So last year I purchased a Garmin Striker 4 and I'm not super thrilled about it anymore. This year I'm looking to upgrade to a Helix 5, but I have trouble swallowing the $500 price tag for their ice fishing bundle. Would it work fine to buy the regular Helix 5, their ice transducer and then mount it on an old vexilar genz pack or something of the like? I'm fairly new to the whole using a graph ice fishing thing so I'm just checking to make 100% sure before I spend the money. Thanks for any input folks, and if anybody has any other cool ideas to mount something like this on I'd be all ears.
