Garmin GPS Review
Review Date: June 27, 2009
Reviewer: M. Leeper,
In the GPS realm, in my opinion their are only two companies to consider, they are Lowrance Electronics and Garmin. Upon a close review of available products, the Garmin wins hands down because the 400i Colorado has all of the cadilac features of those of the Lowrance Endura products but at a price that will shock you. Both the Lowrance Endura GPS and Garmin Colorado 400i GPS lines retail around $500 from the factory and their foo foo outlets. Thru this site, you will find you can purchase a Garmin Colorado 400i for $312. and get the product in less than a week. The Garmin has capability for easy downloading of topo maps and even turn by turn directions while driving. This is my third GPS unit over a period of the last 15 years and it is by far the easiest to use. I highly recommend it to all.
Use The High Capacity Batteries
Review Date: March 25, 2009
Reviewer: Loonman, Marblehead, OH
This unit is basically the same at the Colorado 400t, with a different preloaded map set. In the reviews for the 400t some folks have mentioned that the battery life is a tad short. Others have suggested using high capacity batteries. Both opinions are accurate. I like to use rechargeables and I have tested Duracell NiMH with an 1800 mAh rating, Sony NiMH with a 2500 mAh rating, and Duracell NiMH with a 2650 NiMN. I turned on the receiver, left the back light on the low setting, and checked it periodically, noting when each set failed. Obviously this is an approximation and I won't report the details but there was a significant improvement with each step up in mAh. It was measured in hours, not minutes. I wish that the unit ran longer on a set, that is a fact, but I will just carry spare high capacity batteries. I have not used this in the field but have practiced with it extensively here in my home area. So far it is a great unit, better than my old Magellan. The technology has improved over the years.
Great stuff

I purchased a Garmin 400i from Amazon, it has been a excellent product, the shipping came to my home in and near the time frame that was mentioned. I used the Garmin handheld Gps for month and I must say it has been fun and useful, since I am a bowhunter. I use the Garmin to scout and locate my deer stand hunting spots. I thank Amazon for making the purchase a breeze.
great electronic

I enjoy the many features this instrument has to offer. I take it to my parttime work, sometimes, and play with it when I am at the kiosk.

Reviewer: Grease is the Word,
The updated product is the Oregon 400i, which is currently 2x the price. Just as an FYI, not saying anything bad about the product.
Hello, My name is Peter OBrien and I love to travel around and experience new things and people.
When I am traveling, I always use my garmin handheld gps device. Garmin always gets me where I need to be quickly and safely.
Garmin also is great for enjoying some of my favorite activities like golf, fishing and hiking. These great gps units can make life on the golf course, lake or on the trail a lot more fun.
I have many garmin gps reviews on this blog with a star rating system and actual customer reviews.
