So we got past the looooooong Jan pay-day and I am able to resume by pre-summer kit out...
Having been spurred into action by the thread about plotters/sonar on the SIB forum and having reviewed a number of options I have purchased a Garmin Echomap 45dv CHIRP...
However, I seem to be getting different advice from different places about which transducer to opt for being that this device has CHIRP
The options are:
GT21 - deep salt water; only does down vu on CHIRP (not traditional sonar) (1000+ ft)
GT22 - does both traditional and down vu on CHIRP but classified for fresh water (or some say shallow salt water) (200-500 ft)
GT23 - does both traditional and down vu on CHIRP to decent depth (1000+ ft)
The GT23 is obviously the best option, but retailing at £270 that's more than double what the other two cost and I'm trying to avoid that.
So, being left with the 21 and 22 and knowing that this will only ever be used on a SIB no more than about 3 miles from land... which is the better option?
I'm assuming the 21, but what will I lose?
I guess I don't have a great enough understanding of the different modes of operation to make the most informed decision.
