Until now, there have not been many pattern choices or a difficulty level between 'House' and 'USBC Sport Bowling' patterns. USBC's Sport Bowling is a good description of difficulty but the definition of 'House' only means what bowling has given to it. Even though we realise that means easy lane patterns, to beginning bowlers that description means nothing. With all that in mind, Kegel has created a series of patterns called the Kegel Navigation Patterns.Read more at www.kegel.net

 All of the Kegel Navigation Patterns are grouped and separated by three levels of difficulty; Sport, Challenge and Recreation. The Kegel Recreation Series of oil patterns are ratios of 5:1 or greater, the Kegel Challenge Series oil patterns are ratios between 3:1 - 5:1 and climbing to the top of the ladder, all Kegel Sport Series oil patterns are USBC Sport Bowling compliant which adhere to ratios of 3:1 or less.

The Kegel Navigation Patterns are available in Kegel's Pattern Library on www.kegel.net to view and download for free while Kegel's award winning Technical Support department, Lane Maintenance Central, will be available for questions and to assist in setting up these patterns in your bowling center for your customers.
