I can go down to the shore and operate for POTA and WFF easily, all on a salt marsh :)
The antenna itself is based around the Slidewinder Coil. This is available in several colours to suit your mood ;)
This is extremely well built and based around a 3/8 thread unlike some other portable aerials. You can match this with a whip of your choice or go for the Slidewinder Military Whip option. I have this and it works really well. You can't adjust it in quite the same way as a telescopic whip but you can fold over a section if needed. I suspect that in the long term, the Mil whip will be more robust as telescopic whips tend to bend and/or crease over time.
There are several mounting options. Obviously as it is based around a 3/8 thread, you can mount it on a magnetic mount or other vehicle mount. M1ECC Antennas, who produce the antenna, do a roof bar/balcony mount, as well as a ground spike and a tripod option. I have the ground spike and the tripod and both work well and are solidly engineered.
The aerial works really well from 40m to 10m and I have zero complaints. I have never needed to guy it so far but I suspect in a solid breeze, it might be a good option. Tuning it is a breeze. Some people simply slide the collar for maximum receive and then use a tuner. I am a little more OCD about it :). I like to use my Rig Expert to tune it. Doing this enables me to get whole band coverage at under 2:1 across all bands, including 40m! You soon get used to where to start with the collar and then it is a simple job to tweak until you are happy.
I did find that with the aerial on the roof of the car, mounted on a triple magmonut, that the base sWR was quite high. This is not the fault of the aerial but a lack of ground. A counterpoise or a couple of radials would probably resolve this but it does work and in an area where getting an aerial out is difficult, would be a useful way of mounting the aerial.
Again, the service from M1ECC Antennas is superb and their communication is excellent.
One new option is a short 300mm/1ft extension bar. this goes between the mount and the coil and raises the coil. This makes it easier to get to the coil and I am hoping to test one very soon to see what difference it makes. I will no doubt do a video for this when I do.
I can recommend this antenna system wholeheartedly. In the meantime, here are a couple of videos about it.
