Double tap to mark hole location

Prior to stepping on the green, you must set the flag location relative to the location visible when you are close enough. The flag must be set manually.

Then what is the point of the double tap to mark the flag feature??

My point. Here we go again:

forums.garmin.com/.../pin-location

The tap is to mark your putt location on the green. The flag must be marked to where it is set for the day, as it changes daily and the watch has no way of having that specific hole location loaded to it beforehand unless you manually set it. 

I’m not fully following here..

while on the green, you can press the big red button, that marks the putt!

You can also double tap the screen to mark the flag, so why would I need to mark it before I step on the green? What is the point of the double tap to mark flag feature, if I have to mark it beforehand anyway?

The actual flag location is marked using green view with the touchscreen moving the flag to the location set for that day, and must be set prior to stepping onto the green. Tapping while on the green uses the flag as a marker to confirm the shot location. It is crucial to set the flag location prior to stepping onto the green to have that marked and viewable from the scorecard after the round. 

This feature was added much later after the design of the Approach S70 and initial feature set advertised. The feature was worked into the initial design of the watch to offer at least some option of manually marking putt locations during the round.

You previously wrote:
“The tap is to mark your putt location on the green.”
“Tapping while on the green uses the flag as a marker to confirm the shot location.”
Just to clarify—when you say “tap,” do you actually mean double-tap?

Because according to the release notes for 16.55:
(https://forums.garmin.com/outdoor-recreation/golf/f/approach-s70/364143/approach-s70-system-software-16-55)
- "Added the ability to mark the hole location by double-tapping the touchscreen in green view."
- "Added the ability to mark the locations of putts by pressing the action key in green view."

Based on this, double-tapping the screen marks the hole location, not the putt location. That aligns with what I see when using the watch:
- Pressing the action key while on green says “Marking put location” and shows a cancel timer.
- Double-tapping the screen while on green says “Marked hole location.”

So could you please clarify:
Is the double-tap not meant to mark the hole location as the release notes state?
If, as you said, it’s used to “mark your putt location,” then what is the actual difference between that and using the action key?

I have had my watch S70 for 6 months now and love it, however i have not used the green view until the last 5 rounds,

also i use the paid contours map but its also clunky if you are unsure of pin location and your location in relation to the pin its still just a guess of your path the the pin.

I will probably drop the paid contours soon,

I use the ct10, but do not have one on  the putter yet, i think i will start to use the ct10 on my putter soon,

Today played 9 holes here is my experience.

Hole 1: as I walked on the green I walked to the pin and Double tapped the green screen and the watch marked the pin location, I then continued to my ball that was off the green and the watch displayed the correct distance to the pin, I hit the ball walked to the ball on the green and hit the orange button on my watch and the putt location was marked. i 2 putted for a 5. 

Side note the watch did not record my chip shot, I believe this is because the watch thought I was already on the green because I marked the pin.

I two putted but the watch thought I 3 putted because in my opinion it recorded my chip as a putt.

after the round I reviewed the hole, in fact, the chip was not recorded, but the flag was displayed in the correct location om the green.

Hole 2: on the green in 2, walked to the pin double tapped the green, screen pin marked, walked to ball marked putt. made par

the correct pin and ball location were displayed on the map after the round.

my hope is after i install the ct10 on my putter that I will no longer have to mark the putt, I should be able to walk to the green, mark the pin by double tap, walk to the ball hit the putt and the ct10 records the action.

I think I will just have to put up with the glitch of marking the pin location with a double tap and walking to my missed approach shot and hit the chip without the watch recording the chip shot, I love the fact that I know what the exact distance to pin for my chip shots.

I find that trying to mark the pin location on the watch from off the green is useless, I can never guess with much accuracy from 100 to 150 yards so i just go with the front center back yardage and then kind of guess the true yardage.

what I am really wanting out of the watch is how far did my shot on to the green land from the pin, how far is each of my putts and how many times do I one, two and three putt.
