Re: Which GPS unit for me?
Thumbs down on the recon smartphone app. Tried it last year, and I was not impressed. Smartphone GPS antenna are not as robust as a dedicated GPS unit. Horrible reception in forested areas... poor acquisition speed. Battery life on the smartphone with the GPS running is poor as well. And, you'll need some way of recharging your smartphone in the field on multi-day hunts.
I'd stick with Garmin or Magellan that use standard AA batteries. I use the eTrex 20, which has expandable memory. Don't waste your money on a more expensive unit... unless you need other built-in features, like camera, 3-axis compass, wireless sharing, etc.
