Much kinder to fish and easier for unhooking! These are the first advantages that come to mind when discussions on single hooks arise. It’s been a debate that many lure anglers have had over the years.

But in this article, we won’t be discussing the pros and cons. We will be explaining how to choose the right inline single hook, how to fish inline single hooks effectively and how to choose the correct replacement hook sizes.

What kind of single hooks should I be using?

If you’re looking to replace the treble hooks on your hard lures. Then you will require an inline single hook like the one shown in the image below.


Inline single hooks are specially designed to replace treble hooks on lures. They come with an oversized eye for increased articulation and movement. This accommodates split rings perfectly. The hooks have an increased gape (the gap between the hook point and hook shank) which improves hook-up ratios and hook holds.

So what are the advantages of using inline single hooks?

Apart from being sticky, sharp and very strong. Single hooks have a few advantages over treble hooks, let’s have a look at some of the below:

Strong hook ups

When hooking into a fish with one single hook, all the pressure from the strike is exerted into one hook point. Providing better penetration and more confident hook hold.

Lure Longevity

Unlike treble hooks, the inline single hook point is facing out away from the lure. So when the lure is working in the water, the hook points do not interfere with the flank of the lure. Treble hook points, on the other hand, can become dull when they constantly make contact with the flank of the lure when being worked through the water. This also results in the body of the lure becoming worn down.

Less Noise

This goes hand in hand with our previous point. Treble hooks tend to come in contact more with the flanks of a lure than an inline single hook will. This increases the amount of noise the lure will make. This could be disadvantageous if you’re fishing for wary fish or even fishing in calm conditions.

Reduced Snagging

We all run into snagging the bottom with lures. However, using inline single hooks you have more chance of recovering a snagged lure. Working one hook point out of a snag is far easier than trying to work 2 or even 3 hook points out of a snag.

Striking With Single Hooks

When using treble hooks striking from various angles does not really affect your hook up ratio. You have the added advantage of 6 hook points. So the law of averages is greatly increased for one of those 6 hook points sticking.

However, when fishing inline single hooks. The law of physics slightly differs due to the added articulation and movement, thanks to the oversized hook eye and the lure’s split ring. Striking to the side will see the hook have to turn to a degree before it makes enough contact to set a positive hook hold.

Once you have set the hooks from the side. The hook itself will then be sitting horizontally across the mouth of the fish. A few headshakes can see the hook work its way out easily.

To overcome this possibility. Strike vertically! This will ensure a more positive hook up and hook hold. Ensure you keep tension on your line at all times and keep the rod high. This will keep a better angle on the hook and keep the fish pinned better. Dropping the rod to the side to play fish will alter the angle the hook sits and may reduce the depth of hook hold.

Weight distribution

One thing to consider when changing out your treble hooks to singles on hard lures. Is the action of the lure. Depending on the action and weighting of the lure. This may be affected when changing the hooks. A lot of floating and suspending lure models are critically balanced and this is based on all weighting including the wire gauge of the hooks to the split rings used.

For the best results, weigh each hook and ensure the replacement hook is as close as possible to the original hook. If they’re not, experimenting with alternative split rings and hooks until you can near enough match the weighting to the original hook arrangement.

If we look at an example: The Megabass Vision 110 is an extremely well-balanced lure. So changing hooks or split rings will inevitably disrupt the behaviour of the lure in the water. Like we touched on earlier, if we removed the hardware of a suspending vision 110 and uprated the hooks and split rings, the chances are the suspending model would then start to sink.

TOP TIP: If you’re not confident with a 2 hook arrangement on a 3 hooked lure. You can opt to replace all three treble hooks with three inline singles. Ensure the inline hooks are small enough that they will never meet or cross with one another.


Step by Step To Replacing Your Treble Hooks With Single Hooks

Changing the hooks over is an easy and straightforward procedure. There are a couple of elements to take into consideration and we will be covering these below.

Finding the right hook placement is simple. You want to ensure you check a couple of things before replacing.

A general rule of thumb is to measure the distance from the hook point to hook point on the original treble hook. Then use the distance as a measure to compare the distance from the hook point of the inline single to the shank of the single. (See diagram)

hook measurement

Secondary, lay the inline single flat against the body of the lure. We want the hook point to be exposed and not masked by the wide-body profile of the lure. (See below diagram) If the hook point is not exposed enough, opt for a larger inline single hook on the belly hook hanger.
