Anyone using a hand held gps unit for marking and finding caves that they would recommend?
I am not at all concerned about the roads and such, much more interested in marking interesting holes or using it to find caves by entering gps coordinates.
I want a unit that will give me the direct route instead of trying to either route only on land or using roads.
I use several different GPS's for flying and can tell you the really expensive ones are no more accurate than the cheap ones. What you want to look for is WAAS, I imagine almost everything is now, I'd bet your phone would do an outstanding job, may be as simple as taking a photo with Geotagging on?
Only thing Clinton did I agree with was having SA turned off, SA is selected Availability which essentially by "dithering" a timing signal reduced the accuracy for the civilian band. Disabling SA and when WAAS came along made civilian GPS awfully accurate.
Re-read your post, go to Wally world and get an inexpensive Garmin hiking GPS
Plus 1 on a plain old garmin. My old one recently died but even as old tech, it was accurate within 10ft if it could find 5 or more sattelites.
That's because you've never used one of these:Quote:

I've used Garmin Rhinos and the water resistant eTrex's, both have worked great. My Rhino lost its water resistance after my dog got ahold of it, then died with my zodiac when the bottom fell out... The eTrex I have now has seen plenty of water(rain and quick accidental submersions) without any issues so far.
I'm not easy on gear, ask anyone :)
I use a Garmin GPS Map 76CSx, they are a little older model, but they are rugged, waterproof to 1m, which I accidentally tested, and they float. I would highly recommend one, especially now since you can pic them up used for cheap.
However, all garmin products I have dealt with are top notch.

Garmin makes superior products that are available within a wide price range. I have used this brand since the 1990's. You do want a GPS device that can receive the dedicated WAAS channel. Plan ahead before you purchase one, you will probably want to download coordinates to your computer and use them within various software programs. You may also want to upload coordinates and custom maps to your GPS.
I like my Garmins, both the automotive units and handhelds. I bought my first eTrex WAAS handheld to find sites in the local lakes. One site is an old homestead in 70' of water. You almost always have WAAS on open water that allows good coverage lines. First time with coordinates I had gotten from random source and I hadn't tested, I dropped the anchor within 15' of the target. I'll never repeat that was the thought of myself and my kids ;-) The next time, I was in virtually the same spot.
My Garmin eTrex was going strong for 8 years until it was confiscated by customs coming out of Iraq. Booooo. Now I just use my phone and a GPS app.
My Garmin eTrex is great. FDEP used these to collect tarball sightings for daily oil spill recon along the the beaches along the Gulf. The data were delicious. Definitely a solid investment.
I really like my Etrex Vista Hcx. The cool thing is it fits like a glove in an old Sony P something camera housing, which I am sure you can pick up for nothing these days on Ebay.
+1 for Garmin eTrex. I didn't need it, but BassPro had knocked it down to a rediculously low price around X-Mas, and it had been updated to a green body casing instead of yellow, but it is the same waterproof unit. Nice for kayak and inflatable boat cave hunting. waterproof to some extent, never flooded yet.

we just bought a garmin eTrex 10... pretty good, user friendly, however I think the numbers we got from tampa diving were not accurate, as we did a muck dive for an hour with no luck finding our hidden hole. The only downer to this gps was there was no reference points or maps... but if all you are doing is trying to find a specific point, this is a great model.
