Delkim was formed in the late 1970s when carp anglers Del Romang and Kim Donaldson discovered flaws in the bite alarms available at the time. Many anglers still had to rely on the Heron antenna alarm, designed by Dick Walker in the 1950s. Despite it being 20 years old, this alarm was still considered state of the art as it was practically the only one on the market for carp anglers. Del used his engineering experience to modify the alarm. It soon got him noticed by the other anglers at his local fishery – Darenth, Kent – and they quickly came to him to request he make the same modifications to their Heron alarms. The Delkim Heron Conversion became a commercially available product, and anglers from across the country, trusting the excellent reviews, sent Del Romang their Heron alarms to modify with LED’s and GPO speakers.
Around the same time, Del began experimenting with making his own bite alarms, which he, Kim, and their friends, used for many years. He considers these to be the first Delkim products, and, although they aren’t used any more, they are still in working order. All of Delkim’s current products have a two-year guarantee, but as you can imagine most are able to last much longer.
In the 1980s a new bite alarm emerged, the Optonic. Being the first alarm widely produced since the Heron thirty years earlier, this alarm was considered to be revolutionary. However, many anglers found it had major deficiencies, so came to Delkim to see if the alarm could be modified. Delkim produced an innovative conversion which was to set the standard for bite alarms produced today.
In the early 1980s, Del Romang invented Delkim’s first ever own brand bite alarm, when he threaded a string of fishing line under the needle of his record player. Not wanting to jump the gun and produce a flawed alarm, like the Heron and Optonic, Del spent nine years developing his product. Only once the product had passed his intensive testing regime was it patented as the Delkim Vibration System. This was truly a revolutionary piece on angling equipment and is the still the base that the current Delkim Vibration Alarms are based on. Recently Delkim have also began manufacturing innovative accessories to support its bite indication products, meaning it has the most comprehensive portfolio of bite indication equipment on the market. Its website features testimonials from some of the biggest names in fishing, all of whom swear by Delkim bite alarms.
Angling Direct have the full range of Delkim alarms for sale, with several deals on the ever popular TXI plus, the TXI has received global acclaim and is the best selling Delkim bite alarm to date. The TXI gives proportional indication of the line speed and vibration without any moving parts, meaning the TXI gives incredibly accurate readings every time. It is impossible to get these kinds of readings with any other bite alarm system, as most other systems use a roller system that is only capable of detecting a running line.
The newest alarm in the Delkim range is the Txi-D and RX-D receiver, the Txi-D interface has been redesigned, the alarms now feature just two adjustment wheels, volume and response, allowing you to set the response level of your Delkim set up. The sensitivity and tone adjustment wheels are gone in what is now a streamlined setup.
One small complaint of previous Delkim models has been over-sensitivity, warbling at the smallest of line bites or in the case of a heavy storm, the water movement would sometimes set it off. Delkim have found the solution to this problem - Digital Signal Processing (DSP). DSP allows you to customise beep speed, beep speed does not affect the response of the alarm, liners will still register but the pace of the beeps is slower which allows you to get a greater understanding of what is happening beneath the surface and prevents the Txi-D from warbling at the smallest of indications.
