Plumbing and finding the depth of the lake, canal or river when pole fishing is a lot easier than finding the depth when you're float fishing because you can simply lower the plummet into your swim and gently drop it onto various areas of the swim to gain a true picture of the venue's depth.
It's a vital part to a successful session as it will give you a true picture of what's under the water and therefore give you a great insight into where you should be feeding and placing your bait.
You can also use your plummet to locate any underwater obstacles too by gently 'swinging' the plummet through the swim to see if it becomes lodged against anything that's submerged.
Here's how to go about finding the depth on your pole line...
Pass your hook through the eye in the plummet
Secure your hook into the cork in the base of the plummet.
Lower the plummet into the swim below the end of your pole.
Add a section of pole at a time and plumb around the swim, lowering the plummet straight down, not at an angle, to ensure an accurate reading of the swim.
Once you have got the exact depth of the swim, hook your hook into the base of your pole top kit. This will pull the elastic out slightly and secure your rig. With Tipp-Ex, mark the point where the top and the bottom of your float sit against the pole. This means you always have a point to refer back to should you change the depth you are fishing during the day.
A. This shows the float is set too shallow
B. This shows the float is set too deep
C. This shows the float is set perfect
