Questions you must ask yourself first, Fongy -
- Does it solve a problem that exists?
- Is the problem widely experienced - in other words, will the product sell well afterwards?
- What will be the end RRP and can it be made for a reasonably small amount of cash including prototypes?
Two examples, a friend of mine developed a new bait cup to dangle off a pole which had two problems - 1) other systems, pole pots, did similar job, were cheaper, less cumbersome, and already available. 2) it was grossly ugly.
Another idea has been dropped entirely by a manufacturer, but in this case it was a sound invention, so much stronger than the present method and anglers need this change desperately, and it would last thereby saving us money in the longer term. However, in order for it to sell you would have to change everyone's mind from using the present inadequate method to the new one and that was almost an impossibility with everyone selling the existing one and making vast profits. In other words, just because it's better doesn't mean it will sell. A bit like oil products really.
