The other drawback, at least for me, is the lack of a dedicated squelch knob. Instead it has a two-button operated squelch, with 11 possible settings ("open" and 10 "squelch" levels). In fairness, this setup is quite common among currently available waterproof handhelds. Very few have the traditional squelch knob anymore.
Finally, this radio is a bit pricier than most other waterproof handheld marine VHF radios. Whether this extra cost is justified or not, I can't say, since I have only limited experience with other similar radios. But I can say that my IC-M88 has seen much use, and some occasional accidental abuse, over the 5+ years I have owned it, and still looks and operates just like it did the day I bought it.
It has its own little criss-cross bungees to make up for the bungee space it takes up on the forward deck of your kayak. There is even a little zipper at the bottom where you can store lip wax or other small items. It has a non-skid bottom surface to help it stay put on the kayak deck. It even comes with a handy whistle clipped to the drinking tube, and of course has all of the standard hydration pack features one expects from Camelbak, like interior webbed reservoir, large filling opening, quick detach tube, bite valve cover, etc. There are definitely reasons why Camelbak is a leader in the active outdoor activities hydration business.
When I first got this water pack, It seemed to me that the hooks for attaching it to the kayak bungees might be a bit small, and the gates on them might possibly be susceptible to damage with repeated use. However, after over a year of use, they all still work just fine. Not counting required gear like a paddle and PFD, this is definitely the best, and most used, kayak accessory that I have, and I highly recommend it!
As I mostly paddle solo in somewhat remote areas of the Florida Keys, safety is always a concern. With this PFD, if for whatever reason I should ever get separated from my kayak, I can still have some basic safety gear with me, like a VHF radio, signal mirror, whistle, flashlight, knife, camera (with flash that can be used as a manual "strobe" light), small tube of sunscreen, etc. The Bahia Tour also has two strap attachment points, one front and one rear, for anything else that you might want to have connected to you.
