Poor GPS tracking at open water swimming

[Yurgo]

Hi to all! I use Spartan Sport watches and every time suffer because of very poor track during open water swimming. Sometimes watches gets more than 30% of estimated distance! How do I manage it?
Before training I do everything which is noted in manual to make GPS accuracy better. I switch on training meny to find sattelites in advance, than wait for 5 minutes to make sure that watches find it exactly and that start training, but nothing helps. To avoid misunderstandings my watches use maximum GPS accuracy as well.
I swim as crawl not brass so my hand with watches appears every stroke above water to catch signal but later when I see the track it looks shaped and if to compare it with Garmin Fenix watches for example the difference is huge. The second one showes more real track than Suunto.
So anybody knows how to deal with this problem?
