GPS Compare
This is an old table I put together....circa 2004. I dug it up to go along with my updated GPS instructions. I hope it is still somewhat relavant.
...and the table breaks the site theme...I'm not sure why...sorry, it doesn't look too good...

quad helix tracks satellites more reliably - you don't want to lose your satellites while flying |

| Thumb Stick | N/A | N/A | Yes | Yes | N/A | N/A | N/A | N/A | N/A | N/A | useful in the eTrex's but not needed with the 12s and 76s - they have a cursor pad |
| Ext. Ant. Hookup | N/A | N/A | N/A | N/A | No | Yes | Yes | Yes | Yes | Yes | not needed when flying - useful while driving as satellite reception in cars is sometimes poor |
| WAAS capability | N/A | N/A | Yes | Yes | N/A | Yes | Yes | Yes | Yes | Yes | WAAS is a satellite in the Southern hemisphere - useful if you travel to comps down there |
| Glide Ratio, Glide Ratio to Destination | N/A | N/A | N/A | Yes | N/A | N/A | N/A | Yes | N/A | Yes | VERY useful when trying to get to goal - doesn't take wind into consideration though… |
| Electronic Compass | N/A | Yes | N/A | Yes | N/A | N/A | N/A | Yes | N/A | Yes | A battery killer and not needed while you are moving. barely handy on the ground either. |
| Barometric Altimeter | N/A | Yes | N/A | Yes | N/A | N/A | N/A | Yes | N/A | Yes | all models listed here (other than the Garmin 12) records altitudes - great for flight analysis on a computer. Gets you more points for your HOLC scoring. Barometeric altimeter improves accuracy in the altitude calculations for final glide. |
| Proximity Waypoints | N/A | N/A | N/A | N/A | N/A | Yes | Yes | Yes | Yes | Yes | can set 400m radius around turn points so it can alert you when you are successfully in sector. A definite competition advantage |
