Hello everyone, I'm a newbie here however thought I'd post up something about a recent purchase I made. I ordered a SENA Prism action camera and a SENA 20s bluetooth unit. SENA PRISM - $389 - AdventureCamsHQ The main decision for choosing the Prism over a go pro was it's ability to record via the bluetooth directly onto the video. This appealed a lot more as I wanted to start doing some motovlogs so this was appealing. The GoPro, you can order a SENA bluetooth packpack which will do exactly the same thing but I liked rather than two devices just having the single. The GoPro does have a wider field of few so does make you "look like you are going faster" and get more in but that was small on my list of pro's and con's. Comes with a great assortment of attachments, waterproof housing and all cables and accessories you need. The only thing you need to do is put in a good quality micro SD card (Class 10) and you are up and running. I ordered the full pack and not the LITE version which is also available. I recommend to download the latest firmware when you get it and the device manager is simple and easy to use and can be downloaded from the SENA website. Going through the menu's, linking to the bluetooth unit was a breeze. There are videos, documents, tutorials all on the SENA website. PRISM - Sena I also like the flashing recording light to let you know you are on and I also like the fact that you can download the iphone APP and change the settings from there. I don't like the fact you can't view your recordings/preview them however I have heard SENA are working on a fix for that to be able to do it via Bluetooth. The GoPro therefore wins that battle. I went for a 30min ride and filmed the entire thing and came home it was 2.4gig of raw data. The design is simple, easy it is a really well built product and having used GOpro and other action cams it really is up there with the best. The choice between GoPro and SENA would be a personal one but for me as said the decision was made easy by having only 1 device and recording audio straight over the top of your video and cutting down on editing time. SENA 20S - $558 - Motorcycle Race Gear The reason I chose the Sena 20's - and the dual pack - was that I sometimes ride in a group and this intercom function would be ideal. It was also the perfect fit with the SENA Prism. I liked the design, that it was using the latest Bluetooth 4.1. Again downloading the latest firmware ensures you are up to date with all the functions. The audio cues of when things connect, disconnect are perfect and great to let you know when you stop/start recording etc. You can listen to your music, take and make calls on your phone, listen to GPS directions and of course play audio onto the SENA Prism. Getting used to the JOG dial which is a windy little wheel on the side can take some getting used to but audio quality etc is fantastic. Mic functions are great and are as clear as anything I have used in the past. Again SENA supply everything in the box, all sorts of accessories including different MIC types, chargers, pads etc. 20S - Sena Overall as a package I am really impressed by both devices. Setup was a breeze, anything you need is on their website with manuals, videos, pictures etc. I am currently editing a bit of a video of my first ride of the new Street Triple R I purchased which was made using both products. I will post that up over next few days so people have an idea but I wanted to write this up first. Summary GoPro's have a fantastic market share and so they should. Their devices are simple and do a fantastic job. SENA have really stepped up to the mark with their products and they are just as simple and easy to use and the built quality really is fantastic, quality of audio and video is great. There are some minor issues like not being able to preview video from the Prism however some of its other features such as recording audio straight over the top of video makes it a fantastic option for people looking to get into motovlogs. Cheers guys and happy riding.
