Scotty Hp downriggers

I have been having issues with my scotty HP's not counting accurately, I even talked with Craig from scotty at the boat show and he sent me some new counters,
well that didnt fix it and I called him back and he said try stipping a 100' off, still was out so tonight I started stripping more cable and found that once I had only 200' of cable on the spool they read correctly
so any opinions on minimum cable lengths, should I cut it off at 200 and know how much is out or leave more and and not really know whats out unless I want to do some math everytime I drop the balls,
with the 400' I have on there now when I drop a 100 it reads 86ish feet
opinion anyone

I'm guessing here but line diameter is the variable here. Thicker diameter means diameter on DR is more. Find diameter of line they are using and get smaller or braid. Of course, then you will probably get a wrong reading at shallower depths. Then you have differing amounts of blowback. So until someone comes out with a small device that attaches to your weight, like an altimeter, that measures depth, depths are relevant. There are a lot of things you can do to tweak it but is it worth the time.
 
I'm running the HP's also. I have noticed that it seems they may be out to lunch on depth.
What I do, when fishing deep, is I touch bottom then bring the DR up 5 to 10 feet.
If fishing in the top 100 feet of water I don't think it matters if it's out a few feet.
Only way to confirm is to take a tape measure and measure out 100 feet and test DR on land.
I'm still using the braid that came with the DR and think it's the 250# stuff.

b55 is sort of on track here but it's more to do with spool/drum diameter and the gearing on the counter.

As you pay out line the circumference of the line pile decreases and with that, length of line payout per revolution decreases while the gearing counting the revs for the counter remains constant.

No way to avoid this; it's physics.

All you need to do is know what's happening.

Try this: next time you are out on a high/low slack, find a level sand/gravel bottom (assuming your sounder is accurate) at exactly 100'. Lower your ball till it stops. Note the deviation, if any.

Now move to say 200' depth and repeat the procedure and again note the deviation if there is any.

Now you have a choice to either remember that you are going to be say 20% deeper (actual) when the display says 100/ft and that you are bang-on @ 200', or, if this is not satisfactory you can remove 'X' amount of line from your unit till you have the right circumference of line loaded so that your unit will read bang-on at the most common depth you fish at.

Hope this helps.

I am curios are you using steel or braid. Does that make a difference?

If using different types of braid or steel with different diameter than what Scotty used for calibration it would also probably, make a difference.

There is certain logic that Scotty would have calibrated the new counters to one line type and a specific amount of line out and amount of line on the rigger. One assumes they would have tried to hit a good average for what they thought the majority of anglers would be using.

The farther you get away from what the parameters were when they did the calibration, the less accurate will be the read out.
If the spool diameter and width on the high speed riggers is the same as the normal speed riggers they may just have calibrated the new counters to read the same as the old manual counters which also would be less accurate the farther you get away from the parameters used for calibration. Over time we seem to be putting more cable on our riggers and it may be that originally the counters were calibrated for something like 200 feet of steel cable.

You are implying that the new high speed riggers may be less accurate than the old style riggers, if so that would suggest that they did recalibrate the new counters assuming other factors with the riggers are the same.

There are so many factors that effect what depth you are actually fishing from the depth on the counter including boat speed, current speed and direction of boat relative to current, weight and type of ball (pancake or ball, pancake with curved blade to steer the ball away from the boat – more drag lifts the weight) and braid or steel and anything else that effects drag and blowback including having a fair bit of weed on the cable.

If I am fishing Chinook in a place like Sooke I am usually more concerned about where my lure/bait is in the water column not how much cable I have out and trying to match my place in the water column with what I know about where the Chinook are (fish arch on sounder) or likely to be (winter Chinook just off the bottom) or where I was in the water column and the perimeters at the time I just caught the 30lber so I can get back to the correct actual depth fast not just the location on the chart plotter I want to be at.

In an area like Sooke (mostly safe bottom) and not on top of a rock reef I will sometimes put myself more accurately where I want to be in the water column by putting my finger on the up button, dropping the ball at speed until it hits bottom and then bring it up a couple of feet, wait for drag to raise the ball and set the angle of the rigger cable then hit bottom again and adjust upward that way I know I am say 20 feet off the bottom, not a bad place to be for large summer Chinook much of the time unless you are in very deep water or about to be going over a reef with a rapid depth change. But nothing stays constant, if you change directions, if the current slows down, if the bottom is coming up, you adjust.

