mgraber: "I just got an etrex20x to replace a Lowrance unit that had been beat to death for years and was acting up. This unit is definitely not as user friendly but is light and compact with very good battery life. My question is how do I mark a waypoint at the cursor position? Is this unit even capable of that? It has been a long time since I've had a unit that did not have this capability so I hope there is a way. It is great to mark campsites etc. before you go."
I'm pretty sure you just depress the cursor button for about two seconds. There's also a mark waypoint command in the menu.
I have the 30x and, other than an electronic compass and barometer, it should work the same.
I find these units to be optimal in the sense they are compact and have excellent battery life. I don't care about mapping GPSs. The detail is just not adequate and the constant map re-draw is onerous on the battery. I just need a point to shoot for and the compass screen. I like to know my speed, distance, and ETA to the next waypoint or destination. But it's all a matter of personal taste.
