I have long reflected this purchase was mainly intended for offroad motorcycle. After much research and comparison I think my choice was the right one. The large display is readable, I can use it with gloves, rolling and seal tightness is perfect for my job. The possibility of batteries or battery allows me a completely adapted autonomy. The only complaints were assimilated prior to purchase, ie the obligation to buy cards in addition to the unit and the total absence of a full record. Last remark in "Trace" as I use very often, ie it records my course so I can then analyze my return home, he cuts it is not applied consistently. I have no point of comparison with other GPS hike but my job is almost perfect and the price on Amazon was unbeatable. The delivery was perfect (2 days) So I recommend buying this device on this site.
