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.
If the total amount you are claiming is $300 or less, you do not need to keep receipts, but you must be able to show how you worked out your claims. You need to keep written evidence of your work-related expenses for five years from the due date for lodging your tax return. If you lodge your tax return after the due date, the five years start from the date you lodged your tax return. For a depreciating asset, you must keep records for five years from the date of your last claim for decline in value (depreciation). Last modified: 05 Oct 2016QC 26103.
