Not unless it can flow Upstream lol

Has anyone been to Altmar ? I wonder how the salmon run is progressing Hearing conflicting reports. Lots of salmon or few salmon. Both can't be right. Sent from my iPhone using Lake Ontario United

Pancake weights = tangles PERIOD I have 2 13 # weights that live in my cellar and will never see the lake again . The large surface area cause cross currents to give pancakes a life of their own . Save yourself a lot of grief and invest in shark/torpedo weights .

Slimy , oily things .

Great eating whitefish used to be a delicacy when they were plentiful . They fish for them in the adirondacks (Piseco Lake) with clorox bottle bouys .

I really need to invest in shark/torpedo weights . I have so many finned balls in 10 , 12 and 15 lb and some 13 lb pancakes ( tangles on tangles in a cross current , I retired those and they sit in my cellar collecting dust ) ,that I just can't justify the expense . Next year ,for sure .

The amount of rigger cable you need to reach a certain depth is affected by down currents , boat speed , amount of drag from lures you are using , weight of cannonball , on and on . LOL . 130 ft of cable is a good starting point to reach 100 ft fishing depth . Watch your rigger cables and try to estimate the angle from vertical . The bigger the angle ,the more cable you need out . I was out Thurs. and going with the waves I needed 140 ft of cable out to reach an actual ( speed n temp ) depth of 103 ft . using a finned 15 lb cannonball .

Yes. Your boat is traveling over the fish ( hopefully). That is why they appear as arches. As they come into ur ducer cone the sonar sees them as farther away as you move directly over the fish ( the top of the arch is the real depth of the fish ) the arch starts back down as you move away. They are separate entities as is the bottom of the lake. Ur rigger balls are traveling along with u and are returning a constant signal from a set distance Sent from my iPhone using Lake Ontario United

I belive the cone angle on an 83 kzh ducer is 60 Degrees . And if my information is valid (been looking at Lowrance CHIRP 7 ) an 83 kzh ducer covers an area roughly equivalent to water depth ie : 50 fow = 50 ft diameter circle at the bottom . Again your sonar is a DISTANCE finder . It will return an echo from an object X number of feet from the transducer . if the bottom is 100 ft away from the ducer the ping is returned and your unit shows bottom at 100 ft . You let out 100 ft of rigger cable with your ball attached , the sonar ping is returned from an object 100 ft from the ducer . Is it at 100 foot depth ? Absoluetly not , unless you are drifting with little wind and your cable is straight down . With a 30 degree cable blowback ( not unrealistic at 2.5 mph , an 11 " flasher and meat rig, perhaps your down temp probe , and loading the rod ) you are going to be fishing well above 100ft . But your distance finder is going to show that you are fishing at 100 ft . And CopperJon , you are absoluetly right about the x4D That is why I went for and still have the Speed n temp shows actual fishing depth no guess work

When my speed n temp finally sends its last depth and speed and temp. I will be buying an X4D. Sent from my iPhone using Lake Ontario United

Lol. I feel your pain. I felt the same way trying to get my mind around this Thing I started out with simple geometry to figure out cable blow back angles and calculating amount of cable to let out to reach a depth I still have tables I made up for angles from 10 to 45 degrees. The speed n temp took the guesswork out of it I guess my intention was to convince rollmops that he was not trolling at the depth he thought he was Hope I got my point across I should seriously consider investing in sharks they seem to have a lot less blow back. But even they will change from day to day. And even hour to hour depending on speed and down currents Sent from my iPhone using Lake Ontario United

Think about this for a second . It took me a long time and a lot of pros telling me ,before I got the picture . I don't mean to lecture .but just take a look at what you said . I use a 200/50 Hz transducer ,which clearly shows my cannonballs and any thermocline . Quality is not an issue . The thermocline is at say 100 ft . , It is not altered by the speed of your troll or cable blow back . Now , you let out 100ft of cable . Your transducer/sonar is showing that your cannonball is 100 ft from the transducer , it also shows the thermocline at 100 ft . It does NOT mean that your trolling at 100 ft depth . It is showing two things 100 feet from the transducer . The sonar will show both objects at 100 ft They are NOT neccesarily at the same depth

I can understand what you're saying , BUT , your fishfinder /sonar is NOT showing the depth of your cannonballs . It is showing the DISTANCE that your cannonballs are from the treansducer . The counter on your rigger should read the same as the distance showing on your sonar . It took me a long tome to get this truth through my head . I use 12 and 15 lb finned balls and find tha it is neccesary to let out a lot more cable than I would have imagined . I bought protractors to measure cable angle and figured out angle to cable length . I find that to fish ,say 100 ft down , it needs 150 ft of cable out . trolling speed and down currents can alter this . I use a Cannon Speed and temp now and it verifies my findings . it sometimes takes 180 ft of cable to reach 100 ft .

Reading your post I am thinking . When you say you were fishing 120 ft down over 140 fow . Did you have 120 ft of downrigger cable out ? or a probe telling you that you were fishing at 120 ft ? With 120 ft of cable out and depending on your speed , you would actually be fishing at approx. 80 ft . That could account for the browns .
