Is a compass and barometric altometer that useful? Is a compass and barometric altometer that useful?

I, too, opted against the barometric (as opposed to satellite-generated) altimeter and the electronic compass, but as a Search and Rescue volunteer I have pretty specific needs. The barometric altimeter, according to Garmin tech support, is good to 70 feet, which is about two 40 foot contour lines. If you're asked to "search along the 5000 ft contour line for one mile, and return on the 5200 ft line," that amount of error is unacceptable. (The satellite-generated elevation error is twice that, plus.) I discussed the electronic compass with a fellow SAR member, and she was disappointed with hers: according to her, the accuracy we need just isn't there ("accuracy means different things to an engineer designing a GPS and a searcher - for us, 93 degrees must be 93 degrees").

If you're asking if it measures distance, no. It is for leveling or making sure many items are lined up.

With the use of a lighter or some object to heat up and you can adjust the compass. I am using perfect.

Altitude is part of the position calculation, and almost all GPSs can report it. Altitude error is about twice location error, so not too accurate. An altimeter/barometer greatly improves this accuracy, by correcting for oscillations in indicated altitude. They figure out the barometric pressure, so the slow weather changes are corrected out. Plus you can predict weather from the barometric changes, if you study them carefully enough.

I see you are right. Guess need to remove case for compass to work right. I had not used compass.

No I asked also. With a compass, you look through the eyepiece and and fix the compass wheel point to line up with a landmark you want to get to. You then have the direction, north, south, etc to follow the compass line on.

Yes, only one pole. Neither the compass nor thermometer really work and the pole sections jammed up on me so it would no longer collapse after only a few uses. Pretty cheap unit, but with the price it's what you're paying for. I recommend other options.

A satellite finder helps sometimes, but is not necessary. The elevation read out is very accurate and I use my GPS to tell me my direction (not a compass).

I do not think so, but I am not sure. I have not seen anything with a reference to a barometric altimeter.LV

Based on the reviews and answers here, I have to assume there is not a truing bar with this cheap of a compass nor instructions for truing it on your boat. Most compasses need to be 'adjusted' after installation to account for magnetic interference and metals around the installed area. I'll pass on this one, too.

In theory, satellite triangulation is one of the most accurate way of fnding your position, not only in coordinates (Latitude and Longitude), but in altitudes as well. Altimeters in watches uses barometric sensors to measure air pressure to calculate altitude. I'm betting the 305 will give me the closest, if not accurate, altitude than the best barometer sensor watch in the market. Add the convenience of tracking and recording altitude, with your heart rate, time, pace, position and distance at the same time. Why settle for anything less?

The compass works great. I do not use the barometer so I am not much help there. I have multiple Suunto watches and this is my most favorite of them all! The alumiuium in my opinion is definitely worth it. It's touff enough to hit the trail yet nice enough to wear to work.

I believe that it does work, but more of a trinket. Would not rely on them for hiking or anything, but just for general compass okay. I got them for all the grandkids, nieces and nephews for stocking stuffers and they are all still enjoying them still:) Several of them put them on the zippers of their jackets.

This is just the GPS signal receiver, not a complete GPS unit. It works well, but specific features such as altimeter readings are going to depend on which iPod app you use. Many people end up using several apps, depending on need. I use Gaia w/ USGS topo maps loaded, which of course give altitude readings with the topo lines. The basic app that comes with the UltiMate gives speed and altitude readings, although I have no way of knowing how accurate they are.

Yes, in the GPS Sensor menu you can manipulate the display between the Compass, Altimeter, Latitude, Longitude, Time positioning was performed and the Barometer. http://service.us.panasonic.com/OPERMANPDF/DMCTS5_ADV.PDF#page=135

Don't know... haven't tried that yet... usually I'm looking for GPS coordinates based on maps and general topography... a lot of times when your in between high ridges being able to read a map; thus long/lat comes into play.... because the GPS can't pick up a signal..... both are good skills to have.

I have used this horn about 12 times thus far (bought this to scare away woodpeckers from my stucco walls). The length of time depends on both the number of times used and the length. A good barometer would be to compare usage of a similar size can of compressed air for cleaning electronics. Be forewarned, this air horn is very loud so be careful not to use in a closed in area. You could damage your hearing and those around you. Great for use on a boat.
