I don’t think there’s a thread about these…
My Garmin TRI strap has stopped working again. Garmin replaced it twice but all good things come to an end and I need to buy a replacement strap which won’t be Garmin 
What are the recommended hrm straps these days? Wahoo seems to have some reliability problems like Garmin. The Coospo H808s looks ideal but not sure if it can be worn in water, does anyone know? I want to be able to wear it under a trisuit/wetsuit. Any others to consider?
Assuming your watch is a Garmin, if you want HR recorded from your swim, the only option is a Garmin strap (Tri or Pro, might be another one). It only syncs after the activity, so you cannot view HR while swimming.
If your Tri has died when you replaced the battery, the Pro has a new battery enclosure, which has worked for me on the one battery change so far.
If you don’t care about HR from the swim, then most basic HRMs should be waterproof, worth going for a dual Ant/BLE for max compatibility, especially with apps like Zwift. I have a CooSpo, and although I’ve never swum with it, it says it’s waterproof.
Thanks Buzz, I saw the new Pro plus after I posted and I’m tempted to give it a try.
Edit, purchased. I had a 25% discount code for the Garmin which only made it twice as expensive as the Coospo. Bargain, right? That’s right up there with MrsB’s maths 
I contacted Coospo support yesterday and asked if their hrms can be worn under a wetsuit. They replied this morning, “I’m sorry.Our product does not support swimming.You should check garmin heart rate monitor.”
Good job I got 25% off the Garmin then
anyone used one of these ,i have been through 2 off wahoo chest straps in last couple of years getting fed up with wasting money on them and keep changing battery
Sorry Stiv, can’t help you on this.
But I think I mentioned elsewhere that my Garmin Pro strap had got really erratic despite being only 20 months old. I got onto their support saying I was disappointed it hadn’t lasted long and got a typical first line response with a link to their web page with the usual suggestions.
Emailed back saying I’d tried them and still waiting for a response, in the meantime I’ve had a rate my support experience so I’ve let them have it 
I have been using a lifeline BLE/ANT monitor and strap https://www.chainreactioncycles.com/p/lifeline-bluetooth-and-ant-heart-rate-monitor since May 2022 without issue on the turbo. I have destroyed so many wahoo monitors that after the 5 replacements I discovered this one for 16.50 at wiggle. I turbo a lot so used daily and sweat a lot and it has been faultless
Need a working HRM with bluetooth. Anyone got one off AliExpress before? Obvs good prices but wondering if they’re just fakes and/or crap.
If not, any decent BF deals on one out there?
I have a COOSPO armband HRM bought off Ebay for £24. I prefer the armband type as I can never get a chest strap to sit comfortably on this ex-prop’s frame as they’re often too tight.
Works fine
You can buy them off eBay too. I like mine. It works well.
I got one of these off eBay. It’s still working, but it keeps turning itself on whenever it detects movement; as a result it gets through far too many batteries.
I know this because it beeps on & off, and when it’s in a bag it’s always peeping away.
COOSPO are a completely respectable brand, that’s their own store on aliexpress, so yes it’ll be fine, it works well for me too.
The H9Z which is rechargeable might be worth the few quid more to avoid the 2032 pain
Great to know. Will get the rechargeable one.
I bought their little bike pump thing off that store recently too.
Yes sorry was looking at that too quickly. I’ve got the rechargeable one. Holds charge. And doesn’t seem to have the spurious turning on that Jorgan describes. So I’m happy with mine.
