Add music to your Seadoo, it sits in front of the steering console and is strapped down turning with the steering wheel.
This bag has a water resistant phone compartment and meshed pouch for a water proof speaker such as a JBL or BOSE (MICRO, they sound great) portable speaker. This is also a convenient place to have your phone as you can see incoming calls, you do not have to hear the ringer go off over the sound of the motor. I also run my fish finder (Vexilar) and GPS (Navionics) off my phone, so I love this bag keeping my display right in front of me. As a side note I also run my drone off my cell phone app, it could not be more convenient.
Attach this bag to your handle bars for extra storage. Keep your tackle, pliers, sun glasses etc here. Extra long straps designed for Jet Ski's and an upper pouch for fishing licenses and documentation. Use the top as a flat surface to put your tools and lures on while you get ready to fish.
Extra long straps needed to fit the steering of a Jet Ski, normal handle bar bags will not cut it, their straps are generally too short for PWC's.
