@psychopengy for a short moment let’s play with an idea that your Orca-Pioneer was marked just like your handheld Silva: imagine that zero was right below N and 180 was right below S. Now imagine securing this kind of compass to the bow of your kayak so that the compass window and that notch in the housing faces back, towards you. If you were paddling straight towards north with a compass like this which number would be there under that yellowish or reddish line in the housing? It would be 180 but that’s wrong!!! You were heading north, but the stupid marine compass says you are going to the direction of 180 degrees! That is why the N E S W letters and their corrensponding numbers must be on the opposite sides. This is the logic: marine compasses are always secured in place on the vessel so that the colorful line in the window faces back (or aft). You can look at the marine compass straight from above and you’ll see the compass rose (direction of north, east, south and west), but the numbers under that colorful line ALWAYS indicate which way your bow is pointing! Just mount your Orca-Pioneer to the bow of your kayak (not right under your nose, but really to the bow) and start paddling. The number under that line keeps showing the direction you’re headed. When moving north it’ll show zero while the letter N on the compass rose is on the opposite side. I hope this explained the logic. Back in the days I used to have a scuba diving compass on my wrist and that worked just like marine compasses. There were actually two windows, one above and one on the side. From the top window I could see the compass rose and raising my wrist right in front of my face the side window indicated my heading. [image: 1698384205488-suunto-sk-7.png]

@sartoric aaaa ok ok, sorry

@Todd-Danielczyk Thx for your help!

Hey @Audaxjoe thansk for replying I‘m already the owner of different Bands (Color). The M/L size is tight on a 7mm wetsuit and (for me) impossible to wear on a drysuit. Looks Like I have to wait for XL straps

@Stoke80 yes, sorry for my english just found this https://www.youtube.com/watch?v=iUuuNgRAxhU

@Greennorth I bought a like of straps from AliExpress super cheap and they’ve been great!

@luke55 I have found Velcro straps give me better OHR readings than the Silicone ones. You can order 22mm velcro straps from Amazon and pins to add for holding the band. You won’t be able to change bands quickly but I prefer the Velcro bands.

@cosme-costa agree. Karoo is great.

I have the same issue, any idea how to fix it?

They don’t seem to be available, but someone found a clever solution: https://www.reddit.com/r/3Dprinting/comments/17g7kk2/finally_done_suunto_x9_x10_rubber_strap/?show=original Maybe that helps

This would be a good idea because the current offer for cyclists is very poor - e.g. sensors, import and integration of activities from other services and devices.

@Christophe-Roos I can confirm your observation: I have a Suunto watch and when it ran out of battery once, I thought I use the Smart Sensor belt on its own, with the app (this is possible with the Polar belt and the Polar Beat app). The app offers to record an exercise, but one cannot couple sensors to the app. You definitely need a Suunto watch between the app and the Smart Sensor.

@vinc14 Maybe because they have decided it according to market and default size for almost everyone is M. If not, they probably would need inventory for something they might not sold. Just guessing.

@martin720601 The Suunto smartsensor has only 1 bluetooth channel and no Ant+. It will only transmit to 1 device,

@herlas Never run that race (my daughter has) and I likely never will:). I will be out of town on that day.

@aamado said in Using Suunto heart rate belt for scuba diving: Hello Everyone, Can the Suunto heart rate belt monitor be used for scuba diving? I’m thinking that, when diving in cold waters, I won’t be able to use the HR sensor from the watch (not even sure if it works underwater!), so using the chest belt for HR might be an option. Maybe better with dry suit to avoid getting wet but not sure if pressure can damage or even break the sensor which isn’t something pleasant to happen during a dive! Any thoughts on this topic? Thanks, Antonio Interesting question. I have never dived with a heart rate monitor but I swim a lot with OWS and in the pool with a heart rate monitor. I think it can be done but only with the Suunto Heart Rate Belt because Bluetooth does not work underwater. The Suunto sensor has its own internal memory and can work independently with the watch after starting the activity. After finishing, the data is automatically transferred to the watch. If you want to dive with Suunto “OCEAN”, I don’t know because I don’t know this model. The only limitation is depth. According to the manufacturer, the water resistance is up to 30 meters.
