The initial launch of ESP Cryogen hooks in March 2016 caused a massive stir with discerning anglers quickly recognising the distinct technical advantages they offered. They were the result of over three years of development and field testing which culminated in a new standard in strength and point durability.

New manufacturing techniques including both high temperature and cryogenic tempering have produced significantly stronger hooks with more durable, long life points.

Cryogenic tempering is a process used to improve the molecular structure in steel which in turn reduces stress and improves strength and wear resistance. It is used in many disciplines with Formula 1 engine parts being a classic example.

Bench tests on initial samples proved to us that the new tempering processes combined with improved designs and heavy forging resulted in hooks that were 25-30% stronger than other PTFE coated carp hooks in the same wire gauge. We subsequently sent the hooks for independent scientific testing on hardness and tensile strength and the tests carried out confirmed and supported our initial findings.

So rather than having to improve strength by simply increasing wire gauge, new manufacturing processes have allowed us to maintain optimum wire gauges for each size which allow for fine, ultra-sharp needle points which are now more durable than ever.

ESP are now delighted to introduce three new patterns into the Cryogen range, with each type having been developed, tested and ‘tweaked’ over the last 18 months. They have proved outstanding in field testing and provide an even greater choice in high performance, long lasting carp hooks

This is the same classic curve pattern previously available under the ESP Raptor banner but this new range has been made even better by stepping up the wire gauge in each size and giving them the bullet proof Cryogen treatment. So these Curves are now around 25% stronger than their predecessors while still retaining long fine needle sharp points which are now extra durable.

The Curves are highly effective in a whole variety of rig presentations (perfect for the Ronnie Rig) and their quick turning, anti-eject shape combined with a needle sharp point ensures exceptional hook holds.

Available in barbed sizes 4, 6, 7, 8 & 10.

If you order an item and it isn’t what you expected then we’ll happily take most products back (within 14 days from date of receipt) as long as it is in unused, as new condition and in its original packaging.

Please note that ALL non-faulty items must be returned in saleable condition and in all original packaging otherwise a larger restocking figure may be applied as we will be unable to resell the item as new or at anything near its true value.

For some items, such as made-to-order, special ordered items or personal use or hygiene products unfortunately we are unable to take the products back. Additionally, cancellations of special order / made to order items may incur a restocking fee. If you have any queries, then please call us to ask for further details.

The Customer shall comply with the ATG Fishing returns procedure as defined below. ATG Fishing will not accept any returned goods should the returns procedure not be followed.

The Customer must contact ATG Fishing by either telephone or by e-mail to obtain a returns authorisation. A returns code will be issued and must be referred to in all correspondence. This number must also be clearly marked on any returned packages. The customer is responsible for returning the goods with 14 days of receiving the item.

In cases where the faulty or damaged goods are rejected within 14 days, the Customer is entitled to a replacement, alternative goods or a refund. The faulty or damaged product must be returned to the location specified by ATG Fishing before the refund or replacement can be issued.

All refunds will be issued within 14 working days of an order being cancelled or items returned.

ATG Fishing accepts no responsibility over returns shipping costs for rejected items unless they are faulty in which case ATG Fishing will cover the normal cost of returning the goods via tracked post or courier but will not cover the cost of express, next day, Saturday, am, special or any other form of expedited delivery.
