Garmin GPS
« on: November 08, 2010, 08:17:38 PM »
I'm looking into getting a GPS unit.  Anyone have any experience with the Oregon 450 or the new Garmin 800?  I've read most of the reviews on MTBR.com but I'm looking for some local hands on reviews.  Thanks

I don't own or have any direct experience with either.  My opinion is the price is too high and the accuracy is too far off for Mt Biking.  Recently I saw a blog/post from the Breakdown.  Some how the 60 miles came out as 53 miles on Garmin 500. Maybe it dropped a few switch backs?

Since I already bring my iphone on all of my rides and I do not want to shell out another $250 or $450 for the 800, I bought:

1) the tigra handlebar bike mount case,
2) the ant+ adapter for my iphone from Wahoo,
3) the Wahoo bike speed & cadence sensor
4) then downloaded the Fisica app and until the battery issues are resolved - turned off the gps tracker.  

Now I can have one device for all of my bikes plus I can text like a teenage girl!

So one year from now will I be risking my iphone in a pisgah full immersion creek crossing or back with the disposable $40 bike computers?

My advice is to look at this new ant+ standard

My 4 year old Edge 305 said that the Breakdown was 59.07 for me - I was excited at how close it was, but I have some age-related issues that have me considering the 500 or the 800.

My hopes are that the GPS receiver part would be even better than my trusty 305, not a step backwards!

My Dad has the 500 but only does road riding.   In that arena, though, it is VERY close to his old wheel-sensor cyclometer.   And I *love* the mount for the 500.   SO much better than what I've been dealing with!

Anyway, hope these ramblings help in some fashion!   :D

The ramblings help. ;D I don't have an iPhone so that option isn't open.  I guess I'm deciding between training functions or waypoint/mapping ability.  I've considered the Edge 500 but I read in some earlier posts that  people were interested in the 800.  I was just seeing if anyone has had hands on yet.  Perhaps it would be the best if both worlds.

Thanks for the heads I up John.  I haven't looked into the GPSmap series.  I'll do a little digging.

I have the Garmin 305 and it works great but mileage is always short. I think it is because it does it point to point so it cuts off corners a bit. The mapping and stuff is very cool though and can be used for running too if you are into that stuff.

My wife bought me a garmin edge 605 a few months back. Love the thing!
I think there's a way to load other maps onto it, but it's a bit involved, I haven't figured it out yet. Not as easy as the Oregon series I think.

The thing I like about it is when you upload all your saved rides onto the garmin website (or software you put on your computer), it will overlay your route onto google maps, keep track of your distances, climbing, speed, put it all into a calendar, & show you reports of how much you've been riding. Pretty cool.

Moved to Idaho....:) Now I actually *mountain* bike.

Oh, and for those who worry about mileage being exact, my Edge 305 has a wheel sensor that can be used as well (for when cover is dense or when using the bike in a stationary trainer).   This wheel sensor also has the pedal cadence sensor in it as well.

I'd assume it's available as an option on all of the Edge models?

I had a 305 and loved it. The battery got to the point where it wouldn't stay powered through a long ride.  I decided to swap the battery myself and managed to kill the thing. 

There is a guy on eBay who refurbs 205's and 305's for $30.  Shoulda done that! The battery he uses has more capacity than the original. Many people experience shutdown of the unit when they hit a hard bump. He fixes that too. He makes them better than new. Really kickin myself on that.   :'(

Been researching the new Garmin Edge 500's and 800's.  The Garmin forums are filled with problem reports on both.  It's a huge turn-off.  People posting all the things going wrong and bug fixes they are looking for in new firmware, etc.  Sounds like you can forget about using the "Courses" feature on the 500.  Turns it into a brick. Or so they say.

Seriously considering a refurb 305.  Still have my cadence sensor, speed sensor and HR sensor. Extra bar mounts too.

I know the 305 inside and out and love the features. Power hub not in my near future either.

Anyone have any time using a 500 or 800 from Garmin? Problems?

A refurb 305 would be $200.  A new Edge 500 would be $250.  Tough call.

Thoughts?

Are you talking about the Garmin Forerunner 305?  If so you can get a new one for about $120, sometimes less.  I found mine at Wal Mart on line for $99.

Sorry, Edge 305.   :)

Just thought I'd share my new method for mounting my Garmin eTrex.  Garmin makes handlebar mounts, but they don't do what I want. (Easy on and off the bike in a few seconds; mount on stem to save room for lights / cyclometer).
What I used:

-RAM mount. $10.
http://www.ram-mount.com/ramgps.htm

-Hurricane mini pump strap. $4  (Padded velcro strap from performance bike)  They sell them in the store as well.
http://www.performancebike.com/bikes/Product_10052_10551_1031066_-1___

-2 strips of velcro ties to wrap the hurricane strap to the GPS mount.  stick a little rubber or something soft between if you'd like.

-A little rubber from a bike tube  to prevent the  hurricane strap from slipping around your bike stem.

Here are a couple pictures...

Just thought I'd share this too...this guy's setup is similar to mine, only much cleaner and more sturdy.  But I wouldn't want to re-do zip ties if I switch it from bike to bike...

I'd like to add the following comment:
I don't seem to have good luck with the accuracy on GPS trip info.  I trust my cyclometer.  The only time I go through the hassle of mounting a GPS unit to my bike is if I'm going somewhere unfamiliar and would otherwise get lost!

I also have an eTrex.  I used it ton when I was in the Boston area for 9 months and frequently did solo rides in unfamiliar areas.  I would plan ahead and add waypoints.  When I could find them I would download tracks that other riders posted.  Pretty cool the way it all works. Of course I always had a printed map and a compass as backup.

I never was crazy about the Garmin handlebar mount, but to my surprise I never snapped it off.

That Ram mount is nice.  May get one. I have some trips up my sleeve for this year.  :)

Something to also check for in GPS devices is the "refresh rate" (it might go by a different technical name) but basically as long as the GPS communicates your position frequently, about 1 time per second for good units, the unit will be fairly accurate, even on mountain bike trails.  When I was looking into buying a GPS for my mountain bike, some of the newer ones only had settings of every 3 or 5 seconds.  That's obviously fine if you're riding road or hiking, but traveling quickly on mt bike trails with all the curves and the like will tend to "straighten out" your ride if it only reports every 3 or 5 seconds, thus leaving the distance on the short side.  In the end, I've passed on buying one until I know for sure that what I buy is going to be really accurate.
