Garmin Colorado 400i Portable GPS System Review
October 5th, 2009
Garmin Colorado 400i Portable GPS System Review from Loonman. Use The High Capacity Batteries, 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.
