Jig Head Sink Rate

[brunsbreambo]

Hey guys, just wondering if anyone knew the approximate sink rate of different jig head weights. Recently I have been counting down blades and trying to the same with placcies though am unsure of the rate at which the lure is sinking. Mainly looking at weights ranging from 1/20 to 1/8. Please don't take a guess as I am looking for fairly accurate times as I find deepwater fishing calls for this sort of application.

how long is a peice of string.

The type of plastic will make a HUGE difference as to the sink rate.

I have done test in my swim tank and a flick stick with a 1/24 jig head will sink at the same rate as a whippy worm with a 1/12 jig head.

Bigger bulkier plastics will slow the sink rate of a plastic.

Current and tides will also effect a sink rate.

When i start a session ill find some water 2-3m deep. drop my plastic overboard and count how long it takes to sink to the bottom.

Divied by how many meters im fishing in, and this will give a round about estimate of sink time per meter

Thats a good idea. I guess I wasn't really taking into account current etc and yeah I get what your saying. I guess its alot easier with blades.

Nitro jigheads have a chart for sink rates on the back of the pack.
It's only a guide and depends on the type of plastic you're using of course.

Also bear in mind that the sink rate slows the deeper u go. Salinity has an effect albeit minor

Yep. forgot to add that. That happens due too more line in the water that acts like a parachute

Also water temp is a factor, water is at its most dense at about 4 degrees. Plus the sectional area of the river, a shallow narrow will have faster flow than a wide deep section on the same tide (volume of water movement). So basically what mad eye said its a bit of string lol.

Oli,

Here are the sink rates as per the NITRO PACK,
1/32 - 13cm per second
1/24 - 18cm " "
1/16 - 23cm " "
1/12 - 26cm " "
1/11 - 28cm " "
1/8 - 30cm " "
1/6 - 43cm " "
1/4 - 53cm " "

As has already been said mate there are a few factors that will change this as well.
Regards,
Norto.

Yep Parachute effect and water pressure increases as well

Are you sure that's not inches per second mate? Not saying that your wrong with what it says on the back of the pack It just seems way too slow of a sink rate that's all.
I use 1/8 heads with Barkley craws and squidgy lobbys in 30ft of water and they are on the bottom in under 10 secs. It's not fast flowing water or anything.
In any case it's all dependent on numerous things it's more of an experiment and see type of thing

Norto has those sink rates right, according to the pack.

In deep water the density of the braid becomes more of an issue. Most are 0.96-0.98 which means it floats normally so chuck in the other factors that the guys have put up and it's a dynamic situation rather than one that you can precisely work out once and it will stay like that every time. I bought some sinking egi braid to help get them down and it does seem to help. But i also move up in weight for the jighead.
