording was made in...
    *I choose the Palette color that shows the best for the particular Enviromental conditions the recording was made in...(hard bottom I will choose Blue or Amber - soft bottom I will choose Green)...
    *Playback Speed depends on if I'm looking for 1 specific item (faster)....or if I'm studying and marking waypoints (slower)...
    *I always name waypoints in Humviewer with the identifier the HB unit put on the Recording...R000x...(x is the sequential recording ever made on that unit)..then I add an additional "b" for brush .... "sb" for stakebed...."st" for stump...then I also add a sequential number such as 1, 2, 3, ect to indicate the waypoint in that specific recorded track...so the 1st waypoint marked in that Humviewer recording may look like "R0009br1...the 2nd waypoint marked in that Humviewer recording may look like "R0009sb2...etc
    (Note: when these waypoints are run thru HBPC and loaded back into my unit...I know those waypoints labeled with the "R0000x" prefix were created in Humviewer)...(so anytime I'm on the water and I'm close to a waypoint named with the "R0000x" prefix, I will go verify that waypoint to see if what I marked in Humviewer is actually something worth keeping in my HB unit waypoint memory...if it turns out to be nothing, I delete it from my HB unit memory)...

    Wow didn't know about all that ...Thanks..... what about sens and contrast.

    I use the sensitivity setting (Humviewer and in the HB unit) as a brightness controll dictated by bottom composition...

    A mud bottom will not reflect much sonar so a higher sensitivity setting is needed...
    A hard rock or gravel bottom will reflect a lot of sonar so a lower sensitivity setting is needed...

    I only change Contrast if I want the fish to stand out more against the bottom detail...because more Contrast makes the image "grainy" looking...

    Don't know for sure, but I would vote for fish. The shadows to the left are elongated because the bottom is sloping away from the boat.
