Question: Geocaching ... ? Would this be suitable for a way to do geocaching?
Document: I don't have the best eyesight, but I'd say you'll find it--like I have--easy to read the screen. The "night" mode for the GPS is excellent, and works like a charm.I've found that I use the Travel Companion in "landscape" mode more than in what I would consider the standard IPAQ "Letter-orientation" mode. Landscape seems to be the way that IPAQ designed the Travel Companion, because the front panel controls are labelled for a "landscape" design.
I travel by motorcycle, so space is at a premium! I'd been bringing my laptop on short trips, but ended up not using it as much as I thought I would. All I really needed was some way of finding hotel locations and phone numbers, plus some way to email or post photos when I had a wifi connection.Before leaving on a Canadian 2 week adventure last August, we decided a GPS might be helpful. After searching for a month or so, I decided on the RX5915.
It works great for geocaching as well. The only this I wish it had, were a slightly more powerful prcessor, but hey, now that the price is dropping, definately pick one up.
Anyone else know a way around this dilemma?
Don't buy this -- it locks up and quits talking. The Garmin 660 is much better in almost every way. That's what I bought after returning this one.
The 5915 is jam packed with useful applications starting with the GPS. The maps for my area (Chicago) are very current and I hear that HP and TomTom are working on a way to enable 5915 users to receive updates.
The IPAQ 5915 is fantastic -- easy to use, light weight, and very powerful. The Tom-Tom nav system has been wonderful for business travel. You can plug in the destination and trust it to get you there. It is remarkable the way it even allows you to deviate from the planned route and reroute you from where you are.
By the way, the version of TomTom software I use is 6.1, which I believe is latest.I used other GPS. Some other products show current elevation and car speed on the staus page. But Tomtom doesn't. Of course, this belongs to the category of "even better if....".
Some websites are very supportive of the smaller PDA screen. Many websites do not. Exploring websites on your PDA is more of a hobby or emergency measure than a practical way to surf. This is a generic comment about the web on PDAs more than a comment about the iPAQ.Bluetooth is okay, but configuring devices takes some exploration to figure out.
The only way you can successfully reconnect to the network is to do a soft reset and then reconnect. It's an inconvenience, but minor, in my book, as the 5915 boots surprisingly quickly compared to my old iPAQ 5555, and to turn the wireless back on is a "press" of the Wi-Fi icon on the main screen and you're back up and operating in no time.
Answer: I use my 5915 for geocaching. I wanted one device that I could use everyday in the car (nav, music, pda-functionality) and then could pull out for the occasional cache. I really like the program GPSTuner for offroad navigation (no affiliation, just a happy customer). I also bought a little silicon case on ebay to protect it on the trail. If you do a lot of hiking, etc, then a dedicated, more rugged GPS is probably a better bet though.
