Garmin eTrex GPS
If you like to hike back to fishing holes that are off the beaten path - like me - then a hand-held GPS is a must have tool to keep in your vest. I just upgraded my old (produced in 1999) standard, base model eTrex with the eTrex Venture HC (pictured below). The new device set me back around $170, but has tons more features than the old one.
The Garmin eTrex Venture HC has pre-loaded maps (although somewhat limited) and can download (for a price) detailed city streets, topographical and marine maps. I'm planning on getting the topo maps so I know whether that 1 mile hike includes several hundred feet of elevation change with it. I can't tell you how many times I have been burnt by my old GPS that didn't give an indication of the elevation until I was standing there. By then, it's too late. So far it seems to be accurate and includes some really cool "throw-in" features like the best time of day to hunt/fish, ability to add notes, color display, good resolution (not great, but good), stop watch, games, calculator and other stuff I will probably never use. So far I'm really happy with it. I looked at many other products, read other reviews, and this device got high marks even considering its low price.
Our 9 month-old Golden Retriever puppy decided that the old eTrex was better suited for chewing than mapping.
The display is black-n-white, doesn't allow for anything more than a flat "this is where I've been" route, has limited storage, very limited features, and my favorite: it didn't come with cables to connect to my computer. I had to buy a special cable after the fact. Also, there is no software so I had to find a free 3rd party application to help me transfer way-points to Google Earth. On the plus side, it is water resistant (for those days I take an unscheduled bath in the creek), has (or had) good battery life, and apparently makes a good chew-toy.
The culprit. A cute little chewing machine...
