The Dynamite Evolution Krill and Tuna Oil come under the beady eye of Angler's Mail tackle editor Richard Howard. He's the No.1 products inspector, checking out loads of quality kit every week.

Description: PVA-friendly, natural fish oil bait additive.

Ingredients: Omega-3-rich winterised fish oils and betaine.

My verdict: accompanying the already established Tiger Nut, Citrus, Hemp, Robin Red and Smoked Salmon Oils, these are two obvious additions to the range, designed for carp anglers.

I’d happily use them, as I’ve had success with some of the other flavours, having witnessed how they can get the carp ‘troughing’ your feed.

The pointed nozzles on the bottles can be pushed into PVA bags, helping you to give your feed a liquid boost just before casting.

You can also oil your boilies, pellets, spod mix and floaters. When fish are eating your feed, the oil will rise to the surface, creating a flat spot in choppy water, indicating that a take is imminent.

Price: £4.99.
