The Golf Insider reckons the bookies have a "chink in their armour" and they can show you how to profit from this blindspot.
Apparently, they have been delivering winners at massive odds since 2014, up to a staggering 200/1. The service has reported huge odds winners every year since the service started.
The main golf tournaments are covered, including the European Tour and PGA Tour. There are also some added bonuses such as a list of players to follow for the season.
We could not find a full breakdown of profit/loss results for the service unfortunately, so we can't tell if this wins resulted in an actual profit each year.
The tipster has been involved with running betting advisory services for over 20 years and all of his tips are proofed by a third party. He also offers a 30 day money-back guarantee, so you can get a refund if you figure it's not for you.
He has even included a landline and mobile phone number where you can contact him with any questions. This is a new one for us, as we have found it difficult to find contact information for tipsters on many occasions.
Although his identity has been kept under wraps, he is there for any support or further details on his bets.
One of the questions asked was "How does your computer ratings model and value machine give you, and someone who copies your targeted bets, a winning edge?"
In a nutshell, he explained how his system gives each player a rating and then calculates the correct odds for them, allowing him to find an edge in markets such as Tournament Winner, Round 1 3 Balls or Top 20's.
Bets are sent out by email, usually on a Tuesday ready for the tournaments starting each week on a Thursday. They come with full write-ups and the current best odds at bookmakers and exchanges.
We will be following the service over the next few months and will report back with our results on a monthly basis.
