My Bottom Line 4200 fish finder is now toast. I miss it dearly. Attempting to find a replacement that I can use on my 8' foam filled pond hopper....AND use it on my 8' inflatable toon with frame and oars.....has been frustrating.

Is there anyone who knows what would work good? Garmin Striker Portable kit would work good on the hard boat...but on the inflatable? Everything I find on the internet has compliments...AND negative comments about them.

tks n advance
