Sold / Closed DOWN RIGGER CABLE LEVEL ANGLE FINDER

[ted]

DOES ANYONE HAVE OR KNOW WHERE TO FIND THE OLD TYPE CANNON BALL DEPTH FINDER? ITS A LEVEL THAT MEASURES THE ANGLE OF THE DOWNRIGGER CABLE WITH A CHART ON THE BACK THATGIVES YOU THE DEPTH OF THE BALL AT THAT ANGLE.IF ANYONE OUT THERE KNOWS WHERE TO FIND ONE OR HAS ONE I AM INTERESTED.CALL ME AT 570 3597699. THANKS TED

I don’t have the device to measure the angle, but have this data sheet. I think it’s the back you mentioned.

Is that data sheet based on a certain cannon ball weight ?

[lost a lure]

That is based on trigonometry!

[joelagreca]

commen core math would have it up side down!!!!!!!!!

It would not matter if the ball was 1 lb or 100 lbs the chart would still work. It's the angle of the cable that matters not the weight of the ball. 

[Bozeman Bob]

Wouldn't the cable have a tendency to bow and do underwater currents affect the degrees in any way. The cable bowing would be my biggest concern. Seems to me that the angle at the boom may be less than what it might be in the middle of the cable. Has anyone taken a angle finder ,used the degree found and compared it to say a Fishhawk probe to verify the theory with all the possible variables ? Sorry, anything other than basic math was not my strong suit when being schooled.

I think it’s more a guideline to get you close. Like a dipsy chart... If I can get a protractor mounted on my rigger boom, I’ll check the chart against my FishHawk. Someone remind me when the season hits!!! Lol!!!

still looking for the tool [level] itself.

Whats the point use your sonar to track your down rigger ball.

[ted]

the angle of the cable gives you the depth of the ball not how many feet to the ball.when trolling the faster you troll the higher your ball rises due to blow back.the level reads the angle match it up with the chart with how much cable is out & thats the depth of the ball

[Fishnut]

Whats the point use your sonar to track your down rigger ball.

Tracking the depth of your balls with your sonar will give you a false reading. Because your ball might be 60 feet from your transducer but it’s blown back 20 feet behind the boat. So the distance to the ball from the transducer is 60 feet but the actual depth of the ball is a lot less. It is somewhere in the 50 to 55 foot range.

You have the chart above. Easy to make one. Square pc. of wood with a protractor attached. Put a pendulum at the top. Align the edge of the wood with the cable and the pendulum will give you the angle.

fish usa  has them in the boat electronics section

I saw something like that at cabelas but thought the one I saw measured speed based on the cable angle.

Your sonar (distance finder) will show the distance your weight is from the transducer. It does not mean you are trolling at that depth

Hey guys the tool i am looking for is square piece of wood or plastic with a bubble level on it that measures in degrees therefore gives you the angle of the downgigger cable.It comes with a chart like the one above so you can match the angle of the cable with the amount of cable out .this measurment gives your actual depth of the cannon ball.Thanks everyone for responding.

I made up charts years ago that I used with a simple protractor from the store. This was before I got a probe that shows actual depth. It’s a real eye opener to see how much cable you need to deploy to reach a specified depth. I now use 16 # torpedoes. MUCH less blowback as son as I can dig out my tackle bag I will take pics and post them. Hope it will help 

[Fishstix]

I always figured if you have to go down 50 they can come up 10.

 

Seen one years ago ,I think it was at Ekerts in Ithaca.I know this post is no help.

chinook 35 how did you measure the angle of the cable with the protractor. what acted as the pendululm.or level do you have a pictuer of it?.thanks ted

[chinook35]

I used the arm of the rigger to get a rough level. A bubble level would be useless on a rolling pitching boat. The angle is close with this method. Not perfect  

[srd]

I attached the protractor to the square pc. of wood and used a cotter pin as the pendulum. Align the left or right edge of wood with the cable and pendulum will tell you the angle
