You need to have good picks but that isn't the most important factor. A good betting system for picking the right team the majority of the time is key and it doesn't matter if You pick Your own teams or You buy from a good handicapper, You still need the right tools.
This advice is for those that go to Vegas and want to bet many sports bets. The majority of People will do this in one book and Vegas loves those People. Vegas hates People like Me but I am trying to win my sports bets not please the Las Vegas sports books. First thing You have to do once You have the very affordable most important Betting tool is pick three (or more if possible) sports books to compare to place Your bet. You might want to brush up on who owns each sports book
If You are going to stay in one primary section of Las Vegas, You can set the order of the sports books You want to compare so that when You use Your app, the sports books are the first three that pop up. However, You can slide Your finger across the screen to see as many as You want. So now You are all set to take the small edge that Vegas Sports books have on You and You need to know what sports books to look at depending on Your location at that time. The reason You want to be close to the ones You are comparing is two fold: one, You don't want to wear Yourself out walking all over Vegas, Two, You want to get to the betting window quickly so the odds are still the same.
This spreadsheet is to help You see what the closest sports book is to where You are but not one that is the same odds. At Mandalay Bay of course Luxor is the closest sports book but it is also a MGM property and has the same odds so I tell You to cross the street to Tropicana.
The list starts at the far south end of the Las Vegas Strip and works its way all the way to the North to the Stratosphere and then downtown and east and West of the Strip.
When You use this app in the Vegas sports books they will ask You to leave so do not flaunt it, don't brag out loud about the line being better across the street, just leave, get Your bet, come back just like You went to the bathroom.
Just like counting cards is not illegal it is just not allowed in most casinos and the casino can ask You to leave and sometimes ban You from the property. Plenty of People are looking at their phones in the sports book so there is no reason You cannot use this tool inside the sports book just do not mock the sports book by saying anything out loud about it.
You might see that I list Treasure Island differently than MGM that is because MGM sold T.I. to Phil Ruffin in 2009 and T.I. has it's own betting line.
