Product Details and Uses

Sonubaits Pro Groundbait – Thatchers Dark (900g)

The legendary Thatchers recipe just got a stealthy makeover. Following the massive success of the “natural” Thatchers Original, Thatchers Dark has been developed to give you the same high-performance attraction but with a discreet, low-visibility finish. This mix is the ultimate choice for the “thinking” angler who knows that on clear-water venues or during the colder months, a bright patch of groundbait can sometimes spook wary fish.

By darkening the original recipe, Sonubaits has created a mix that blends seamlessly into the lake or riverbed. It allows silverfish like roach, skimmers, and dace to feed confidently over the top of it without feeling exposed to predators. Whether you’re fishing the pole, a cage feeder, or a traditional waggler, Thatchers Dark provides a rich, fine-textured carpet of food that keeps fish rooting in your swim for hours.


Key Features & Benefits

  • The “Stealth” Factor: The deep, dark color is perfect for clear water conditions, preventing fish from “shying away” from a bright patch of bait.

  • Proven Heritage: Built on the original Thatchers recipe that has been a staple for the UK’s angling elite for years.

  • Fine Texture: Ideal for silverfish, creating a cloud of attraction and a fine carpet of feed without over-feeding the fish.

  • Highly Versatile: Works perfectly on its own or as a “darkening agent” to be mixed with other groundbaits to suit specific water conditions.

  • Consistent Breakdown: Designed to release attractors quickly, drawing fish into the swim from the first whistle.

How to Mix Thatchers Dark

For a perfect consistency every time, follow these steps:

  1. Empty the 900g bag into a round mixing bucket.

  2. Add Water: Fill a 1-pint maggot tub with water and pour it onto the groundbait.

  3. Mix & Rest: Mix thoroughly by hand (or whisk) and allow it to rest for 30 minutes. This is crucial as it allows the particles to fully absorb the moisture.

  4. The Secret Finish: For the best results, pass the rested groundbait through a riddle. This removes any lumps and creates that fluffy, even consistency that creates a perfect cloud under the water.

  5. Alternative: Many pros now prefer using a cordless drill and whisk for a faster, ultra-consistent mix.


Where to Use Thatchers Dark

  • Winter Silverfish Sessions: When the water goes tap-clear, the dark color provides a “safe” zone for roach and skimmers to settle over.

  • Clear Natural Rivers: Perfect for targeting dace and roach on the stick float or a small cage feeder.

  • Canal Fishing: Its fine texture won’t over-feed fish in the restricted area of a canal, while the dark color mimics the natural silty bottom.

  • Deep Reservoirs: Use it to create a subtle landing zone for Bream when the light levels are high.


Gerry’s Pro Tip

“At Gerry’s, we call this the ‘Confidence Mix.’ If you’re getting line bites but not proper wraps, your groundbait might be too bright and spooking the fish. Switching to Thatchers Dark often buys those extra bites. My top tip: if you’re fishing for big skimmers, try adding a handful of crushed hemp to the mix. The dark oil from the hemp matches the color perfectly and adds a massive scent boost that keeps those bigger fish cruising the bottom!”


Frequently Asked Questions

Q: Does the color wash out?

A: No. The dark color is part of the mix’s composition, meaning it stays dark even after being submerged for several hours, maintaining its stealthy properties throughout the session.

Q: Can I mix this with the Original Thatchers?

A: Absolutely! Many anglers mix them 50/50 in the autumn as the water begins to clear, giving you a ‘middle-ground’ color that works brilliantly as the seasons transition.

Q: Is it suitable for feeder fishing?

A: Yes, it is excellent in a cage feeder. It has just enough “stick” to get to the bottom but breaks down quickly to release its attraction.

Q: Will it stain my hands?

A: Because it uses high-quality dyes to achieve the dark color, you might notice a bit of tinting on your hands while mixing. This is easily washed off with soap and water and is a small price to pay for the “stealth” advantage!