I think the reason the best guides are so successful is that they have decades of experience with their gear and knowledge of local conditions and the various runs of Chinook coming through and their brains do these kinds of calculations and keep track of a thousand other variables automatically. To the rest of us and especially beginners, it just seems like magic.

I use on of those Hand Wheels with the counters... you can even rent them...for messuring landscape jobs...Or road crew uses them all the time for marking lines etc..
I had bought a big spool of used prawn line from a commerical fisher... said it was 1,000ft.. so I bucked it in half and thought I had 2 nice 500' lines... Negative.... they were way short, just cant believed he lied to me...lol..

Anyways those wheels are accurate and fast...
 
I am using the exact same HP stainless they came with, I understand all the different parameters that come into play,
just seems strange they are only accurate with 200' of wire on them when they actually ship with 300'
I had braid but had issues snapping ballls, autostops sliding around and clips not staying put so I went back to the 180lb HP wire
I have measured them off on land and at 100' on the counter there is 86' of cable out

As I was trying to say, if Scotty just used the same calibration on the new counters that they developed for the old manual counters back when their downriggers typically came with 200 feet of steel cable it is not surprising that they are most accurate with 200 feet of steel cable on the rigger.

Thanks and that explains why in the past (old DR's) I fished at 180 feet and now I mostly fish at 220.
Scotty must have been a sleep when he calibrated these new DR's

If you have the stock setup with300' of line then at 220 you will actually have 206' of wire out subtract 14 from the first 100 then its normal after that
 
Ok so here's what I did today,
first I stripped off the remainder of the scotty HP stainless cable, then I started to load on 450' of powerpro 200lb which is equal to 50lb diameter
I measure out 100 feet of braid set counter to zero walked out the 100' and had my wife hit the switch for me, I did this so I could wind it on tightly and make
sure that I was holding it tightly so that no more could sppol off the roll, once I hit my 100' mark we stopped the rigger and checked the counter,
-108' Hmm thats alot better and more liveable then -86', ok so mark off the next 100' and start again, zero counter and hit button -103' on the second pass, getting better,
ok onto the next 100, reset counter and go 98' this time, much better, 4th pass 99' almost perfect and last 50' was 49'

so on a 450' spool of powerpro 200lb if my math is right its only out by 7' total and I dont think you can do any better then that. and really your only going to use that last 250 at most
so your actually within 4' of accuracy.
I am happy with that and hopefully this will help someone else too

Nice work.. :)
 
Hey Deryk,
Thanks for the input and help
good call on the powerpro

I've been using Powerpro 200 for about 5 years now, not sure about the new hp riggers, but it's accurate to the foot
on my old Scotties.
 
Even though you are calibrated on the rigger, any deeper than 50ft and you have to start to consider the parabolic arc of your downrigger line. When trolling at 2.5kn in 180ft of water, I've let out as much as 250ft of cable/braid (calibrated old scotty) before reaching bottom. Unless you can sound your ball, it would take a mathematical genius to equate exactly where your ball is, given forward momentum, drag, and the angle/arc of the cable. Its nerve racking trying to find bottom when under power but it's something that, just like pulling your e-brake on the car, you need to know.

So when Im fishing in 150+ feet of water, i typically go plus 20-25' on the rigger, so 150 deep, 175 on the rigger (that's if I am working the bottom.) if deeper than 200 I judge the speed/angle of the cable and will likely add up to 40ft.

This is just how I do it. 180' deep is never 180' on the rigger to bottom, when trolling. Be warned though, reducing your speed will drop that ball down quickly and you may bottom out if you have compensated for your usual trolling speed.
 
Fb I can see my balls on my HDS10 and its alot closer then that even when the counters were out on the scotty's, i think you need some bigger balls man;)

I've wondered about Scotty's counting method ever since I used the small, manual, Blue downriggers back in the '70s. Scotty hasn't changed their counting method in over 40 years (gawd I'm old).

Too bad they haven't changed to actually measure the line coming off the drum, similiar to those commercial spooling devices the shops use for putting line on our reels. This way, as the line goes out, it will actually be measured (not measuring the revolutions of the downrigger drum).

Hey, maybe I'll mention this to Craig when he comes up to the Harbour Chandler Pirate Day sale tomorrow.

Craig and I have discussed that method already, and he did have a reason for not doung it that way but I dont remeber why, but when your talking to him let him know that a 450' spool of powerpro 200 solved my issue
