GPS Slim236 Time to Fix

If you are using it for walking try this http://www.pocketgpsworld.com/modules.php?name=Forums&file=viewtopic&t=33464 click the link in the first post, it might not speed up the fix duration but it certainly improves the unit when out of the car, I have never experianced more than a few (5 to 10) seconds to lock, possibly thirty seconds at the very worst when I first switched it on - Mike

I have been looking at the review on this one and I am thinking about getting one, should I buy something else instead. Seems there are a few problems at the moment or have they been fixed.

Can someone recommend a good unit.

Hi Mike et al,

I purchased this unit after advice from Mike following a bad eperiance with a CF unit in my Axim. I'm glad to say that i have had it for about 3 weeks so far and have not had any problems getting a fix at all. It even gets a fix within a couple of minutes after exiting the tunnel under the channel.

I can also confirm as mike has suggested that it works in the glove box of the car. This i was most impressed by. I know alot of the older units need clear line of sight into the sky.

Cheers

Mav

I have to say, I also think the 236 is a wonderful device, especially when you consider it can be bought for around £70.
I have had mine for around five months now and never had a problem with it.
The one possible exception being that if using it for walking you must wait for it to get a fix before moving. Once you have a fix then it's ability to track your position accurately is a revelation after using receivers with older technology. I use it with MemoryMap and if I check out my route on a computer after a hike I am amazed how accurate it is. My previous receiver ( a fortuna clipon) whilst OK for driving was almost useless for hiking because just when you most needed it to find your way it would lose your position due to foliage etc.
I think the problem with waiting for a fix before moving is a Sirf III characteristic anyway.

FWIW, "the problem with waiting for a fix before moving" is not "a Sirf III characteristic ..." I bought the Holux and got a problem, due to the generous return policy of the store I bought from in the State I was able to return it and bought the BT-338. The BT-338 has no problem getting a fix while you are moving and the fix is usually under a minute. Find a store with generous return policy and try for yourself. BTW, you don't see a lot of people with the same problem in the GlobalSat forum.

Just as a follow up to my last post, I found this post on another forum:-

I'm worried... I've just bought a bt-338 and my ttff seems to be *much* longer than this: I can walk down the street for 10 minutes -- the bluetooth cutoff -- without ever obtaining a fix. At the back door to my apartment I can obtain a fix (not moving), but it can take 3 minutes or more.

Might I have a bad unit, or am I expecting too much?

The next post after this one told him this was normal
and he shouldn't move before he had a fix. This sounds like exactly the same behaviour as my Holux. Except it has never taken me three minutes to get a fix whilst stationary.

I think a lot of these problems could be down to atmosphere conditions because when I first got my 338 it was really good than a while back it was taken longer to get a fix and locking onto less sats but now its really good like when I first got it

I've had my GPSlim 236 for about a day now, so early early days but it seems to lock on the satellites within a few seconds. I've not noticed any problems at all with it. I'm well happy with my purchase but I'll keep an eye on it to see if it changes. So far, so good though.
