Who it suits
Is it right for you?
Great for
- Slack-line anglers. The hanger can sit almost vertically and keeps the line low without a bulky, awkward arrangement.
- Delkim Plus users wanting a tidy illuminated setup. It plugs into the compatible alarm, adds illumination and gives you free-hanging or supported options.
Maybe skip if
- Anglers using alarms without a Delkim Plus NiteLite socket. The no-battery illumination relies on that compatible Delkim connection.
- Anyone wanting the simplest possible bobbin. The DuoCarb, D-Lok compatibility and optional D-Stak weights add flexibility, but also a bit more kit and faff.

Quick verdict
Verdict
The Delkim ES Indicator Set is a smart, refined bit of indicator kit for slack-line fishing. It hangs neatly, stays put on the line and gives you a choice of free-hanging or supported presentation.
It’s not the cheapest route into a bobbin-style setup, and you’ll need a compatible Delkim Plus alarm with a NiteLite socket. But if you already run Delkims, this is a cracking, low-faff upgrade.

Solid carbon, a tidy magnetic clip and a well-thought-out illuminated design give it a properly premium feel.
The flexible cable, adjustable clip and choice of mounting styles suit a broad range of slack-line presentations.
It won’t catch fish by itself, but a low, controlled line presentation can help you fish discreetly and spot movement cleanly.
It connects neatly, needs no batteries and releases smoothly, although compatibility and mounting options need understanding.
It offers plenty of refinement, but the premium setup is harder to justify if you don’t already own compatible Delkim alarms.

The full rundown
Everything you'll want to know about the Delkim ES Indicator Set
If you’re into keeping your line low, your gear tidy and your indication nice and clean, the Delkim ES Indicator Set is right up your street. It’s a two-part setup built around the ES NiteLite Pro hanger and the ES DuoCarb support. Proper neat stuff, without turning your front rest into a toolbox explosion.
The main job here is slack-line fishing. Rather than having a chunky bobbin pulling down hard on the line, the hanger can sit almost vertically and keep everything lying low. That’s handy when you’re fishing under your feet, across a quiet margin or anywhere you want to keep the line out of the way of wandering fish.
The ES NiteLite Pro is the bit that gives you the visual indication. It has an integral LED with flashing, latching and night-marking modes, so you can tune the look to the way you fish. A little light can be dead handy during a bite-time session, especially when the rods are set close together and you’re watching for that first twitch.
There’s no messing about with separate batteries either. The Pro connects to the NiteLite socket on a compatible Delkim Plus alarm. That keeps the hanger looking clean and means one less thing to remember when you’re packing the barrow. We’ve all had that cheeky forgotten battery moment, mate.
The 170 mm CatFlex cable assembly is designed to hang and flex like a chain. That gives the indicator a natural, flowing movement rather than making it look like a rigid arm bolted to the rod. It’s a small detail, but these are the bits that make an indicator feel properly refined rather than a bit naff.
The magnetic line clip is self-adjusting and non-twist, which is exactly what you want when you’re moving between swims or changing how tight you fish. It stays on the line until the strike, then releases smoothly. No wrestling with the clip and no big jolt as the hanger lets go.
You can run the NiteLite Pro free-hanging, or mount it to the ES DuoCarb. The DuoCarb’s fixed arm is 102 mm long and made from solid carbon fibre. It’s extra slim and feather light, so it adds support without making the whole arrangement look heavy. It connects to its supplied base or directly to a D-Lok, giving you a couple of tidy mounting routes.
There’s also room to tune the hanger if your swim or rig calls for it. The Pro is threaded for Delkim D-Stak add-on weights, letting you add weight when you need a little more control or tension. Those weights aren’t included, though, so factor that in if you’re building the full setup from scratch.
Colour choice is decent too, with blue, green, purple, red, white and yellow on offer. That’s not going to put fish in the net by itself, obviously, but matching your indicators to your existing Delkim gear is part of the fun. A tidy set of alarms and hangers just feels bob on when you’re settled in for a long night.
The big thing to remember is compatibility. This isn’t a universal illuminated hanger that works with any old alarm. Its battery-free operation depends on a Delkim Plus alarm with a NiteLite socket. If you’ve already got that setup, the ES Indicator Set is a very polished way to improve your slack-line presentation. If you haven’t, the value equation gets a bit harder to swallow.

Our take
The key angle
This set is all about keeping your line low and your indication tidy. The ES NiteLite Pro can hang almost vertically, while the slim solid-carbon DuoCarb support gives you a cleaner, more controlled arrangement when you don’t want the hanger swinging about.
That makes plenty of sense for slack-line work, especially when you’re fishing close in, keeping everything discreet or trying to avoid a heavy bobbin dragging the line out of position.
The setup
A neat two-piece indicator system
The ES NiteLite Pro is the illuminated hanger, with an integral LED offering flashing, latching and night-marking modes. Its 170 mm CatFlex cable hangs and flexes like a chain, while the self-adjusting magnetic clip stays on the line until a take and then releases smoothly.
The ES DuoCarb adds support when you want a more controlled presentation. Its 102 mm fixed arm is made from solid carbon fibre and is described as extra slim and feather light. Connect it to the supplied base or directly to a D-Lok, then choose whether to use the NiteLite Pro on the support or free-hanging.
Worth knowing. The hanger doesn’t use batteries. It connects to the NiteLite socket on a Delkim Plus alarm, so check your alarm setup before buying. The NiteLite Pro is also threaded for D-Stak add-on weights, but those are separate extras.
On the bank
Made for low, tidy presentations
This set makes the most sense for anglers fishing slack lines, especially when you want the line to sit low and the indicator to hang almost vertically. That could be a close-in margin spot, a quiet canal swim or a carp lake where you’re trying to keep the whole presentation discreet.
It’s also a good fit for Delkim users who like kit that works as one system. The illuminated hanger, compatible alarm connection and tidy support all pull in the same direction. You can keep things free-hanging for a relaxed chain-like movement, or use the DuoCarb when you want a more fixed and organised setup.
Match anglers and coarse anglers will appreciate the clean indication when fishing tight to features or using delicate slack-line tactics. It’s less compelling if you simply want a basic bobbin that clips on and gets forgotten. This is more about control, presentation and a bit of premium tackle pleasure.
Quick answers
The bits you’ll want clear
Does it work with every Delkim alarm? No. The battery-free NiteLite Pro is designed to connect to a Delkim Plus alarm’s NiteLite socket. That compatibility point is the first thing to check before parting with your quid.
Can you change the weight? Yes, the hanger is threaded for Delkim D-Stak add-on weights. That lets you tailor the feel for different lines, distances and conditions, but the weights aren’t included in the set.
What colours are available? You can choose from blue, green, purple, red, white and yellow. Handy if you want your setup to match your alarms or simply fancy a cheeky splash of colour on the bank.
