Sinkers and leads
Tackle · Last reviewed 2026-08-10
The weight that puts a bait where the fish are and holds it there — chosen for the current rather than the depth, and changed through a tide rather than once.
Safety
Lead and toxic materials — Can cause injury needing treatment
Lead is toxic by ingestion and is handled repeatedly, frequently alongside eating and drinking on a beach or a boat. Sea angling also loses substantial weight to the seabed permanently, which is an environmental question distinct from the personal one.
What reduces it: Wash hands before eating or smoking, and never hold sinkers in the mouth. Keep them away from children. Retrieve tackle where it is safe to do so, use rigs that reduce loss over rough ground, and use non-lead alternatives where they are available, effective and required.
Line under tension — Can cause serious injury or death
A heavy sinker released suddenly from a snag, or a crack-off on the cast, becomes a projectile travelling at speed towards whatever is behind the angler. Beach casting weights in particular carry enough energy to cause serious injury.
What reduces it: Check behind and beside you before every cast. Use a shock leader matched to the weight being cast — this is not optional at beach-casting weights and it is the single measure that prevents crack-offs. Never pull for a break with the rod pointed at anybody, including yourself, and wear eye protection.
Precautions that always apply here
- Check the tide before you go and know your exit route. Being cut off is the commonest way a shore session becomes a rescue.
- If a hook goes past the barb into a person, cut the line, leave the hook where it is, and get medical help. Pulling it back out does far more damage than pushing it through under proper care.
A sinker does one job and the job is harder than it looks. It has to take the bait down through moving water, hold it in position against a current that changes strength continuously through the tide, and do both while remaining light enough that a bite can be seen and the tackle can be cast.
The governing principle is one line: USE THE LIGHTEST WEIGHT THAT HOLDS. Every gram beyond that costs bite detection, casting distance and the naturalness of the presentation, and a great deal of sea fishing is done with far more weight than the conditions require.
Shape does more work than most people expect. A PLAIN or BOMB shape rolls with the tide and searches ground, which is useful over clean sand and a nuisance over rough. A GRIPPER carries wire spikes that dig in and hold against strong flow, and versions exist where the wires release under a firm pull so the tackle can be retrieved. A FLAT or WATCH shape resists rolling without gripping. A PYRAMID digs into soft sand as it is dragged. Each is right in its conditions and wrong outside them.
And the material question is live. Lead is dense, cheap and easy to work, and it is also toxic, restricted in various jurisdictions for various uses, and lost to the seabed in substantial quantities. Tungsten is denser and much more expensive; steel and stone are cheaper and bulkier. What is permitted differs by place and by fishery, which is a matter for local rules rather than for a general reference.

- Weights
What it does
Provides the mass to cast the tackle, to take it down through the water column, and to hold it in position against tidal flow. Shape determines whether it holds, rolls or digs in, and the balance between holding and being detectable is the whole design problem.
How to choose one
- Use the LIGHTEST weight that holds position, and change it as the tide builds and drops away rather than choosing once.
- Plain shapes to roll and search clean ground; grippers to hold in strong flow; flat shapes to resist rolling without digging in.
- Over rough ground, use a rig that sacrifices the sinker rather than the whole trace when it snags.
- Release-wire grippers give the holding of a gripper and the retrievability of a plain lead, at the cost of complexity.
- Check what is permitted locally on materials before assuming lead is available for the fishing you intend.
What the numbers mean
WEIGHT is quoted in ounces in Britain, America and much of the Commonwealth and in grams across most of Europe, and rod ratings follow the same split — a rod rated 4 to 6 oz and one rated 100 to 175 g are describing the same thing. SHAPE names — bomb, pyramid, watch, gripper, breakaway, torpedo — describe holding behaviour rather than size. WIRE GRADE on a gripper determines how hard it holds and how hard it is to retrieve. MATERIAL: lead, tungsten, steel, brass or stone, differing in density, cost and what is permitted where you are.
Care, and how it fails
Sinkers themselves rarely fail; the connections to them do. Check swivels, links and the loop the sinker hangs on, since these corrode and are the actual failure point. Grippers bend their wires and lose grip gradually — reshape or replace rather than persisting. And the practical failure is a box of leads chosen last season for a different tide: carry a range wide enough to change through a session, because the correct weight at the start of a flood is the wrong one two hours later.
What this is called elsewhere
FishingHQ’s headword is the term used in Britain & Ireland, Northern Europe, Western Europe.
- Sinker — North America, Australia, New Zealand, East & Southern Africa, Global
- The standard term almost everywhere outside Britain and Ireland, and the more literal one — the object's job is to sink.
- Lead — Britain & Ireland
- British usage names the object after the material, which has become awkward as non-lead alternatives have spread. A tungsten lead is a normal phrase in Britain and reads as nonsense elsewhere.

Understanding it
- Grip leads, plain leads and holding bottomThe tackle record lists the shapes. This is where the reason a lighter gripped lead holds ground that rolls a much heavier plain one is set out, which is the fact the shapes exist because of.
- How sea tackle differs from freshwater tackleLeads measured in hundreds of grams rather than in grams are the most visible consequence of depth and current, and they set the rod and reel around them.
- How weights and sinkers workCasting, sinking and holding are three different jobs asking for three different shapes, and a tackle box organised by weight alone hides that.
- Presenting bait in strong tideGrip and plain leads are two answers to the same problem, and which is right depends on the ground and on whether the bait is meant to stay or to search.
- Weights and sinkers: converting ounces, grams and swan shotOunces and grams convert exactly and the traditional shot sizes do not, which is why this is a page rather than a calculator field.

Check the rules before you fish
Fishing laws, bylaws, access rules, seasons, bait restrictions and permitted methods vary by location and can change. Check the current rules from the relevant authority and the water you intend to fish before fishing.
Check with:
- Current national or regional law for where you are fishing
- Current local bylaws
- The relevant fisheries authority
- The landowner, club or fishery whose water it is
- Any restrictions specific to the species or the method you intend to use
