How to Use a Marine GPS. Marine GPS is a necessity on the water since there are no roads, signals, or light at night to guide the boater from one location to the other.Without GPS navigation, it would be quite difficult for the recreational boater to get from point A to point B without any issues.he GPS devices with internal antennas are used on smaller boats with no top or cover since the receiver is built into the unit and it needs direct line of site to the satellites providing the signal to the device. The second ones are the external antenna units.
Step 1: Toss Verified Receipts and ATM Slips. Nearly all of your financial papers can be divided into three categories: records that you need to keep only for the calendar year or less, papers that you need to save for seven years (the typical window during which your tax return may be audited), and papers that you should hang onto indefinitely.
This is the perfect time of year to do some housecleaning with your financial records. You should be receiving your W-2 and 1099 forms this month, reporting your income and interest for 2007. In the meantime, you can start to get rid of many of your old tax records. It's a good idea to keep your tax returns forever. But you can usually toss the supporting documents, such as canceled checks and old receipts, three years after you filed your taxes. That's usually how long the IRS has to audit your return, unless you've left out a big chunk of income. If you have any self-employed income, keep the receipts for at least six years.
