I know this is might be moved (hope not) to Gun Dogs
Traffic is higher here. And it's light traffic anyway these days so maybe this will spur some clicks.
Anyway, I would like to ask:

I have a DT Systems H2O 1820 that just crapped out on me for the third time in as many years.
I have taken it twice to their home office on Walnut Hill to get fixed. I'm not going back a third time.

What waterproof training collar systems do you swear by? And why?

Tri-Tronics

I think you would have got more relevant discussion down there, but your good. When I had hounds, tritronics was the bomb. My dogs put them through hell. Tritronics is now owned by Garmin. I use the Garman Alpha. Have never had a problem with any of them in or out of water.

I had a tritronics that lasted 6 seasons...I'm now on a SportDog that has made it through 1. I think Dogtra would be your other choice.

Seems if you stick to one of those 3 you should get good service from it.

Gsrmin has taken over tritronics. I am going to try it when the collars I have fail.

No problems with the garmin I am using.

Thanks all.
Going to buy the Garmin Pro 550

Used my tritronics on my dog 9 seasons, it out lived my dog. The button that turns it on and off does not work well, I have to like press it at an angle to get it to work, this started last few seasons. I need to call them on this, I hear their customer service is the best, they might just fix it for me for free. I should have called them when it first started acting up. I plan on using it on my next dog.

Garmin or Dogtra

I have two Dogtras. The oldest finally needs the batteries replaced after 10+ years.
