As time goes by (no pun intended), and your detector collection grows, it seems that the idea of investing in a TE detector is thought of more frequently.
"What's the big deal about time expansion detectors?" I hear you say... To put it simply, the reason why they are so desirable - Is their ability to record bats and then (have the potential to) positively identify the actual species of bat you recorded!
Let's not forget, however, that with patience and experience - One can use a good heterodyne detector, to identify a few bat species. It takes practice. If you live in Europe, I can recommend The Bat Detective CD & Booklet set, from BatBox. Check it out here: The Bat Detective
In fact, since I may not get around to writing a full review of this set - I'll say this: I recommend it very highly, I think it's awesome! And, it is nowhere near as useful to me, as it would be if I lived in Europe, so...
OK, back to time expansion - When we get right down to it, it's a matter of which one can you afford? If, you have a limited budget (as I do) then, you're always on the look-out for a new TE detector that falls within your budget.
Thankfully, there are some time expansion bat detectors that are now in their prototyping phase, that will cost just a little more than conventional detectors. This is great news! And, I will be sure to inform my readers about them, on the same day they become available!
I suppose it's safe to say, that the even better news - Is that there already is one, which is now officially on the market - Ready to order. It is the Ultramic200K, from Dodotronic, in Italy. As you know, I ordered (a prototype) as soon as it became available. I've been using it ever since, and I really enjoy it's performance. I would just like to add, that at only 200 Euros (+VAT & Shipping) - That I've been able to already start saving up for my next bat detector : )
From what I've read recently: Other owners are enjoying this mic, in the field, as well! I should also note: More than one of these Gentlemen are very experienced, and/or Professional Bat Researchers. And, they have had good things to say about this mic's performance. Excellent.
These days, what I'm looking for, in a bat detector - Is the ability to tell me, with relative certainty, which species of bat I'm picking up.
I mean, this is the ultimate goal, n'est-ce pas?
I will cover this topic some more, in future posts.
