Pool Swim - default GPS location

lopey66 said:

A simply way to introduce GPS data is to have a default GPS location for the Pool & actually 2 points one at each end of the pool.

GPS does not work indoors, hence it would be useless. If you swim in an outdoor pool, you could use the Open Water Swim activity. 

truxdid you understand what I was suggesting, I know exactly what my watch is recording, Pool activity is using swim metrics to measure a defined pool lap distance, I was at an outdoor 50m pool, I don't use the open water swim as it is not as accurate measuring the distance and cuts short the distance and thinks is due turning around at each end of the pool and poor GPS due to the hand being in the water.

here is my swim 2,150km swim an hour earlier I have done this deliberately just to show you and others on what can be done (I sure someone is going flag my swim), it has been transformed into a circular swim, if you look at my strava activity https://www.strava.com/activities/10997049443 its100m per lap loop.

No, sorry, I think I did not, and frankly told, still do not understand. If you just want the location on the activity screen, then there is nothing simpler than using the Multisport feature:

1. Start the Walk activity for a few seconds when still out of the water (or at least having the watch above the surface). Would work even with an indoor pool, if you start the activity in front of the building.
2. Use the "Change Sport" function (I believe on F6 you need to define a Hot Key for it)
3. Select Pool Swim a do your workout

When finished, save as usually, and sync the activity. When you then open it in Garmin Connect, it comes with the map.

I think you are asking for functionality similar to how diving activities on Descent series devices automatically record GPS locations at the start and end of the activity. That would allow for recording the locations of pool swim activities, at least for outdoor pools where you have satellite reception. Garmin isn't going to add any major new features for the Fenix 6 series but you might want to suggest it as an idea for a future product.

this image below is a walk of my activity around the 50m outdoor pool whilst lifeguarding & I never entered the water, what I am trying highlight is the poor quality of data and as another person suggested using the "Outdoor swim activity" and is more to the issue of the ends of the pool and will cut short or make it longer, by having fixed coordinates for a pool swim and you are literally swimming to the same 2 points, I have my personal app where I recreated the swim as circular loop (100m=circumference see image below) https://www.strava.com/activities/10997049443?utm_content=412790&utm_medium=referral&utm_source=twitter   

I am afraid I do not understand at all what you are trying to do. Do you want to record walking around the pool with the Pool Swim activity profile? Why don't you simply use the Walk activity for that? Whether the GPS track is accurate or not, does not matter much, since the distance is being adjusted with the help of the accelerometer anyway, when the GPS signal is not perfect. And what exactly is the ring in the middle of the pool good for?

@trux  you really don't read, I walked around the pool using a walk activity and I repeat I did not enter water, that is how bad the data it. what you refer to ring is the circular loop of the recreated activity of the swim activity now as like it was outdoor swim activity, every metre has been calculated for 2150m with latitude & longitude points and that I finish on 50m end, the end point is on the dot(finish line flag) and not the start point(green dot).

to summarise 2 activities record at different times, one walk activity and the other a swim pool activity and rebuilt into a GPS mapped activity.

You did not write that . You wrote:

There is no mention of "Walk Activity". You tell it is a "walk of your activity around the pool" while referring to OW Swim  activity in the same sentence. 

However, it is unimportant. The quality of the track is rather OK, not bad at all. The claimed accuracy of GPS on Garmin's watches is between 3-10 m under good signal conditions [source], and your track fits into the margin without problems.

As I already wrote, the watch does not calculate the distance with GPS only. It combines GPS data, and data of the accelerometer & gyro sensors, so these small deviations on the track won't make much effect, assuming your watch is already well calibrated.

As I told that's exactly what Multisport activities are made for - you can combine two different activities into one with this feature. Look it up in the manual or in the following article. Using the "Change Sport" hot key is definitely easier than creating a custom multisport activity profile in advance, so I suggest using that method.

I have always used "pool swim" for more than 10 years (910xt) and have only used outdoor swim on few occasions & in ironman races, hence the reason for the original post as a suggestion in regards to a pool swim activity and recording Latitude/Longitude predetermined before you start the activity and not wanting to mention GPS, as you mentioned just going back and forth

The image below is of the original activity(strava page screen capture) rebuilt into a hypothetical outdoor swim activity where I am swimming in loop/circle/ring ,the graph shows the distance, so if you moused over the graph you would see me going around in circles on the map, I could litteral build any route path and overlay data, I used a circle deliberately to show what is possible and one point is required.
